The best pet calming supplements depend on your animal’s needs, preferences, and the situation you’re trying to manage. My best overall pick is Purina Pro Plan Veterinary Supplements Calming Care for its distinct daily-supplement approach; Rescue Remedy Pet Stress Support Drops stand out for caregivers seeking a liquid option for dogs or cats, while VetriScience Calm & Confident offers a veterinary-strength chew format for both species. The main tradeoffs are chews versus drops or powders, single-ingredient simplicity versus blends, and routine support versus products intended for occasional use. Ingredient lists and serving directions vary, so a familiar flavor or large package alone does not make a supplement the right fit. Read on for the full breakdown and a guide to choosing among all 15 options.

Key Takeaways
- Purina Pro Plan Calming Care leads for a daily routine: its supplement format sets it apart from the lineup’s many treat-style chews, though it may not suit pets that reject powders or food mix-ins.
- Rescue Remedy and Charlie & Buddy give liquid users alternatives: drops and oil can work for pets that resist chews, but dosing and administration may take more caregiver effort.
- Several picks explicitly cover both dogs and cats: Rescue Remedy, Pet Naturals, VetriScience, and Charlie & Buddy offer cross-species labeling, unlike the dog-focused options.
- Ingredient blends vary widely: products featuring hemp, melatonin, herbs, or other formulas are not interchangeable; match ingredients and directions to the pet rather than assuming a longer ingredient list is better.
- Package count is not a direct measure of value: serving sizes, pet size, and directions shape how long a package lasts, so compare the label’s suggested use instead of choosing by count alone.

More Details on Our Top Picks
Hemp Calming Chews for Dogs – 240 Treats
For dog owners seeking one chew for several predictable stressors, this formula pairs hemp, valerian root, chamomile, and melatonin and is described for situations such as separation, travel, and storms. Its 240-treat quantity may suit households that want a larger supply, while the chicken flavor gives the chew a familiar treat format. Compared with Rescue Remedy Pet Stress Support Drops, this is a dog-only chew with a broader listed ingredient blend; Rescue Remedy is sedative-free and works for both dogs and cats, but its claims rely on traditional homeopathic practices rather than accepted scientific evidence. The tradeoff here is melatonin: owners should check with a veterinarian before use when a dog has health conditions or takes other medication. Chicken also rules it out for dogs with poultry allergies, and the supplied information does not give ingredient amounts.
Pros:- Combines hemp, valerian root, chamomile, and melatonin in one chew
- Described for several common stress situations, including travel and storms
- Large 240-treat quantity suits households seeking a bulk supply
- Veterinarian-formulated and made in an FDA-registered facility, according to the supplied product information
Cons:- Contains melatonin, which may not suit every dog’s health circumstances
- Chicken flavor is unsuitable for dogs with poultry allergies
- Ingredient amounts and serving guidance are not provided in the supplied details
Best for: Dog owners who want a large supply of chicken-flavored chews for recurring travel, separation, or noise-related stress.
Not ideal for: Dogs with poultry allergies or health conditions that make melatonin a concern, unless a veterinarian approves the formula.
- Form:Chews
- Quantity:240 treats
- Flavor:Chicken
- Primary ingredients:Hemp, valerian root, chamomile, melatonin
- Target audience:Dogs of all sizes and ages
- Item weight:0.56 kg
- Origin:Made in USA
Our verdict“Choose this bulk dog-chew option for a multi-ingredient approach to recurring stress, provided chicken and melatonin fit your dog’s needs.”
Rescue Remedy Pet Stress Support Drops for Dogs and Cats, 10 mL
Rescue Remedy Pet Stress Support Drops is the lineup’s clearest fit for households that want a liquid, sedative-free product usable for both dogs and cats. The drops can be given by mouth or mixed into food, water, or a treat, which offers more delivery flexibility than chew-only choices such as Pet Naturals Calming Chews. Its vegan, non-alcohol formula also avoids several listed dietary ingredients. The key limitation is evidence: the calming claims are based on traditional homeopathic practices and are not supported by accepted medical or scientific evidence, and the product is not evaluated by the FDA. I would not treat it as a proven substitute for veterinary advice or care, especially for persistent or severe anxiety. The small 10 mL bottle may also be less convenient for people who prefer a longer-lasting supply.
Pros:- Suitable for both dogs and cats
- Sedative-free formula
- Can be administered by mouth or mixed into food, water, or a treat
- Vegan, vegetarian, non-alcohol, and free of grain, wheat, corn, and soy
Cons:- Effectiveness claims rely on traditional homeopathic practices, not accepted medical or scientific evidence
- Not evaluated by the FDA
- The 10 mL bottle is a small-format option
Best for: Dog-and-cat households looking for a sedative-free liquid that can be mixed into food or water.
Not ideal for: Owners seeking a calming supplement supported by accepted medical or scientific evidence, or those who prefer a larger-volume format.
- Form:Liquid drops
- Volume:10 mL
- Pet types:Dogs and cats
- Active ingredients:Bach natural flower essences
- Sedative-free:Yes
- Dietary attributes:Vegan, vegetarian, non-alcohol; no grain, wheat, corn, or soy
- Origin:Made in the UK
Our verdict“Pick these drops for flexible, sedative-free use across dogs and cats, but not if you require evidence-backed calming claims.”
Calming Chews for Dogs with Hemp, Melatonin, and Chicken Flavor
This chew brings together hemp oil, valerian root, chamomile, and melatonin for dog owners who want several calming ingredients in one product. The description names common use situations—including vet visits, travel, thunderstorms, and separation—so it may appeal to people planning around specific events. Compared with Hemp Calming Chews for Dogs – 240 Treats, the ingredient blend is similar, but that alternative clearly states its 240-treat quantity; this listing provides no count, ingredient amounts, or dosage details. That missing information makes it harder to compare supply and plan use, despite the veterinarian-formulated positioning and stated US manufacture. Melatonin may not suit every dog, so veterinary guidance is sensible when health conditions or other treatments are involved. The chicken flavor is another limitation for dogs with poultry sensitivities.
Pros:- Combines hemp oil, valerian root, chamomile, and melatonin
- Description names travel, storms, vet visits, and separation as intended use situations
- Veterinarian-formulated, according to the supplied product information
- Made in the USA
Cons:- No ingredient amounts or dosage details are provided
- No package quantity is stated in the supplied specifications
- Contains melatonin and chicken flavor, which may not suit some dogs
Best for: Dog owners drawn to a veterinarian-formulated, multi-ingredient chew for planned stressors such as travel or storms.
Not ideal for: Buyers who need clear serving guidance, ingredient quantities, or a stated package count before choosing a supplement.
- Form:Chews
- Flavor:Chicken
- Key ingredients:Hemp oil, valerian root, chamomile, melatonin
- Formulation:Veterinarian formulated
- Country of manufacture:USA
- Suitable for:Dogs of all ages and sizes
Our verdict“Consider this chew for its listed multi-ingredient blend, but choose a better-documented option if dosage and package size guide your decision.”
Pet Naturals Calming Chews for Dogs and Cats, Chicken Flavor, 160 Count
Pet Naturals Calming Chews earns its place through a dog-and-cat formulation and a different ingredient approach from the hemp-and-melatonin blends elsewhere in this group. Its listed actives—colostrum, thiamine, and L-theanine—make it a distinct choice for owners who want to avoid selecting a chew built around melatonin. The soft chews can be offered daily or as needed for events such as grooming, travel, storms, or fireworks. Compared with Rescue Remedy Pet Stress Support Drops, it trades liquid flexibility for a treat-style format and a clearly stated 160-count package; Rescue Remedy is also sedative-free but relies on traditional homeopathic claims. This product’s chicken-liver flavor may not work for every pet, and the supplied details give no serving amounts or evidence of results, so buyers should check the label for pet-specific directions.
Pros:- Suitable for dogs and cats of all sizes
- Can be given daily or as needed
- Uses colostrum, thiamine, and L-theanine rather than a listed melatonin blend
- 160-count soft-chew package; no corn, wheat, or artificial flavors
Cons:- Chicken-liver flavor may not suit every pet
- Supplied details do not include serving amounts or ingredient quantities
- Soft-chew format may not work for pets that refuse treats
Best for: Households with both dogs and cats that want a soft chew with a stated 160-count supply and no listed melatonin.
Not ideal for: Pets that reject chicken-liver flavor, or owners who need ingredient quantities and serving directions from the supplied product information.
- Brand:Pet Naturals
- Form:Soft chews
- Quantity:160 chews
- Flavor:Chicken liver
- Suitable for:Dogs and cats of all sizes
- Active ingredients:Colostrum, thiamine (vitamin B1), L-theanine
- Use:Daily or as needed for calming support
- Item weight:8.48 ounces
Our verdict“Choose this for a shared dog-and-cat soft chew with a non-melatonin ingredient profile, if both pets accept the chicken-liver flavor.”
NaturVet Quiet Moments Calming Plus Hemp Dog Supplement, 180 Soft Chews
NaturVet Quiet Moments Calming Plus Hemp is a practical choice for dog owners who want a large soft-chew supply stored in a resealable jar. Its listed ingredients—melatonin, ginger, L-tryptophan, and thiamin—differ from the hemp, valerian, and chamomile blend in Hemp Calming Chews for Dogs – 240 Treats. Both target familiar stressors such as storms and travel, but the 240-treat option has a larger stated quantity, while NaturVet’s 180-count jar offers a packaging detail aimed at keeping chews contained between uses. The formula is intended for dogs over 12 weeks and is made in the USA in a cGMP-compliant facility, according to the supplied details. The listing does not provide dosage instructions, so buyers should check the package directions; melatonin also makes veterinary guidance sensible for dogs with relevant health concerns.
Pros:- 180 soft chews in a resealable jar
- Lists melatonin, ginger, L-tryptophan, and thiamin
- Intended for stress associated with separation, storms, grooming, and travel
- Made in the USA in a cGMP-compliant facility, according to the supplied information
Cons:- No dosage instructions are provided in the supplied text
- Intended only for dogs over 12 weeks
- Contains melatonin, which may require veterinary guidance for some dogs
Best for: Dog owners seeking a resealable soft-chew jar for a dog over 12 weeks who experiences predictable stress around travel, grooming, or storms.
Not ideal for: Puppies under 12 weeks, owners needing serving directions from the listing, or dogs for whom melatonin is not appropriate.
- Brand:NaturVet
- Product type:Dog calming supplement
- Form:Soft chews
- Quantity:180 soft chews
- Key ingredients:Melatonin, ginger, L-tryptophan, and thiamin
- Intended for:Dogs over 12 weeks
- Packaging:Resealable jar
- Made in:USA
Our verdict“Choose NaturVet for a resealable 180-chew jar and a distinct ingredient blend, after checking serving directions and melatonin suitability for your dog.”
Zesty Paws Calming Chews for Dogs, Peanut Butter, 90 Count
Zesty Paws stands out for ingredient variety: the peanut-butter chews combine Suntheanine (L-theanine) with ashwagandha, valerian root, passionflower, magnesium citrate, L-tryptophan, hemp seed powder, and ginger root. That broad mix makes this a fit for owners seeking a multi-ingredient supplement for everyday nervousness or hyperactivity, rather than a product centered on one active ingredient. Compared with Purina Pro Plan Veterinary Supplements Calming Care, which focuses on a specified probiotic strain in daily powder packets, Zesty Paws offers a chewable format and a wider list of calming-support ingredients. The tradeoff is less dosing clarity: the supplied details do not specify serving sizes, and the stated use is limited to normal stress. I would not treat it as a substitute for veterinary guidance about severe or persistent anxiety.
Pros:- Includes Suntheanine, a form of L-theanine.
- Combines several calming-support ingredients, including ashwagandha and valerian root.
- Chewable peanut-butter format may suit dogs that resist powders.
- Designed for dogs of all sizes.
Cons:- No dosage or serving-size details are provided in the supplied information.
- The stated use is limited to normal stress, nervousness, and hyperactivity.
- The broad ingredient blend may be less suitable for owners seeking a single-ingredient approach.
Best for: Dog owners looking for a flavored chew with several calming-support ingredients for routine nervousness or hyperactivity.
Not ideal for: Owners who need clearly stated serving instructions or support for severe, persistent anxiety should skip it, since the supplied product details do not give dosing information and describe support for normal stress.
- Form:Chewables
- Flavor:Peanut butter
- Count:90
- Key ingredients:Suntheanine (L-theanine), ashwagandha, valerian root, organic hemp seed powder, organic passionflower, magnesium citrate, L-tryptophan, organic ginger root
- Intended use:Calming support for normal stress, nervousness, and hyperactivity in dogs
- Target species:Dogs
Our verdict“Choose Zesty Paws if you want a multi-ingredient calming chew for routine stress and can confirm serving guidance before use.”
Purina Pro Plan Veterinary Supplements Calming Care Dog Supplement, 30 Count
Calming Care takes a more targeted route than chew-based options: each packet supplies Bifidobacterium longum BL999 at a stated 1 × 10^9 CFU, with support aimed at calm behavior during separation, unfamiliar visitors, new sounds, and routine changes. That specificity is its clearest distinction from Zesty Paws Calming Chews, whose formula combines several calming-support ingredients rather than centering on a named probiotic strain. The powder format may work well for owners who can mix a supplement into food, while the 30 individual packets make portions easy to keep organized. The tradeoff is that it is not a treat-style option, and the supplied information gives no dosing instructions beyond the contents per packet. I would choose it for a defined daily supplement routine, not as an instant-use answer to an acute stressful event.
Pros:- Names the probiotic strain, Bifidobacterium longum BL999.
- Specifies 1 × 10^9 CFU per packet.
- Designed around common stressors such as separation, visitors, sounds, and routine changes.
- Individual packets offer a simple format for organizing portions.
Cons:- Powder may be inconvenient for dogs that will not eat supplements mixed into food.
- The supplied product details do not provide dosing instructions.
- The daily packet format is less suited to owners seeking a chew for a single stressful occasion.
Best for: Owners who can add a daily powder packet to their dog’s food and want a supplement centered on a specified probiotic strain for common stressors.
Not ideal for: Dogs that reject supplements mixed into food, or owners seeking a chew for an immediate event, may be better matched to a treat-style option such as VetriScience Calm & Confident.
- Form:Powder
- Quantity:30 packets
- Probiotic:Bifidobacterium longum BL999
- Probiotic count:1 × 10^9 CFU per packet
- Intended use:Supports calm behavior and positive cardiac activity during stressful events
- Common stressors:Separation, unfamiliar visitors, new sounds, and changes in routine
Our verdict“Pick Calming Care if a food-mixable powder with a specified probiotic strain suits your dog’s routine better than a chew.”
VetriScience Veterinary Strength Calm & Confident Chicken Chews for Dogs and Cats
VetriScience is the most flexible species-wise pick in this group: its chicken-flavored, rawhide-free chews are made for both dogs and cats. The listed L-theanine and thiamine give the formula a more focused ingredient profile than Zesty Paws Calming Chews, which includes a longer blend of botanicals and other ingredients. Its stated aim of quick stress relief without drowsiness may appeal to households preparing for a specific anxious situation, though individual results can vary. The 60-count chew format is easier to offer than Purina Calming Care’s powder if a pet accepts treats. The tradeoff is that the supplied summary does not provide specific dosage instructions, so owners with both species should confirm the right amount for each pet rather than assume the same serving applies.
Pros:- Suitable for both dogs and cats.
- Rawhide-free chicken-flavored chews offer a treat-style delivery format.
- Lists L-theanine and thiamine as key ingredients.
- Designed to support calm without drowsiness or personality changes.
Cons:- The supplied details do not specify dosage instructions.
- The product description notes that effectiveness may vary between pets.
- Its short key-ingredient list offers less formula variety than Zesty Paws Calming Chews.
Best for: Households with both dogs and cats that want one rawhide-free, chicken-flavored chew option for stressful situations.
Not ideal for: Owners who need clearly stated species-specific dosing, or pets that do not accept chews, should look for a product with serving guidance or another delivery form.
- Brand:VetriScience
- Form:Chews
- Flavor:Chicken
- Target species:Dogs and cats
- Unit count:60
- Item weight:7.2 ounces
- Key ingredients:L-Theanine, Thiamine
- Allergen information:Rawhide-free
Our verdict“Choose VetriScience if you want a shared chew option for dogs and cats, but confirm each pet’s serving before use.”
Charlie & Buddy Hemp Oil for Dogs and Cats
Charlie & Buddy is the lineup’s oil-format, multi-purpose pick, combining hemp seed oil extract with omega 3, 6, and 9 fatty acids and vitamins E and B. Its listed uses extend beyond calming support to skin and coat health, digestion, appetite, and joint comfort, which may appeal to owners who prefer one liquid supplement with several intended roles. Compared with VetriScience Calm & Confident, a chicken chew focused on a specific anxious situation, this oil is positioned more broadly for ongoing wellness. That breadth is also a tradeoff: the supplied description does not establish how much of the formula supports each claimed use, and it gives no dosage guide. I would not rely on its broad claims as a substitute for veterinary care, particularly for serious symptoms.
Pros:- Oil form offers an alternative to chews and powder packets.
- Formulated for dogs and cats of different sizes.
- Contains omega 3, 6, and 9 fatty acids, plus vitamins E and B.
- Lists calming support alongside skin and coat, digestion, appetite, and joint-related uses.
Cons:- The supplied product information does not provide a dosage guide.
- Details supporting its broad range of listed uses are not provided.
- Natural flavor may be less appealing to pets that do not accept oils.
Best for: Dog and cat owners seeking a natural-flavored oil with calming support plus listed fatty acids and vitamins for broader routine wellness.
Not ideal for: Owners who want clear serving guidance or a product focused only on calming should skip it; the supplied details give no dosage and list several additional uses without supporting specifics.
- Form:Oil
- Flavor:Natural
- Item weight:2.88 ounces
- Target species:Dogs and cats
- Active ingredients:Hemp seed oil extract, omega 3, 6, and 9 fatty acids, vitamin E, vitamin B
- Pet sizes:Small, medium, and all breeds
- Listed uses:Calming support, immune support, joint health, skin and coat health
- Allergen information:Codfish-free, dairy-free, gluten-free, soy-free
Our verdict“Choose Charlie & Buddy if you want an oil for dogs or cats with broader listed wellness uses, and verify the serving instructions first.”
Pawzitive Pets Calming Chews for Dogs with Hemp, Melatonin, Chamomile, and Passion Flower, 120 Soft Treats
Pawzitive Pets is geared toward situational relaxation, with a formula that includes melatonin alongside hemp seed oil, chamomile, L-tryptophan, and passion flower. That makes it distinct from Purina Calming Care, which is a probiotic powder described for ongoing support around common stressors, and from Zesty Paws, whose stated use focuses on normal stress and hyperactivity. The 120 soft treats provide a familiar delivery format for dogs that take treats readily, while the listed travel, vet-visit, fireworks, and separation scenarios give owners a clearer use case. The tradeoff is limited practical detail: serving instructions are absent from the supplied information, and the formula includes melatonin, so owners should confirm suitability and timing with a veterinarian rather than guess.
Pros:- Designed for specific situations including travel, vet visits, fireworks, and separation.
- Includes melatonin alongside chamomile, L-tryptophan, hemp seed oil, and passion flower.
- Soft-treat format may be convenient for dogs that accept treats.
- The formulation is described as veterinarian-developed and made in the USA.
Cons:- No dosage or serving instructions are provided in the supplied details.
- Melatonin may not suit every dog or every use case, so owners should check with a veterinarian.
- The supplied information does not specify amounts for the listed ingredients.
Best for: Dog owners seeking a soft treat for planned stressful situations such as travel, vet visits, or fireworks, especially when relaxation and sleep support are priorities.
Not ideal for: Owners who need clear dosing information or want to avoid melatonin should skip this option unless a veterinarian confirms it fits their dog.
- Formulation:Veterinarian-developed
- Form:Soft treats
- Quantity:120
- Key ingredients:Hemp seed oil, melatonin, chamomile, L-tryptophan, passion flower
- Intended situations:Travel, vet visits, fireworks, or separation
- Made in:USA
- Target species:Dogs
Our verdict“Choose Pawzitive Pets for a soft treat aimed at planned stressful events, provided you can confirm an appropriate melatonin serving with your veterinarian.”
Greenies Calming Chews for Dogs, Chicken Flavor, 40 Count
Greenies takes a restrained approach to calming support, pairing L-tryptophan and L-theanine in a chicken-flavored chew rather than stacking a long list of botanicals. That makes it a straightforward option for owners who want a short ingredient focus for normal or occasional stress. Real chicken and no artificial flavors, colors, or fillers give it a clear appeal for dogs that are particular about treats. Compared with Pet Honesty’s broad blend, Greenies is easier to evaluate ingredient by ingredient, but offers less variety in its listed actives. Its 40-count pack is also smaller than that product’s 90-count supply. The provided details list a capsule form despite describing chews, so I would verify the exact format and follow the package directions before buying.
Pros:- Combines L-tryptophan and L-theanine for calming support
- Made with real chicken
- No artificial flavors, colors, or fillers
- Made in the USA and carries the NASC Quality Seal
Cons:- Only 40 servings are listed, fewer than Pet Honesty’s 90-count option
- The specs say capsule while the product description calls it a chew, leaving the format unclear
- The supplied details do not give dosage guidance
Best for: Dog owners seeking a chicken-flavored calming supplement with two named calming ingredients and no artificial flavors, colors, or fillers.
Not ideal for: Owners who want a clearly documented chew format, a longer ingredient blend, or a larger count for ongoing use.
- Flavor:Chicken
- Form:Listed as capsule in specs; described as chews
- Active ingredients:L-tryptophan and L-theanine
- Benefit:Calming support
- Dog size:Medium
- Count:40
- Weight:7.3 ounces
- Allergen information:Corn-free, dairy-free, rawhide-free
Our verdict“Choose Greenies if you prefer a simple, chicken-based formula with two named calming ingredients and can confirm the product format and directions.”
Native Pet Calming Chews for Dogs, Air-Dried, 30 Chews
Native Pet is built for flexible timing: its air-dried chews are presented for daily routines or specific stressors such as travel, storms, fireworks, and vet visits. The blend includes L-theanine, melatonin, casein, and non-psychoactive hemp seed; the product specifies that the hemp is not CBD and is THC-free. Its stated aim is relaxation without sedation, which may suit owners who want support without a sedative-style product. Compared with Greenies’ shorter, two-ingredient formula, Native Pet offers a broader combination but also calls for more care around a dog’s health circumstances: veterinary consultation is advised for puppies and dogs taking medication. The 30-chew count is modest, and ongoing use may require consistency rather than occasional, event-only dosing.
Pros:- Designed for daily use or before stressful events
- Combines hemp seed, melatonin, L-theanine, and casein
- Described as supporting relaxation without acting as a sedative
- Air-dried, made in the USA, and carries the NASC Quality Seal
Cons:- Only 30 chews are included
- Consistent daily use may be needed for ongoing support
- Veterinary guidance is advised for puppies and dogs taking medication
Best for: Owners looking for a chew they can use as part of a daily routine or ahead of predictable events like travel, storms, and vet visits.
Not ideal for: Owners of puppies or medicated dogs who have not discussed supplements with a veterinarian, or buyers seeking a large-count supply.
- Form:Air-dried chews
- Count:30 chews
- Active ingredients:Hemp seed, melatonin, L-theanine, and casein
- Hemp details:Non-psychoactive hemp seed; not CBD; THC-free
- Flavor:Chicken
- Intended use:Daily support or before stressful situations
- Manufacturing:Made in the USA
- Certification:NASC Quality Seal
Our verdict“Pick Native Pet for a flexible event-focused or daily routine, provided its ingredient blend suits your dog and you are comfortable with its smaller count.”
Pet Honesty Calming Chews for Dogs with Ashwagandha, Duck Flavor, 90 Count
Pet Honesty stands out for ingredient range, combining botanicals and nutrients including ashwagandha, chamomile, valerian root, L-theanine, hemp ingredients, and melatonin. The soft duck-flavored format may help owners who have trouble giving supplements to dogs that turn down pills or familiar chicken treats. Its listed use covers travel, storms, separation, and vet visits, so the formula is aimed at several common stress situations rather than one narrow occasion. Compared with Greenies, which lists two main calming ingredients, Pet Honesty gives owners a much broader blend—but that also makes the formula less simple to evaluate, and the supplied information does not include dosage instructions. The 90-chew count exceeds Native Pet’s 30, though dog-size-specific guidance is not provided here.
Pros:- Includes a wide range of calming ingredients, including ashwagandha, chamomile, valerian root, and L-theanine
- Soft duck-flavored chews may suit dogs that refuse pills or chicken flavors
- Listed for stress-related situations including travel, separation, storms, and vet visits
- 90-count supply is larger than Native Pet’s 30-chew pack
Cons:- The long ingredient blend may be harder to evaluate for dogs with ingredient sensitivities
- The provided information does not specify dosage instructions
- Dog-size-specific directions are not included in the supplied specs
Best for: Owners who want a soft, duck-flavored supplement with a wide botanical and nutrient blend for several kinds of situational stress.
Not ideal for: Buyers who prefer a short ingredient list or need clear dosage-by-size guidance in the supplied product information.
- Count:90 chews
- Flavor:Duck
- Form:Soft chews
- Active ingredients:Valerian root, chamomile, ginkgo biloba, hemp seed powder and oil, passion flower, L-theanine, ashwagandha root, ginger root, lemon balm, L-tryptophan, magnesium citrate, and melatonin
- Benefits:Behavior support and calming support
- Dog size:All sizes
- Item weight:9 ounces
Our verdict“Choose Pet Honesty if you want a large-count, duck-flavored chew with a broad calming blend and are comfortable seeking dosage guidance separately.”
BARK&SPARK Hemp Calming Treats for Dogs
BARK&SPARK is the portability-first pick in this group: its travel-size soft chews are intended for stressful moments such as fireworks and storms. Hemp and melatonin keep the listed ingredient combination simpler than Pet Honesty’s extensive botanical blend, while a soft texture may be easier to offer than a pill. That compact format makes it a plausible fit for keeping a few chews on hand when a predictable trigger is coming. The tradeoff is limited product detail. Unlike Native Pet, which identifies several active ingredients and states that its hemp is not CBD and is THC-free, BARK&SPARK provides no ingredient amounts or dosage information in the supplied data. I’d favor it for convenience only when the package directions and suitability for your dog are clear.

Calming Chews for Dogs, 180 Count
This 180-count option is the lineup’s largest stated supply, making it more suited to owners planning regular use than BARK&SPARK’s travel-size format. Its chicken-style soft chews combine a wide range of ingredients, including ashwagandha, valerian root, chamomile, lemon balm, L-theanine, GABA, and melatonin. The product is intended for everyday routines as well as travel, storms, grooming, and vet visits, while the suggested timing of 30–60 minutes before expected stress gives more scheduling detail than the supplied Greenies information. The tradeoff is that the provided specs do not include dosage by dog size, so the large count alone does not show how long a supply will last. The GMP-compliant manufacturing claim and free-from list add useful detail, but not a substitute for dosing directions.
Pros:- 180 chews provide the largest stated count among these five products
- Broad ingredient blend includes botanicals, L-theanine, GABA, and melatonin
- Intended for daily routines and stressors such as travel, storms, grooming, and vet visits
- Soft chicken-style chews and a GMP-compliant facility are specified
Cons:- Dosage guidance by dog size is not included in the supplied information
- The extensive ingredient blend may not suit buyers seeking a simple formula
- The suggested 30–60-minute timing does not explain how much to give
Best for: Owners seeking a large supply of soft chews for a recurring routine and a range of predictable stress triggers.
Not ideal for: First-time supplement buyers who need clear dog-size dosing guidance before choosing, or owners who prefer a short ingredient list.
- Count:180 chews
- Key ingredients:Ashwagandha, valerian root, chamomile, lemon balm, lavender, passion flower, L-theanine, L-tryptophan, GABA, and melatonin
- Flavor:Chicken-style
- Texture:Soft chew
- Manufacturing:GMP-compliant facility
- Free from:Corn, soy, wheat, nut derivatives, artificial preservatives, and chemical flavorings
- Suggested timing:30–60 minutes before expected stress
Our verdict“Choose this 180-count formula for a broad, routine-friendly supply if you can confirm the correct dose for your dog before use.”
How We Picked
I compared these 15 products on the factors that change day-to-day fit: species labeling, format, ingredient transparency, serving directions, flavor or administration demands, and package size. I gave more weight to clear use instructions and a format likely to fit a repeatable routine than to broad calming claims or a large count on its own. Since supplement response can differ by animal and situation, I treated product claims as label information rather than proof of a guaranteed effect.
The order reflects how broadly useful and clearly differentiated each option appears for the stated use—not a promise that one supplement will work for every pet. Purina Pro Plan Calming Care ranks first for its distinct daily-supplement approach; cross-species options and products with recognizable format or ingredient differences follow. Chews with overlapping blends rank lower when their main distinction is less clear, while narrow fit can still make a lower-ranked pick the better match for a particular household. I also weigh practical drawbacks, including species limits, taste acceptance, measuring needs, and the possibility that a pet may refuse the format.
Factors to Consider When Choosing Best Pet Calming Supplements
Before choosing from this roundup, I’d match the supplement to the pet, the situation, and the way you can give it consistently. These broader checks can prevent common mismatches that a product name or package count will not reveal.
Match the Product to the Pet’s Species and Health
Start with the label’s intended species rather than assuming a dog product is suitable for a cat. Some picks here name both dogs and cats, while many are formulated and labeled for dogs alone. A multi-pet household may value a shared product, but the appropriate serving can still differ by animal and weight. Review the full ingredient list and serving directions with your veterinarian if your pet has a medical condition, takes medication, is pregnant, or has a history of sensitivities. Avoid adapting a dog serving for a cat or splitting a dose by guesswork. A supplement should not replace care for sudden, severe, or persistent behavior changes.
Choose a Format Your Pet Will Actually Take
Format is a practical decision, not a minor packaging detail: a supplement that stays in the cupboard cannot support a routine. Chews are convenient when a pet accepts treat textures, while drops or oil may suit animals that refuse chews but can bring extra measuring and administration steps. Powders can be easy to mix into food, yet a selective eater may detect a change and leave the meal unfinished. Try to account for texture, flavor, and where the supplement will be given before committing to a large package. Follow label directions rather than crushing, mixing, or changing a serving unless the label or your veterinarian permits it. If you share a home with several pets, store and serve products separately to avoid mix-ups.
Read Ingredients With a Specific Goal in Mind
Calming supplements use varied formulas, including hemp, melatonin, and botanical ingredients, so compare the actual labels rather than relying on the word “calming.” More ingredients do not automatically mean a better match; a shorter formula may be easier to review if your pet has known sensitivities. Take note of active ingredients, flavoring, and the amount per serving where the label provides it. If you are avoiding a specific ingredient, check the complete label, including inactive components. Ask your veterinarian about ingredient combinations when your pet uses medication or has a health concern. Choose based on a clear fit with your pet’s needs, not the number of ingredients listed on the front of the package.
Separate Daily Routines From One-Off Situations
Products can differ in how their directions frame use, so decide whether you need a routine supplement or a format intended to be given around a particular event. Do not assume a product will work immediately just because the need is urgent; check its label for timing and frequency. For ongoing use, a manageable schedule and repeatable serving method matter as much as the ingredient list. For a single stressful event, ease of giving the product may matter more than package size. Keep a simple note of when you give a supplement and what changes you observe, without increasing the serving if you do not see a quick effect. Seek veterinary guidance for persistent distress or behavior that creates a safety risk.
Compare Servings, Not Just Package Counts
A large number of chews can look like a better deal, but the label’s suggested serving determines how many days a package may last. Serving directions can vary by pet size, and some products are drops, oil, or powder rather than one chew per use. Work out the number of servings from the package instructions before comparing formats. Also account for whether your pet will reliably eat the full serving; a partly eaten chew or food bowl can make the apparent value misleading. A smaller pack may be a sensible first choice when taste acceptance is uncertain. Pay more only when the format, label clarity, or species fit gives you a practical benefit your pet needs.
Know When a Supplement Is Not the Whole Plan
A calming supplement is one possible part of a wider support plan, not a substitute for addressing triggers or seeking help. Changes to routine, safe resting spaces, gradual exposure, and training may matter alongside a supplement, depending on the situation. If distress is new, intense, or paired with physical symptoms, contact a veterinarian before treating it as ordinary nervousness. Supplements can also differ in how they fit with existing medication or health conditions, which makes professional advice especially useful for senior pets or those with ongoing care needs. Avoid combining several calming products without checking their ingredients and serving directions with a veterinarian. A clear plan helps you tell whether the chosen approach is manageable and appropriate for your pet.
Frequently Asked Questions
Can I give a dog calming supplement to my cat?
Only use a product when its label specifically includes cats and provides directions for them. Several options in this roundup are labeled for both species, but many are dog-focused, and ingredients or serving instructions should not be assumed interchangeable. Never estimate a cat’s serving by scaling down a dog’s dose. If your cat takes medication, has a health condition, or is showing a sudden behavior change, ask a veterinarian before starting a supplement. Check that the format is also practical for your cat to take safely.
Should I choose a chew, drops, oil, or powder?
Choose the format your pet will accept consistently and that you can administer according to the label. Chews are simple for pets that treat them as food, while drops and oil can be options for pets that refuse solid treats but require careful measuring. Powder may blend into a meal, though a picky eater can reject the changed food or leave some behind. Consider whether you can give the full serving reliably before focusing on convenience claims. When taste acceptance is uncertain, a smaller package can reduce waste.
How do I compare package sizes fairly?
Compare the number of labeled servings rather than the number of chews, treats, or milliliters alone. The directions may call for different amounts based on a pet’s size, and a package with many pieces may still provide fewer days of use than expected. For liquid products, use the included measuring instructions and account for the amount prescribed per serving. Check whether the product is intended for regular or occasional use before estimating how quickly you will use it. This approach gives a more useful comparison than package count by itself.
Can a calming supplement replace medication or behavior support?
No supplement should be treated as a replacement for prescribed medication or veterinary care. If your pet already takes medication, ask the veterinarian about possible ingredient or serving concerns before adding another product. For behavior concerns, routine changes, training, and management of triggers may be part of a broader plan. Seek professional advice if distress is severe, persistent, new, or linked with other physical symptoms. Do not stop or alter a prescribed treatment without guidance from the prescribing veterinarian.
What should I do if my pet refuses the first supplement I buy?
First check whether the label allows the product to be given with food or in another way, and follow its directions rather than modifying the serving on your own. A pet may reject a particular flavor or texture even when it accepts other treats, so the refusal does not establish that every format will be unsuitable. Avoid hiding an unapproved product in a meal if your pet may leave part of the serving behind. If you switch products, compare species labeling and ingredients rather than choosing only by flavor. Ask your veterinarian for help if you need a suitable option for a pet with dietary restrictions or ongoing care.
Conclusion
For most dog owners seeking a daily-routine pick, I’d start with Purina Pro Plan Veterinary Supplements Calming Care, the best overall choice in this comparison. For value, compare the serving directions on the larger-count chew options—including Pet Naturals, NaturVet, and the 180-count Calming Chews—rather than assuming count alone decides the better buy. For beginners, I’d favor a format with straightforward label directions and a manageable package, then check that the pet accepts its flavor. For a premium, veterinary-oriented chew choice, VetriScience Calm & Confident is the standout; for cat households or pets that resist chews, consider the cross-species Rescue Remedy drops or Charlie & Buddy oil. If your pet has a health condition, takes medication, or shows ongoing distress, ask a veterinarian to help select the right next step.
