SmartScout data shared with GlobalPETS estimates that Amazon’s first-party pet vendors generated 23.4% of the platform’s US pet-category revenue, or $322 million per month on average, during the 12 months ending Aug. 11, 2026. Total US pet sales on Amazon, including third-party sellers, grew 32.6% to roughly $1.4 billion monthly; the figures are platform estimates, not a measure of the entire US pet market.
Amazon’s first-party pet vendors accounted for 23.4% of monthly US pet-category revenue, averaging $322 million per month, according to SmartScout data shared with GlobalPETS. The estimate covers sales over the 12 months from Aug. 11, 2025, to Aug. 11, 2026, and comes as all pet sales on Amazon in the US grew 32.6% to roughly $1.4 billion monthly, including purchases from independent third-party sellers.
The 23.4% figure refers to sales made by vendors that sell products directly to Amazon, which then owns the inventory and sells it to customers. SmartScout’s estimate places pet at 13th among 29 categories it analyzed for the share of category revenue coming from first-party sales. The report does not describe this share as Amazon’s portion of the entire US pet market; it concerns sales on Amazon’s platform.
First-party participation differs considerably by product. Amazon sales represent 78.6% of dog-food revenue on the platform, 89% of cat-food revenue, 84.5% of treat revenue and all revenue for pet insect supplies, according to the report. Third-party sellers, who list and sell their own products through Amazon, lead in some other areas, including horse, bird and amphibian food and health supplies.
Across the US pet category, sales from Amazon and third-party sellers together reached roughly $1.4 billion per month and more than 54 million units sold, GlobalPETS reported, citing SmartScout. That total was up 32.6% over the 12-month period. The platform’s dog category generated an estimated $877.4 million in monthly revenue, compared with $402.2 million for cat products; those animal-category revenue figures relate to a separate period, July 21, 2025, to July 21, 2026, in the source report.
First-Party Sales Shape Pet Shopping
The data points to a substantial role for Amazon as both marketplace and retailer in online pet shopping. In first-party sales, Amazon buys and holds the products, rather than simply providing a storefront for a seller. That distinction matters to suppliers weighing sales channels and to third-party businesses competing for customers on the same platform.
SmartScout CEO Scott Needham told GlobalPETS that bulky products such as dog food can be cost-prohibitive for third-party sellers because of shipping and logistics costs. He said Amazon’s different logistics pricing for oversized vendors pushes some of that category toward first-party sales. This is Needham’s explanation of the pattern, not a finding that every dog-food seller faces the same costs or that logistics alone accounts for the market share.
The growth figures also differ by seller type. Needham said annual growth for first-party pet brands is 34%, compared with 108% for third-party pet brands. The source does not provide the underlying brand counts, revenue bases or detailed calculation method for those growth rates. The figures therefore offer a reported comparison, but not enough information to determine how growth is distributed across companies or product lines.

How Amazon’s Pet Market Is Divided
Amazon’s first-party share in pet supplies sits close to several other consumer-goods categories in SmartScout’s comparison. The reported shares were 26.2% for beauty and personal care, 23.7% for baby products and 18.5% for home and household. Pet’s 23.4% share was below categories led by Amazon devices and accessories at 88.5%, classification and ranks at 81%, and books at 71.8%.
The broader category is not growing at the same rate in every segment. SmartScout’s average of 12-month growth rates for individual subcategories put terrarium products at 51%, followed by cat products at 48%, bird at 32%, aquarium at 28%, small animals at 21% and dog at 16%. These are subcategory growth figures, not the overall 32.6% US pet-category growth rate.
Competition also varies by product. The report says more than 2,000 brands sell basic dog collars on Amazon, while more than 1,840 compete in dog chew toys. Dog beds and dog treat cookies, biscuits and snacks also rank among the platform’s most competitive subcategories. These counts describe brands present in the named Amazon subcategories; they do not establish how much each brand sells.
The report also identifies different first-party shares in other national Amazon markets. Canada had the highest monthly first-party pet revenue outside the US at $64 million, equal to 19.6% of sales there; the UK recorded $41.3 million monthly and a 24.1% share. Italy, Spain and Australia had first-party shares above 38%, although their reported monthly revenues were lower. These comparisons concern Amazon sales in each country, not total national pet spending.
“Some categories such as dog food are “cost-prohibitive” for third-party sales on the platform.”
— Scott Needham, SmartScout CEO, speaking to GlobalPETS
Limits of the Sales Estimates
The reported figures are SmartScout estimates reported by GlobalPETS. The material does not explain the platform’s full methodology, how it distinguishes revenue by seller type, or whether the figures account for returns, promotions or other adjustments. The figures should not be treated as audited financial disclosures from Amazon.
It is also unclear from the report how the 32.6% growth rate compares with changes in prices, product mix or unit volume across the full 12-month period. Although the source gives a total of more than 54 million units sold, it does not provide a corresponding earlier unit total. The available information also does not show how much of the growth came from Amazon’s first-party business versus third-party sellers.
The 23.4% share is limited to pet sales on Amazon in the US. It does not show Amazon’s share of all US pet-product purchases across online and physical retailers, and it does not establish whether the marketplace’s share is rising or falling over a longer period.
Further Data Needed on Growth
The report offers a snapshot for the stated 12-month periods, but it does not identify a scheduled follow-up or provide an Amazon response. A later SmartScout update could show whether first-party and third-party growth rates persist, and whether Amazon’s share changes across food, accessories and other pet subcategories.
For a clearer view of the market, subsequent data would need to set out the calculation method, comparable prior-period revenue and unit sales, and the contribution of each seller type to category growth. Until those details are available, the figures indicate the scale and reported direction of sales on Amazon, while leaving the drivers and broader US market implications unresolved.
Key Questions
It means vendors selling pet products directly to Amazon accounted for an estimated 23.4% of monthly US pet-category revenue on Amazon during the measured period. It is not Amazon’s share of all US pet-product sales.
How much revenue did Amazon’s first-party pet sales generate?
SmartScout estimated an average of $322 million per month in first-party pet revenue on Amazon in the US over the 12 months ending Aug. 11, 2026.
How quickly did total US pet sales on Amazon grow?
Sales from Amazon and third-party sellers combined grew 32.6% over 12 months to roughly $1.4 billion per month, according to SmartScout data reported by GlobalPETS.
Which pet products had the highest first-party shares?
The report lists pet insect supplies at 100%, cat food at 89%, treats at 84.5% and dog food at 78.6% of platform revenue from Amazon sales. The figures refer to Amazon’s sales within those product categories.
Does the data show why Amazon pet sales are growing?
No. Needham cited logistics costs as one reason bulky products such as dog food may favor first-party sales, but the report does not break down the causes of overall category growth or provide enough detail to attribute that growth to a particular seller type.
