Amazon's Expanded Pet Days Event Drove Sustained Sales Growth

Amazon Pet Days has quickly become one of the most important promotional events on the pet ecommerce calendar. In 2026, Amazon expanded Pet Days from a two-day event to a five-day promotional window running May 11–15, giving pet owners more time to shop deals across food, treats, wellness products, and supplies.

The expansion paid off. Amazon pet product sales remained above 2025 levels throughout May 2026, with the largest lift occurring during the five-day event itself. Unlike the 2025 promotion, which produced a brief sales spike concentrated over two days, the 2026 event generated elevated daily spending across the entire promotional window. Sales increased ahead of the event and remained strong throughout, resulting in more consistent performance than the prior year.

Which Pet Categories Gained the Most Share During Pet Days 2026?

The 2026 Pet Days event reshuffled category share in a clear direction: everyday consumables gained ground while supplies and accessories declined.

The pattern is clear: shoppers used Pet Days to restock consumable pet products; food, treats, and supplements, rather than purchasing durable goods or equipment. This aligns with broader pet ecommerce trends showing that online pet food and treat sales continue to grow faster than pet supplies and accessories.

Pet Supplement Brands and Wellness Products Led Share Gains

One of the most notable findings from the 2026 Amazon Pet Days data is the performance of pet wellness brands, particularly in the Dog Vitamins & Supplements category.
