Amazon’s annual Pet Days event continues to reshape the U.S. pet supply landscape, generating $397.8 million (€341M) in sales between 11–15 May 2026, according to Similarweb data. This represents approximately 16.7 million units sold across the platform.
The 2026 edition marked Amazon’s largest Pet Days yet, expanding from a two‑day event in 2025 to a five‑day campaign. Despite the extended duration complicating year‑over‑year comparisons, sales value still increased 8.1%, while unit volume rose 3.9%.
Product visibility also surged, with 84.3 million product views, up 4.4% from 2025—highlighting growing consumer engagement with pet‑focused promotions.
