Best Science Diet Dog Food Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Hill's Science Diet is the best-performing science diet dog food brand in July 2026, moving 69,000 units across 6 ASINs for 49.6% of Top 10 volume. Purina Pro Plan follows with 50,000 units (36.0%), ahead of IAMS on 10,000 units (7.2%).
With 4 brands splitting the Top 10 and 92.8% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $37.65 to $75.98, which frames the price band a competing listing has to justify.

Trending Science Diet Dog Food Products — Growth Leaders & New Top 10 Entrants
Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B00TH3MMDE booked 9K units at $25.97, with ▲ 0.0% MoM change.
The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
