Hills Science Diet Puppy Food Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Hill's Science Diet is the best-performing hills science diet puppy food brand in July 2026, moving 60,000 units across 5 ASINs for 37.5% of Top 10 volume. Milk-Bone follows with 40,000 units (25.0%), ahead of GOOD 'N' FUN on 20,000 units (12.5%).

With 6 brands splitting the Top 10 and 75.0% 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 $11.48 to $43.99, which frames the price band a competing listing has to justify.

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. On the growth side, B09R6CH93J leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0018CI998 close behind at ▲ 28.6% MoM on 9K units.

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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
