Why this is your pick
Hill's and Royal Canin are the two brands veterinary nutritionists recommend above all others. Science Diet uses slightly more whole-protein ingredients and typically costs 10–15% less than Royal Canin. A near-equal choice if your vet specifically recommends it.
Pros
- Slightly lower price than Royal Canin
- Whole-protein first ingredient
- 30+ years of clinical research
Cons
- Size-specific formulas less granular than Royal Canin
- Slightly lower palatability scores in blind feeding tests
