Science Diet is the veterinary community's most-cited recommendation for dogs with health conditions. Formulated with clinical nutrition research and one of the original WSAVA-compliant brands.
Hill's is the food vets reach for first when a dog has a health issue — the prescription line is unmatched, and even the standard kibble has decades of clinical research behind it.
“There's 5 brands in the United States that meet WSAVA guidelines: Purina, Hills Science Diet, Royal Canin, Iams, and Eukanuba.”
