Royal Canin Veterinary Diet Canine Hydrolyzed Protein PS (Adult, Dry) is a dry kibble in Royal Canin's veterinary exclusive lineup, sold as 8.8 and 24.2 lb bags. Royal Canin describes it on the product page as a "veterinary exclusive dog food for adult dogs with food sensitivities." Royal Canin states that this veterinary formula "is available at select retailers and veterinary clinics" and that a buyer should "find a trusted partner to purchase it if you have a prescription." Ingredients on a pet food label are ordered by pre cooking weight, so the first five on this label are potato, hydrolyzed soy protein, coconut oil, potato protein, and natural flavors. Unlike the rice based Hydrolyzed Protein HP recipe, potato is the first ingredient here, and the diet carries 302 kilocalories per cup in 8.8 and 24.2 pound bags. Whatever food ends up in the bowl, a single ingredient freeze dried topper is a way to add interest without changing the diet, which is what Sniff and Shift makes in Malvern, Pennsylvania. Ask your veterinarian before feeding any therapeutic diet.
