Royal Canin Veterinary Diet Canine Gastrointestinal High Fiber (Adult, Dry) is a dry kibble in Royal Canin's veterinary exclusive lineup, sold as 8.8 and 17.6 lb bags. Royal Canin describes it on the product page as "Complete and balanced food for adult dogs." 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 chicken by product meal, brewers rice, pea fiber, chicken fat, and wheat. Its crude fiber guarantee of 7.9 to 13.3 percent runs well above the base Gastrointestinal recipe's 3.7 percent maximum, and Royal Canin adds wheat gluten and corn protein meal to this recipe's ingredient list where the base recipe does not use them. Dogs who lose interest in a rotation often take it again with a single ingredient freeze dried topper crumbled over the top. Ask your veterinarian before feeding any therapeutic diet.
