*Note: I have no connection to Purina in any way* My Pugs have been fed Purina O.N.E. since they've been on solid food. Starting with the puppy formula. They've always been healthy, but they've also always had an open dish menu. When they eventually Pugged-up we switched to the healthy weight management formula and after 8 months the vet says they are both within 2 pounds of ideal weight, even though the open bowl policy is still in effect. Maybe O.N.E. is vastly different from other Purina formulas, but it almost sounds like P.E.T.A. is trying to slam Purina for some reason. Canines are carnivores by nature, and denying them flesh is just wrong. Forcing your dog to eat a vegetable-based diet is cruel. *end political rant* ;)
