Cruise has been eating Wellness Just for Puppy brand food for the past 3+ months. He usually eats like a vaccuum cleaner! I started a new bag the other day and he won;t touch it. I was concerned he was not feeling well so I gave him a dog cookie...no problem there he ate it. I added pineapple to his food (I do occasionally so that the 2 corgi's don't eat their poo) and he ate just the pineapple. This morning I tried again..he did not touch it. So I gave him a bowl of Tiki's food and he devoured it. Stupid question, but have you ever heard of a "bad" bag of dog food?
