Mine wsa doing fine for a bit, but then got disinterested in his food. I switched brands to Nutro (gradually) and still no interest. He actually went 2 days with hardly any of it. He is playful and fine, so it was not a matter of being sick. I desperatly put some chicken broth in his food and he ate it all! But after two days of this, he is again disinterested in it. Should I try switching his food again? I thought about adding other stuff, but he would just "pick around" it if it was in his dish. Does Canidae have good canned I could mix in? I don't mind giving him canned, but have heard that with puppies, until they are completely housebroken, you want to avoid canned due to all the moisture.
