We tried her on SO many different kinds of food. She wouldn't eat any of the "high" end ones. She loves the Chef Michael (I'm sure that isn't the greatest) and I recently have started mixing in the Iams Healthy Naturals to slowly switch her over to that. So far she seems to like that. As far as treats..............I give her milk bones and every so often (not to often) those Cesar Softies. She doesn't get a lot of either one though. I do control the treats!!!! She loves chew sticks.............maybe I shouldn't be giving her those! Do you think this is my fault? Am I feeding her all wrong? I have never had a dog this small before................I feel pretty helpless.
