Well i need to try some thing new because Chewy docent like the ekanuba and isn't eating much at all... I tried the nutro and it gave him diarrhea but now I'm wondering if it was just that his system was getting messed up with the change. I tried doing it little at a time but then had to do the whole chicken and rice thing... Now I am adding the dog food to the rice... HUH I don't know what to do with him. maybe I'll try the Nutro once more before I write it off! how many days do you add the old food and the new food before you can just give them the new food by itself??? HELP!
