Rose eats Bil-Jac Select, which is chicken based and does great on it! I don't really want to change her. Thats not the problem. I also mix some canned EaglePack into her food. When I used the Chicken Mixer, she had terrible gas. Last night, I gave her some chicken liver in her food and today she had bad gas again. She almost never has this problem. Does anyone else have the same problem when giving chicken?
