Was wondering if she is having a reaction to the changing of foods? When I changed my furbabies over to Canidae it took me about three weeks to get it done slowly so it wouldn't upset their digestive tract. Here's a site that you can find what are the recommended dog foods.
Pet Food information, manufacturers, products, ingredients, cat, dog, pet food. Good luck. Hope someone comes on who is more experienced than I am.
