Q. I rescued my Lily at 7months and she was eating Purina puppy chow. I transitioned her to Blue Wilderness and since then she has had GI issues?

A. Stomach upset is a very common problem in our pets and occurs for may different reasons. As a general rule when you switch from one dog food to another it is always a good idea to make a slow transition from one food to the next. Most people would agree that you should mix a small amount of the new food in with the old food and gradually decrease the old food amount and slowly increase the new food amount until you are feeding mostly new food. You may also want to try going back to your old Purina diet until the GI issues quiet down and then try a slower transition to the new diet.
