Blue Buffalo tends to be rich itself. I've heard of lots of gas and GI type issues while dogs are on it. That's not say it's a bad food, some do great on it, but I have just seen that problem a lot with that particular food.
So you're not switching around so much -- maybe buy another small bag of puppy chow and gradually begin mixing with something a bit more simple. California Natural has a puppy formula, and is a very simple ingredient list, for example. |
