I have been giving my dogs the MB beef basted biscuits, and I have noticed that they get loose stools everytime I give that flavor to them. Is there an ingredient that is in there that is doing that, that I need to watch out for? It doesn’t affect all the dogs, just a few of them. I’m giving them the Old Roy brand now, and they seem ok. The plain large MB dog biscuits doesn’t seem to affect them.
