I switched my dogs from Eukanuba over to Blue Buffalo almost a full month ago. I've heard that when you switch foods it's not unusual for the dog to have loose stools and gas. My question is, how long do these things typically last? Misty had solid stools on Eukanuba, but they are a bit looser now.. Abby had loose stools on Eukanuba and they don't seem to have improved much, and Abby has been having terrible gas. It doesn't seem to bother her, but she stinks up the room pretty quickly whereas she didn't have this problem on Eukanuba. Is this still considered normal, or is it time to try a different brand?
