[Maximo]

Any recent food or treat changes -- other than amount?

I agree with Megansmomma that I wouldn't medicate unless you know exactly what is going on. One of my boys is a little sensitive and cannot even tolerate pumpkin -- the tiniest bit gives him diarrhea. When he has gastro problems, I don't mess around. We go to the vet.

I would stick with plain chicken breast and rice, and if the problem continues, testing at the vet.
