If Maxwell and Hogan were on Natural Balance venison and rice, I think you should check with your vet. Increased thirst, increased urination and diarrhea are symptoms of the Kidney issues of the effected dogs. While hopefully your dogs did not get the bad batch food, it might be better to be safe than sorry. I just don't know how much you can trust what the dog food companys are saying. Hope everything is OK. Hugs to you and your dogs. This whole thing is nerve racking.
