My male was the same way. I fed him a dry kibble with a little chicken broth and he was fine. He also would eat grass the vet said that was because of acid in his stomach. I would give him a teaspoon of peanut butter at night with a pepcid AC and voila it was cured.
My 14 year old female is developing kidney disease. She is very active and does well but is now drinking more and having accidents if I am gone too long. I'm thinking of trying diapers and am wondering if anyone has experience using these. If so what seem to be the best kind? Disposable or washable?
