It sounds like Buster's tummy is upset. This could be due to many reasons including bacterial overgrowth, a medication reaction, stomach acid, dietary intolerance or perhaps an oncoming disease like kidney disease. I recommend to play it safe and have Buster examined. The doctor may recommend to check his blood levels to make sure everything is ok internally. The vet may also try a bland diet, probiotic, recommend parasite testing or medication to soothe his tummy. I hope this helps and please feel free to post any additional questions.
