My puppy has diarrhea with blood and mucus
Hi I need some help. My 4 month king charles has diarrhea with blood and mucus for the last 5 weeks. He has been to the vet 3 times and had 3 courses of antibiotics. A sample of his stools has been sent to a lab and all tests came back clear. We have noticed balding patches and a very dull coat recently. The vet suggested that I change his food which I did but the problem still persists. He is up to date on all his vaccinations and has been wormed. Please help as its getting very worrying. Thanks. Barbara.
