I took him to the vet yesterday. He had been sneezing and having watery eyes. Then saliva started pouring out of his mouth. I thought he had gotten into poison. The vet gave him a shot to help stop the saliva. He also gave me an antibiotic. His ears are cold now, usually they are warm. I'm just worried about him. I was wondering if that was normal. The vet never did say what was wrong with him. I thought I might take him to another vet. Any suggestions?
