Hi, My dog has some black stuff in his ears so i took him to the vet. The vet said it was wax so he prescribed a wash and Surolan drops. After two days of giving him the drops he started to act funny, when he runs he has his head done to the side and runs kind of sideways like hes dizzy or something. He also just lays around and doesnt eat very much. I stopped giving him the drops for 3 days to see if he would get any better but hes still the same should i start giving him the drops again? or go back to the vet?
