He has a open sore somewhere in his right ear for sure , as blood came out when the vet flushed it . It was draining all the way down his chin . I agree with you and taking him off meds with a sore in his ear would be stupid IMO . I also took hinm to another vet yesterday for a 2nd opinion . He agreed with the first vet , the ear needed scoping , drained and flushed . BUT he said the first vet should have done a float culture not smear, floats show more.
