Just querying to see if anyone knows much about this. My 3 year old girl may have otitis media. She has been on antibiotics for 6 weeks as she has a swollen ear drum. My vet has been checking up with the university vets as he has not seen this in 10 years. She may have to have an x-ray for a diagnosis or possible operation. He said it is only because she is a cav and is soooo good that he can actually see it. Anyone had this problem before?
