Hi, hoping that you dog experts could maybe help? I have a 9yo Jack Russell, who is very prone to ear infections, he averages 5 a year, and the vet treatment is getting very expensive! They discharge slightly, it's not canker, the inside of the outer ear gets a bit crusty and he's really uncomfortable. Although he hasn't had an EUA the vet's pretty sure it's not something trapped down there. Any ideas on prevention or cure (at around £70 a visit, it's a bit draining at the mo). The vet prescribes anti b's and ear drops, but I have tried Chlorhexidine which gave a little relief.
