I have a foster dog who has very, very itchy ears. She has been to the vet twice and they see no problem no mites, no infection, no smell. She is a retired breeder who spent her life outside and one ear is thickened and dark inside with what I assume is scar tissue. The thickened ear bothers her the most but both seem to irritate her. She doesn't shake her head like some with problems she just itches them til they bleed. I dont know what else to do to help her. Any suggestions would be appreciated.
