Both dogs have had this before and have it now. Temperal-P is drying up ears and no bumps or scabs on belly.Where the bumps are healing there is no hair and it has a kind of polka dot circular pattern. The weimaraners symptoms look different-scattered pustles on left side of face and body and chin. His ears are totally fine. He is not on any meds as his symptoms were much milder and was hoping to avoid any steroid or antibiotics. They do itch but not constant-sporadic. They hunt daily in the woods and recently encountered a fox,why I am worried about mange.Last time this was a major problem it took months to resolve and thousands in vet bills w/no firm diagnosis and never really knew if revolution helped or if the seasons changing killed what ever they were contacting!I'm wondering if any of those mange cures work(Happy Jack,sulfer drugs etc..anybody else with this problem?
