So I saw Chacha with this hair loss on her ears last year this time. She was not at my kennel yet, and it cleared up naturally. I assumed it was allergenic. But, she's at my house this year, and when she broke out, I had some testing done to see what it is.
I have her separated from the other dogs, and I just got the diagnosis a few days ago. Tricophyton Fungus, so I guess ringworm. The symptoms in Chacha are hair loss on ears with a bit of scabbing. The hair dies and can be plucked off leaving bare skin. Anyway, just putting this out there for educational purposes. Hopefully I'll get this cleared up quickly and for good.
