I would get them to a vet teaching hospital ASAP, if it’s possible for you - that is disturbing!
I had her to the vet and she just said Pepper had yeast infection, I had somestuff to clean her ears everyday and put in some drops. Its almost like getting worse since I started that....I think the U of Michigan has a vet college. My daughter had her horse up there twice...I’ll talk to her about where exactly to go....thanks...
