So glad there is progress.
From what you wrote, Ollie does not have cutaneous vasculitis... correct? Instead he has EM? But, he is being treated with the same kind of medicine that would be used for this disease?
Just wanted to add that when Piccolo's biopsy was first sent out they said she had something else. (I need to look it up what the report said, something like dermotomyocytis) Then we had the results sent out again. Her vet dermatologist said that she thought this was not correct, but the only way we would know for sure was to do a muscle? biopsy. I decided against that because it would be treated with the same medicine and why put her through that. Anyway, I guess there is a group of diseases that are close to each other that can be treated with pentoxyphilline and prednisone.
Thanks for the update and sounds like Ollie is doing well.
