I certainly cannot follow that post with any more info other than allergies was the first thing that popped into my limited cranium.
While vacationing at a small island resort, they had two dogs. The one dog, Brownie had just terrible skin afflictions. We got talking with one of the staff and he said Brownie used to be so beautiful then someone fed him shellfish and he was never right after that again.
The island was very remote, so it was about an hour flight just to get to a place that even had a vet. So, Brownie just had to deal with it.
