My 4 yr old QH got rain rot last year - that is now cleared up and hasn't come back. He has had scabs on his legs ever since I bought him last year. I scrubbed his legs off and on all summer (hoping not to dry them out) with betadine - scabs wouldn't go away. I finally got the scabs to go away a couple of weeks ago (early Dec). The skin underneath though is not like normal skin it still seems like its flaky, white dead skin etc. He also has constant dandruff in the winter (I live in WI) and had a patch of skin (size of a tennis ball) flake off - hair stayed but scabs/skin rose to the surface.
I give him soy oil to hydrate his skin but is there something else I should be trying. I have called a vet about this also - they didn't say much just athat he is young. This skin issue has lasted over a year. Is that normal? He is in clean/dry boarding conditions (stays outside). I have also sanitized my brushes so that we don't reinfect him.
