I took my B in to the vet last week due to a dry patch on her hind quarter. We thought it may be due to the weather however it didn't seem to be going away and then it seemed like it was getting worse. We found out after a skin scraping that it was demodicosis. I type of mite that lives in most dogs. The problem being that she has a hereditary immune deficiency and can't ward them off naturally. Thankfully it's just a localized form and not a generalized form so it should be treatable. However she seems to be getting another mild one next to it. I'm a little worried that it is a generalized form and it's just now breaking out.
Anyone ever had any experience with this? She has always been on a 'Natural Balance' diet which is a good meat based food and we give her suppliments that are high in fatty acids and omega 3 which was recommended.
