I have had my mare for two and a half years now, but ever since this winter there have been two wierd patches of hair on her. They are right where the saddle pad ends on her back (western) and off to the sides. The skin underneath is healthy, the hair isn't matted or overly dirty, but the hair is shorter and lighter than the rest of her coat. I've tried grooming it out, washing her, but can't get rid of it. If anybody knows what is causing this I would be happy to know.
Additional details about my mare:
Yes she is a healthy horse and I don't think its a fungus. She was wormed recently. She is up to date on all vaccinations. She was not bred,(sometimes horses get wierd when they are), she has not ever had a change of diet while we've had her. She has been in the same stall for a long time. She has not had contact with any horses lately. She has never had anything like this before.
