It stayed like this fair a while and now its obvious he has been rubbing it. I've bathing him and applying a stop itch treatment for a few weeks now and that hasnt worked. He is even rubbing his tail now :( his beautiful mane and tail are getting trashed. I don't know why he is itching. There is nothing visible on the skin and no flakes or anything that would indicate why he is doing it.
I've tried a few different stop itch treatments that have worked in the past but nothing is stopping him.
