Mange

[davard]

I'm pretty sure my horse has sarcoptes mange.
Does anyone know how to treat it? I've heard ivermectin will treat but I don't know how often I need to give it to her.. Her poor head is full of sores where she has rubbed and it is now spreading to her neck

Several years ago I thought that my horse m igh thave contracted sarcoptic mange from a sick fox which slept in my barn.She had bald patches and was scratching herself at every opportunity.
I called my vet who told me before visiting that it was extremely unlikely to be mange. He diagnosed rain scald ( due to over rugging a damp horse) but also administered a Dectomax injection. The bare and weepy patches cleared up after dabbing with diluted Hibiscrub. The problem has never reoccured but I did invest in a Mark Todd Coolex rug which I always use to ensure that the horse is completely dry before putting a turnout rug on. By the way the patches where the hair fell out were all on areas covered by her rug.

In your position I would get the vet sooner rather than later.
