A while back there was a discussion about using horse wormer cream with Ivomec on a dog's elbows to clear up callus spots. The argument was that the spots were areas where demodectic mites had taken over and the horse wormer with Ivomec would kill those mites and allow hair to regrow.
We've had a couple of recent posts about bare spots, demodectic mange, etc. Has anyone tried using Ivomec horse wormer cream for those isolated spots? Did it work?
