A bit of background, for those who don’t know…
In November of 2009, my rabbit, Mr. Bunny, started getting large, rashy bald spots on his head. He had various tests and was diagnosed with fur mites. He got 3 doses of Ivermectin and the problem seemed to clear up; the bald spots grew new fur and his skin went back to normal. However, several weeks later he got a few new bald spots. He got 3 more doses of Ivermectin (the most recent one given yesterday), this time with a much stronger dose.
Over the last few days, he’s been getting even more bald spots. They aren’t rashy so far, but he has more now than he ever had at a time before. There’s a smallish one between his ears, another small one at the base of his right ear, a couple of fairly large (dime size?) ones on his side (the first ones to be somewhere besides his head) and now a really big one all along his right cheek.
The vet says that if he’s still getting bald spots in a week or two, he’ll take a skin biopsy and refer us to a specialist.
Has anyone dealt with fur mites that keep coming back and coming back like these? What did you do about it? He’s had this problem for so long, it’s getting irritating.
