My rabbit had a small patch of hair missing on the back of her neck basically ever since we got her. We got worried when this started getting bigger so about a year ago we took her to the vets. Twice. We spent £66 in total for the vet to tell us they don't know what's wrong as apart from the hair loss the rabbit's skin and overall health were in pristine condition. However, the hair loss just continued to the point where most of my rabbit's neck is now completely bald. Recently I have noticed what looks like dandruff in her fur and so I researched walking dandruff however I have never seen the dandruff actually move. I was just wondering if there could be any negative effects if I treat her for walking dandruff (with a treatment from amazon) even if she doesn't actually have it. Also are there any home remedies for walking dandruff or just hair loss in general? I have attached pictures of what her neck looks like. Any help would be appreciated, thank you.
