One of my piggies, Hope, has had issues with losing hair ever since I adopted her four years ago. I have been to four different vets (including a vet for exotics) and spent hundreds of dollars, but nothing seems to help and in the end the vets say they don't really know what is wrong. She has had several rounds of treatment with ivermectin, treatment for ringworm, treatment with a medicated shampoo, and some kind of spot-on treatment for cats (I don't remember which one, this was several years ago). She doen't have any bald patches, she just looses a lot of hair, mostly from her back and rear end. The hair falls out with what looks like little scabs attached at the base. She doesn't act itchy at all, she just loses a lot of hair like this when I brush her every week. My other two piggies are healthy and don't have any of these symptoms. One vet thought it could be something he called sebhorrea and told me to bath her often in a medicated shampoo. The baths seemed to help a little, but she hates them so much that I try not to do them very often. I'm pretty sure she is a rex/teddy breed pig, and I've heard that they can be prone to skin problems, do you think this could be it? I have tried different types of bedding over the years incase there was an allergy there, but none of them seemed to make any difference. I currently use a layer of Yesterday's News covered with a layer of Aspen, but I have also tried Carefresh, Yesterday's News alone, and Woody Pet. She eats unlimited Timothy hay with Oxbow timothy pellets and veggies every day. Does anyone have any ideas or suggestions?
