My roommate is going to be taking our neighbors 9 year old Percheron mare this spring as they can no longer care for her. This mare is perfectly healthy except for one thing, she has no mane or tail. According to the neighbor the vet couldn't find anything wrong with her including worms, mites, ect. She literally looks like someone shaved her mane and tail off. Does anyone know what this is? The rest of the neighbors horses have perfect manes and tails. They got this made like this and it never grew back.
