I'm helping out my grandma who isn't at all tech savvy. She wants to possibly find a fly sheet for her standard jenny. Every summer the donkey rubs her face and chest just about raw because of either allergies or flies. They've been to the vet, been on steroids, tried numerous topical things, and nothing seems to help. A fly sheet and mask might work and help stop the itching. I just don't think they make those sheets for donkeys. I guess you'd just measure the donkey and order that size? It'd be closer to a pony size if anything.
