DJ and LucyMascots

Meet Austin Equine’s mascots, DJ and Lucy. DJ (short for Dow Jones) was bred by Stock Market’s Miniature Donkeys in Dripping Springs. Our doctors saw him just days after his birth for a lameness evaluation (he was born without a navicular bone in his left foot), and was later given to us in hopes that we could give him the continued treatment he needs for this rare condition (he is sound and doing well). Though we all quickly bonded with DJ, he was lonely without a donkey friend so his breeder sent us Lucy (Loose Change) to be his companion. Yes, we got a donkey for our donkey. DJ and Lucy spend their days greeting patients in the barn, observing lameness exams, and eating Dr. Evans’ landscaping. They’re very friendly and love to follow people around in hopes of a good scratching…don’t be surprised if you see DJ or Lucy hanging out in the front office when you visit us!
