I have a yearling mini filly (will be 2 in April) that was born with an underdeveloped kneecap. She has learned to adapt to getting around on the 3 good legs, but does walk with a limp since the deformity doesn't allow her to fully pull up her leg. She's a sweetie and full of energy. We held off euthanasia because she is just so full of herself and has a love for life. She would be a good pet horse for someone who doesn't mind her bum leg. She enjoys her hay and pellets and likes scratches.
Due to the deformity, she isn't registered, but does come from registered parents.
