He has pretty bad fetlock arthritis. His previous owner broke him in at 15 months, never did anything about him being toed in, and then barrel raced him from 2 years old til he was 5, until he could barely walk. My vet was called to euthanize him, but he instead talked the owner into giving Harley to him, and then he gave Harley to me. Harley was on stall rest for 2 months, followed by another 4 months of pasture to stop limping.
He's lived with me for the last 5 years and we just celebrated his 10th birthday.
He can only be used as a walk/trot trail horse, but he has a forever home with me so long as he's pasture sound. If he can't walk comfortably I'll PTS but until then we do what we can.
He's the main reason I fire farriers. Most farriers have no patience for him. He needs a very frequent breaks, but most farriers want to rush through the trim, and don't give him breaks. He's a total doll, as long as he gets his breaks. Keeping his fetlock bent on the stand is very uncomfortable with him.
Don't get me started on how many farriers have told me they can "fix" his legs with these 500 dollar shoes. Yes, your shoeing ability is going to magically straighten a 10 year old horses legs, especially since the bone is crooked from the knee down.
