Thank you everyone! That is very helpful. I just felt bad for this guy, he's a sweet horse and he's already 14, he's given his life to people and worked hard, and now he is just being discarded. I wanted to just take him where he would be comfortable and safe and loved. I don't mind if he will never be rideable, I'm prepared to just keep him as a pet. If my vet eventually thinks he can do some light trails, I might use him as a mount for my daughter, but I'm not taking him as a riding horse. He just really stole my heart. Supposedly, the owner had a vet come out when he was first injured and "the vet thought he would be okay", but to my knowledge there wasn't much of an exam, certainly not x-rays or anything like that. He doesn't seem to be in pain, he eats well and runs with the other horses in the pasture. My hope is to re-hab enough that he can have a comfortable life and not need to be put down just because his former humans didn't give him proper care. My first task will be to call my vet out. Fortunately I live very close to the UCDavis vet school and we have some world class vets and access to excellent treatment in this area, so I am hoping he will be okay. :) Thanks!!
The basest horn of his hoof is more musical than the pipe of Hermes.
He's of the color of the nutmeg and of the heart of the ginger.
His neigh is like the bidding of a monarch,
And his countenance enforces homage.
- William Shakespeare
