I paid $1,000 because I didn't think my niece would be able to sell him and she needed the money. He had had fluid drained off his hock before he came and the vet said that given the sandy area of the islands, it might never happen again. I've had no problems with swelling hocks. But the fetlock joint is half again larger then it should be. It doesn't seem to be fluid and it doesn't seem to bother him, though he does frequently change his resting foot, I find.
I agree that his tendons and ligaments must be under tremendous strain. Personally, I don't give him a long life expectancy. The vet haven't given me a prognoses and I don't think any of his previous vets have given theirs. At least none that followed him. He has had at least four owners before me. If I can give him a comfortable and contented life, that is the most important I can do. He won't be put down for this, unless the foot gives out completely.
I am so pleased that people her agree that shoeing won't help. It would be very expensive for me to ship him off islands for special shoes. His hooves grow incredibly fast. I've had 45 horses and I've never had to trim their hooves every couple of weeks. His should be done every week.
