I don't have a problem with other people using hobbles... though I've seen and heard of the 'introduction' of hobbles experience being pretty risky and the potential for them getting hurt is high.
One friend hobbles his horse on the front when tied at camp because she paws.
Another hobbled hers for while at pasture when a new horse was introduced who was a kicker.
So they were corrective. I don't think they eliminated either behavior, only lessened the amount of damage done.
I'm not sure why I ever would.
Maybe on Harley, but it won't be to avoid tying him to the trailer.
My son is here and we are discussing letting horses graze with the lead rope dragging. I know he hobbles his horses, and asked him if you could hobble one to let them graze, I've seen that done. He is telling me he uses hobbles to minimize movement on a young horses when tied up. He also told me he knows how to hobble one that won't stand for mounting. He can hobble one with the tail end reaching the saddle, mount the horse then pull the tail and it all comes off. I thought that was cool:)
He says the first time you hobble one put them in the middle of a big area, and keep an eye on them. He says he has never seen one fall. The ones he has seen, tried to walk around, then would hop around a bit then just stop. He does not leave them long loose with hobbles. He doesn not want them to learn they can walk around with them on. They are to minimize movement while the horse is tied up.
