Yes
No you have to train a horse how to jump over logs+jumps, Not all horses are made for jumping horses!
You can jump in training, but typically endurance horses are taught to step over obstacles instead of jumping them. Though they may have to jump something that is too high to step over.
It generally is, yes. Left to their own designs, horses will commonly jump over obstacles in their way. But some show a much higher preference for it than others - they are then trained to become expert jumpers.
All horses can jump.
yes, and it's called free jumping
by bending their legs and its natural they just know either their will jump or crash... --this is true-- The same way people jump.They jump by cantering towards the jump. Horses rely mainly on you, so you stand in the stirrups. the horse will lift off, and you sail over. Careful, though, as if you gallop, your horse will approach too fast, and all the weight will come crashing down on his legs as he stumbles. This can break a horses leg. Horses are able to trot-jump, too. Horses eventually learn by the fact that "Oh my gosh I cant go around it! Oh my gosh I cant go through it! And wow i can go over it!" Most ponies are taught to tuck their legs under by when they go over it the people on the other sides of the jumps raise it to bump them as they go over it. Horses learn just like us!
