I would suggest asking you're vet that question. That would depend on the severity of the injury and how well it healed.
A horse's Check Ligament runs along the back of the leg and is most frequently injured when a horse lands a jump or steps wrong resulting in a strain of the ligament.
if the injury is completely healed and isn't causing the horse any pain the yes horses can still jump after a fetlock injury.
An Anterior Cruciate Ligament tear is a serious injury taking place during sports often times when pivoting or landing from a jump
Non-contact injuries, often occurring during activities involving sudden change in direction, abrupt stopping, or landing from a jump, are the most common causes of anterior cruciate ligament (ACL) injuries. These injuries can happen in sports like soccer, basketball, and skiing.
if your horse refuses the jump, you turn the horse around in a circle, then go a little ways away from the jump, (but not too far giving the horse time to think about how to get away with going over the jump) and then (if the jump is not too large) trot your horse over the jump giving it leg pressure up to the jump to coax it to jump. (its easier to trot over the jump than canter when your horse doesn't want to jump it) if your horse refuses a jump during a show, this will count down points but if your horse refuses a few times you are disqualified. hope that helps!
yes any breed or type of horse can jump, how well they jump depends on how well the horse was trained.
If there is an issue where your horse comes up lame while jumping then you need to have the vet out to take a look at the horse to see what the issue is. Not all horses are capable of jumping as it puts enormous strain on their tendons, ligaments, muscles and bones. Your horse may have an old injury that will not allow it to jump, or to jump as much as you would like to. In any case if the horse comes up lame repeatedly then you likely will not be able to use that horse for jumping any longer.
Spooking does not matter hoe high a horse can jump. If a horse has jumped over fences and has been trained you will be able to have your horse jump higher in competition.
When a horse scopes out a jump, it just means that the horse is looking at the jump trying to get a good idea of how tall/long it is and where they have to take off in order to be able to clear the jump.
Well that will vary from horse to horse no matter how good the training. The best way to find out is to free jump the horse and continue to raise the jump until it's clear how high the horse can jump without problems.
I have never heard of a horse jump 13 feet. The highest I know of was 8 feet.
