Does a horse with a broken leg have to be euthanised?
Horses end up as dog meat if you send them to a dog meat factory. They pay you. However, there are only one or two horse meat proccessing factorys and they are not allowed to kill horses. Actually, some horses even go for human consumption. Most horses (and other animals) are cremated and buried. Further more, a horse does not have to be put down, but it costs a lot of time and money and is often easier to put the horse out of its misery. Horses are active, heavy animals that stand on all four legs. While your horse can avoid putting much weight on a leg, it cannot do this for any period of time. Like you said, you can’t make a horses stay still and rest. Most horses are humanely enthuaised because their legs will not heal successfully. It will be a long, agnonizing wait for the horse and afterwards, the leg might not be any better than it was.
