What is a horse's lifespan?
As with people, our pets are enjoying longer and healthier lives. With the right care and a little luck it is not unreasonable to expect your horse to live to thirty years old and beyond.
Most horses live for between 18 and 25 years. Horses that are exercised hard and strained when they are young often wear and die faster, around age 13 or 14. This is only likely to be the case with an Arabian if it was raised in Arabia or parts of Africa where horses are ridden and raced as yearlings. Horses will live longer if they are well cared for and given good nutrition.
This is called a barefoot horse, and it is healthier for the horse because horseshoes restrict bloodflow up and down the hoof, conduct cold into the leg and hoof, and sends vibrations up the horses leg, damaging tendons and joints. Horseshoes can and will actually shorten a horses lifespan. Domestic horses only live a fration as long as wild ones do. Horseshoes cause several more problems, as you can see in the related links below.
