I must address the issue that is becoming a popular belief at present, that boots cause tendon and ligament damage.
I am a strong believer that if you hear something DO NOT ACCEPT THIS AS GOSPEL, I question everything, as my friends and family will vouch for, much to their frustration.
You are intelligent and you are your horse’s guardian as he cannot speak for himself.
This is my thoughts on the issue, and again, just my thoughts, you must make up your own mind.
Definitely, if boots or bandages are not fitted correctly, they will cause issues and are a form of cruelty. But heat does not cause cell breakdown unless excessive. If this were the case, runners would not wear socks or use pressure bandages.
Many athletes, or avid gym users, wear lots of clothes on purpose to lose weight. If they risked tendon and ligament cell damage they definitely would not do it. Also, if this were the case, the horse’s back would be breaking down constantly as this is always covered, and contains many tendons and ligaments that are in constant high pressure.
When a horse does any kind of competition, it is put under extreme strain, accidents easily happen, maybe just getting to the jump too close or finding a dip in the ground.
We have put big metal shoes on our horse’s feet, and it is so easy for him to just bang his hoof on to the other leg, very often bruising it, which we are oblivious to because of the hair covering it.
There have been studies that have shown that there is heat created by these boots that could mean the tendons and ligaments become more stretchy, but in the studies I have looked into, no extra sprains or strains were seen as a result.
I would much rather protect the leg from blows and bruising than some heat.
As I said this is my thoughts but you must investigate with an open mind and common sense and make up your own mind.
