I suspect that as veterinary medicine has progressed, we know more.
It isnāt that there are more unsound horses than previously. It is that now we find out what has been going on with horses all along.
Horses some time ago had all the same issues. We didnāt know it, because a) we werenāt looking and b) we didnāt have a way to look.
And it was unfortunately customary to attribute many of the symptoms to behavior problems. It was a change of mindset to think that a behavior was a reaction to something internal, rather than equine oppositional defiance.
It makes me very sad to think of all the horses put into brutal training programs because they were reacting to spine issues that we couldnāt diagnose in those days.
Now we have to figure out how to make these horses more well and healthy. They can enjoy life, and so can their owners.
