How many people decrying what others choose to have in their horses have a short legged, long backed dwarfish dog, with the problems that brings and think that is fine?
People breed and have the animals they have because, for them, that is what they want in their animals.
I don’t know about that one straight legged one, I have not seen that so much that overly, practically double muscled halter horses that look deformed, like a Hulk in a horse suit.
Yes, Hulk looks deformed also, compared with a normally muscled human.
That quarter horses can be so different is exactly why they are called the versatile breed, you can find some that will fit most anything anyone wants to do with horses.
Remember, the more someone restricts any breed of animal, any genetic pool, the less those animals will thrive.
Some of the extremes can end up there, that is why people cross breeds.
In quarter horses, you can do that within the breed.
Two of the horses I have are at home and are very different in how they look and move, both AQHA.
One is a high performance bred, trained for years as a reiner, just not talented enough, turned into a ranch horse.
Still, he can move around carrying himself beautifully, he was bred to be that kind of athlete.
The other, I got him for company to the first one, is ranch bred and is an excellent ranch horse and arena team roping horse, both ends.
He moves like a car with square wheels, doesn’t really know how to use himself properly and does what he does, compared with the other horse, almost in slow motion and in a more jerky, forced way.
With some careful training he is learning more how to be easy on himself, but it is not bred in him, as it is in the previous horse.
He is the equivalent as a human learning to dance but has by nature “two left feet”, is just not going to compare with the one born to move in space light and correct.
Both have the wonderful, full of try and kind and easygoing personality quarter horses are generally known for and none are on any extreme of conformation, many/most quarter horses are not.
