Horses are living breathing thinking and feeling animals. Of COURSE they care. The difference is, training a horse and bettering it and making it more suitable so someone will be more apt to KEEP it instead of just buying a horse to play around with for nothing but your own selfish gain and then throwing it away when you get bored. Not fair to the horse. But people like you who think horses are mere livestock and that they have no feelings and that the only thing keeping them satisfied is food shouldn't HAVE horses.
Cows have feelings. So do cockroaches for that matter. All beings are capable of feelings. Well, not so sure about some humans, now that I think about it.
Some horses are more in tune with their humans. Others are not, in fact I would say that most ARE satisfied with being fed, and couldn't care less about being ridden, or even eyeballed, as long as the feed is coming regularly.
Telling someone they shouldn't have horses because they view them as livestock? Please.
Like it or not, horses are expensive. For someone that can only afford one horse, if they are wanting to trail ride and their horse has gotten too old, is lame, or is unsuitable? Are they to keep that horse for 20 or more years then? Never be able to go riding because they can't afford to keep another one they can use? The market for lame horses is pretty slim. Same with one that is actively trying to kill you.
While my two older horses and the new one will have a home with me for life, that is MY decision. I actually made it 10 years ago or more in the case of Bonanza and Kola..and will PTS when time is right.
People buy horses, train horses, sell horses, that is just the way it is. Even with best training in world, horses go lame, or just aren't going to work out. According to the way you seem to think, those horses are to be kept forever? How many can you afford to do that way?
And as long as there are idiots who keep breeding horses because "they wanted a cute little foal, and Joe down the road had a stud, so we bred my mare to him" there are going to be plenty of unwanted, unbroke, scruffy grade horses.
And most of those people? Don't seem to understand how to go out and feed the horses they have in their yards.
Maybe if working Americans weren't forced to support so many deadbeats and their families? There would be more money for horse sanctuaries...I know I'm tired of watching my tax dollars go to take care of multi-generational mooches.
Not all horses can be trained. Not all horses are suitable for a beginner, nor will they ever be. Not all horses will stay sound.
