even if the horses are treated well they all face a similar fate, at the end of the day the racing industry is all about money, and tens of thousands or horses are bred each year in the search for a fast horse that will win races and earn alot of money for their owners and trainers. obviously most of the horses that are bred are not fast enough or they are injured or no longer useful, then they are sent to the knackery or even worse they are sent to horse sales which are extremely stressful environments to THEN be trucked for hours on end, where they are transported to slaughterhouses and killed. it is a very cruel industry!!!!
All horses face a similar fate? I wouldn't say that's true...
I'm not sure how much you know about horses or riding but nearly all of my friends have ex race horses. They make great all round horses! I have a standardbred ( a ex pacer) and he is absolutely beautiful and i love him to pieces. So not all of them end up in bad situations.
It's like saying all 100 sheep in my friends paddock must be there because they are going to end up in a slaughter house but they are my friends extended family and she knows every one of them by name.
I am not trying to be nasty or anything but the same can be said about so many things but it is not always the case.
When i first left school i did stable hand work and my mum use to be a strapper and save horses from ending up in a tin. I'm not saying it's a perfect industry and i'm not saying i am for everything that happens but not all of them end up in bad situations like you have said they do.
