It is a sad fact that there are cruel idiots everywhere, but to tar an entire industry with the same brush is just narrow minded. I know a lot of horse people who go above and beyond for their own horses and horses that aren't theirs. They do not condone nor accept abuse of animals be it from an elite professional, a trainer or a person down the road.
I've worked in the racing industry, I'll admit I don't agree with every practice, such as the racing age, but these horses are very well looked after. Some retired horses, and these race horses retire young, are even kept on for the rest of their lives by the trainer. I don't see any 'personal gain' in that. Horses aren't cheap!
The main thing I am rather over hearing is that 'the horse does all the work'. Please. Ride a horse properly for an hour and tell me you're not sore the next day. It takes a great deal of fitness, core strength, arm strength, leg strength not to mention mental strength to get a horse fit and working properly. Yep horses do work hard, but if they aren't capable or enjoying it trust me they show you the signs!
As for giving the horse the medal. A horse couldn't give a crap about a medal. A horse cares about food.
I've had horses for 15 years and I've never once thought of it as 'personal gain'. I think people miss the point that these are domesticated animals, they are bred for purpose ( the responsible breeding anyway), they aren't the wild brumbies or mustangs cruising the outback being able to fend for themselves. And whilst my horses are retired now, they loved being ridden, going for a gallop, being on the games team, the dressage team, the jumping team, and they won many ribbons and trophies in their careers, not that they'd even realise.
You need to actually get out there, put yourself out and experience what it is that trainers and riders go through with their horses instead of sitting on here criticizing and condemning them of being cruel. Research, discover, talk to people who actually KNOW and find out the why's and how's. Or sit back and say 'I hate it just because' and learn nothing.
