Ah yes but some disciplines are actually a major threat to my horses. I used to love competing in WP, and I still excersize my trainer's WP horses. But I refuse to breed or compete myself because I feel very strongly about this matter and the seriousness of the horse health. I know every sport has risks, and every sport has a chance of the horse going lame, but IME this sport is what has broken down and ruined most of my horses since the not-so-new head position and lurching. I had a filly who got a spinal problem from WP and she had to be put down because they couldn't save her. The vets all told me that it was because of her head being so low that she caused her own spinal injury. I was very close to that filly and she was one of the last foals out of my favorite stud horse who also died last year.
Not that I expect any of you to take my advice, because I'm most certainly not going to take anyone else's either. But I figure I'll share my experiences and offer an explanation as to why
I feel this way.
