Tell me about your "long term" experience with them? I will possibly be adopting a horse that retired from the track with one. This was 2 years ago. Anything I need to know now, since he has already had time off and been started retraining to be adopted out?
When I say "retraining" I mean basics and desensitizing, no hard work.
I would ultrasound it to see how much scar tissue is present. If minimal, the horse may stay sound competitive, if legged up properly. If there is a lot of scar tissue, probably a trail horse.
We use good wraps (favorite are classic equine) wrapped properly or PROPERLY applied polos when exercising and 3 degree shoes to continually support the tendons.
My off the track Standardbred bowed a tendon many years ago. He recovered and went back to the track and raced for several more years. I adopted him a couple months ago after his last career race as a 12 year old. I trail ride him now and he is completely sound. He needed corrective shoes for racing but I trail ride him barefoot without any issues.
