We finally found a horse that we're all really interested in for my daughter for 4-H, an 11 year old Foundation QH mare. She has been a barrel horse, done tons of different trail stuff, done some cow work, and acts like she'd prefer to be a pleasure horse. She's absolutely beautiful, she and my daughter really hit it off, and she performed better for my 10 year old daughter than her owner.
The catch is she's got Type 2 PSSM (EPSM). It has been well managed by changing her diet and stretches. I've done a lot of research and think I understand the disorder a bit, but I can't seem to find a lot of info about longevity. If it's managed well, does your average horse have the ability to be ridden for most of their life? Would you run from this horse fast, or give her a shot?
