Sorry to bother anyone if this has been posted before and I have tried using the search without an answer. I'm thinking of buying a Red Dun mare that is seven years old and has tested positive for pssm. It is controlled through diet and exercise and has not exhibited any effects from it. I have talked to the vets but one of the vets is a best friend and other is related but they were both forthcoming with all the information on this horse. That being said I wasn't that worried about it because I would use the same vets. The mares records were open/released to me without a problem. The horse has been trained in Reining and has competed at the local level. The horse is also used for pleasure trail riding and working cattle. My duaghter is thinking of doing some Reining and currently competes in western pleasure. So the horse has some of the skills we need. I'm just wondering what a price reduction is warranted for the PSSM or even if it is warranted? I know the chance I'm taking and even myself not 100% sure if the chance is worth it. But if the price is right. Thoughts? Thanks.
