I think it is the worst possible place you could think of to buy a husband horse! My local low end auction has horses go through all the time that are advertised as safe. If you’re lucky you can see someone ride them in the parking lot. You can’t ride them yourself, you can’t vet them, you can’t do a drug test, etc. There is a horse right now on that website that ran through the same auction 30 days before as unbroke, a different age, and a different breed.
Dealers purchase horses, put an intense and overwhelming 30 days on them, hit them with a bit of bute and some ace, and voila they are broke to ride.
A local dealer picks them up and they are on his website in 24 hours flat for sale for double what he paid with a “this horse is safe for anyone to ride.” He has no actual idea if any of this is true.
Auctions are good places to get cheap horses if you know what you are doing, know what to look for, and can accept what you get if the horse ends up being dangerous or lame. Rescues that work with auctions want you to believe you are getting the next husband horse when you are just as likely to be buying someone else’s problem. Not every horse purchased at an auction ends up winning at Devon.
