Let's get to to idea of purchase........while I don't breed very many mares now (have many, nice mares, just don't breed! And nice correct stallions who get little
).....if you don't know your horse, know your breeder!!!
When I bought stallions I made it MY responsibility to see them in person, have a vet or a person who's eye I trusted totally, to see them -- or relied on a video that met MY criteria for replacement of visit, and/or had a guarantee of return for full refund "if" XYZ items exsisted.
When I sold, I expected to have the same hold true, if I was asked. There were persons who had vet checks, some not. My video was taken as if a judge were looking at this animal -- walk/trot forward and away (with tail UP & down), loose in a lunge venue, loose in a field, standing & walking from both sides, moved mane to both sides, head with & without halter, teeth, ears, eyes, hooves (up & down positions), genitalia and all that..........along with the stick measuring while watching and so on. Tried to make it just like they were live on the farm. Even squatted down to take video, not just standing!
My feeling is this -- if my animal is not up to par for their breeding, a buyer should have as much before them as necessary to make this determination. If it is not up to par for my own breeding, I won't buy. When I buy and just can NOT go in person, it is at a price that allows me to geld and sell.
Just as particular with my mares. In fact, I have had 2 mares purchased which I never bred after getting them home (although they had produced previously). One is still here, now 23 -- been fed and cared for at my farm for 15 years. Her body was tooo long for me. So, a babysitter she is! Shame we can't "geld" a mare, LOL -- the costs and issues with neutering them is not acceptable, so many get passed along & bred. The 2nd was sold to a known family, still there, a great pasture ornament! (Bad bite, hubby bid at auction of a great looking body and had not checked teeth!) I did not see either in prson before purchase, both were at auctions.......talk about buyer beware!....I almost never buy without "being" there -- see why?
People have VERY different ideas of what is/is not correct, pretty, nice, etc. This is where much of the issue will be, in an "opinion". And, as Becky has pointed out, some animals would not have issues if properly grown and cared for -- i.e. feeding, farrier, vet, etc. And injury can be an issue in a very few cases, which could affect "looks" and not genetics.
Buying and Selling is TOUGH!!
Homework on bloodlines that have known "issues" is needed. It is much harder for newbies.
