toed in barrel horse?

My barn owner has given me one of his horses to run barrels on. He bought her from someone who had trained her for barrels but claimed she wasn't fast enough for what she wanted. She is toed in, and both him and many others are sure that this won't affect her at all. She has a really wide wide chest so her legs don't hit at all, but I have been doing some research and I heard this can be very hard on their legs and they can become lame very easily. I was just wondering what everyone thinks of this, because she runs around the field just fine and when I have had her loping in the round pen she seemed ok.

Is she slightly toed in, or is it really bad?

If its only slightly she should be fine, not even the most expensive horses have PERFECT confirmation.

I agree that it would depend on the severity of the fault. Though being pigeon toed does predispose them to problems like ringbone and sidebone (and some say navicular), I have a horse that is very pigeon toed that I have been using hard for about 5 years now, he's 8 years old, and he has never taken a lame step in his life. I think with proper care and preparation, she would do just fine. Though she may never run terribly fast because pigeon toes make them paddle and it takes more time and energy to get their feet from A to B.

My mare toes in, we werent going to buy her because the vet said not too because she would probably go lame in two years. But we bought her, and she hasnt ever been lame. I've heard its kinda a hit and miss. Some horses go lame permaently if they toe in, some horses go their whole lives toeing in with no problems. I must say, having a great farrier helps!
