I suspect that you will hear all sorts of things about stallions and stallion lines, being this or that. I think a lot of it is pure baloney. As the OP alluded to, so much depends on what the owners do, from day one. For example, years ago we were told by those “in the know” that Lord Sinclair would produce difficult horses (one registry “expert” even took the time to call us and try to steer us away, to a stallion that it turned out later she owned). We ignored the “experts” and bred to Lord Sinclair twice. LOVE both offspring.
The one, Lord Baltimore – was Robin Brueckmann’s ride for a few years. Robin is a para Olympic rider for the USA. She rode without stirrups, and often used metal braces to assist her. Whatever else you could say about Timmy (a.k.a. Lord Baltimore) he was a lamb around Robin. She trained him to back out of a trailer (at horse shows) by simply releasing the butt bar and tugging on his tail. He was trained to stand “naked” by the side of the trailer while Robin took her time to tack him up. She even trained him to pee on command when she whistled. Robin had him so responsive to her, so gentle and kind, and so laid back, that in the end, you could argue that he did not have enough forward, and may even have come to hate his job. Whatever was the case, he was willing to accept what she taught him, and every bit of it was about self-restraint. No horse with at genetically “bad temperament” would have done what Timmy did for Robin. For the “know-it-alls” with all the info on what Lord Sinclair would produce, they could not have been more wrong.
While I think that some behaviors traits have a genetic component, I think that a good deal of a horse’s behavior is grounded in how we humans interact with them. When we fail to understand their language and their needs, they respond, and sometimes that response is difficult to deal with… but the horse is not innately this or that.
Currently we have a Sandro Hit stallion - Sandro D. Sandro D is coming seven. I am not saying that he walks on water, but he lives in a barn /farm with mares, and is a gentleman, very sensitive, and completely devoted to his trainer. He works on a snaffle, never has a chain on his nose, stands politely in cross ties, and in the wash stall, never calls out or drops out…and is generally about a good as a boy could be. Here are some photos and video of Sandro D at his first show, where he was Grand Champion (not a big deal, other than that he managed the show beautifully, which was the point for us). http://logresfarmpintowarmbloods.com/?page_id=12
We had Sandro D home with us for the first five years… he was always a gentleman… always willing to learn, always looking for ways to interact with us. At times he might get an idea that he was going to do this or that, but in the end he always came around to what we were asking of him. If anything, we had to adjust what we were asking, to a language that he understood.
