*Why do we specify this? It's not that we don't like these lines. We do, in fact. So much so, that many of our mares carry these lines. However, like ALL purebred breeds, walking horses have been linebred in order to solidify certain traits (in their case, gait.) While you increase the likelihood of the gait being bred in, you can also increase the likelihood of genetic defects showing up and a certain amount of genetic variation is actually desirable. (Think European Royal families...they have...issues.) You create healthier horses with stronger more robust immune systems by utilizing family lines that aren't so closely related. Hence our notes. So if you have a mare who has a LOT of Pride's Generator breeding and you're looking for an outcross - Gambler and Handsome fit the bill. If you have a whole lot of Jose breeding in your mare, all four of our boys give you a nice outcross. And so on.
