I don't think the attitude is a gender issue. It is more the individual dog or dog's family. Temperament and attitude is unbelievably heritable. That's why we breed certain lines for herding or performance. But its also why my rescue handled several vicious dog cases that were all progeny of one widely-used Champion stud dog. Since the attitude question was framed in the context of using him as a father, I would think about it. Stubborn isn't as much fun as not-stubborn. Biddable IS better.

One year old Liam is an "intense" dog when he is herding who stands his ground on the sheep. But he lets the cats beat him and chase him and he just lays down and squints his eyes. He is super friendly to everyone and every dog - even the little corgi girl in the pet store that snarled in his face.
His attitude is whatever the game, we'll play. He is exactly the temperament would breed for if I were a Corgi breeder but he has the poorest front I've ever seen, came from the rescue, and thankfully is neutered.

I know we're a little off thread about the mix-breed breeding topic but I agree with the others that we can't just breed more dogs, we must breed better dogs. It's not just mixed or purebred question. There are bad purebreds and great mixed breds. Anyone thinking of breeding (assuming they aren't keeping all the puppies for their entire lives), should be aware if animal overpopulation is a problem in their area. In US, especially in California, it's a huge problem. Anyone thinking of breeding a litter should visit a shelter and watch a "bump" (kill) list. Even if one doesn't watch them kill them, just watching them remove the dogs from the runs and realizing that the dogs know what is happening will break your heart.
