Whether the 40 be years, or 40 dogs, I respect the experience, however, the research by both Green and Coppinger found hybrids between LGD breeds were overall more successful than the purebreds. Fighting between LGDs is not uncommon, be it for dominance, or sex, regardless of purebred or hybrid. My more serious fights have been among purebred dogs, but I think that is because my intact males and females are usually purebred, and the neutered males and females are usually hybrid. i.e. sexual status is the problem, not purebred vs crossbred.
