Most of my pups have about 25% wolf blood by design. This has been part of my breeding strategy for many years and, contrary to popular opinion, the result is a less aggressive and hyper dog, on average, than the German Shepherd created by prolonged line breeding.
If you think about it, a wild canine will do everything in its power to avoid confrontation with humans under normal circumstances. There are three exceptions: Starvation, being cornered or protecting its young.
A wild canine is also generally smarter than a domestic one because of the natural selection process involving survival in the wild.
Over many years of breeding I have found that the wild genetics is highly beneficial in creating a great family companion.
