I suppose the blood plays a major roll in how the dogs act as I'm sure some ppl have females that are just an animal hell bent on destruction even in the home. But my experience with my own is that the females are just much more dynamic. They can be outside on the yard and be a dog n wild as hell but come in the house and be as docile as ever. We joke that the males are dumbasses but they are not dumb but just not as attentive and are GO GO GO and just wild animals all the time, hard headed. Age plays a big role with them and not so much the females. I've never been bitten by a female though, of any breed. Always young males.
