We had a husky that was knocked up by a WOLF.
Huge animals. Would hunt anything that wasn’t a person, cattle, horse, another canine, or a housecat (they loved our cat). Very friendly to family.
Absolutely worthless guard animals. They would literally sleep through anything unless roused by a yellow ranch dog(which would get them going — after about 5 minutes).
All wolf mixes generally fail as guard animals.
They have no natural predators (typically) and so never really remain alert.
You’re lucky yours were well behaved. The ones I’ve dealt with have a serious dominance thing going on and needed far too firm a hand than I like to give an animal. Plus they’d do things like run off and kill neighbors’ animals.
