Growing up, my grandpa always had wolves. They required a lot of attention but they were great pets. The problem is wolves don't bark. If they are raised with dogs, they might adopt a low "woof" noise but not a alarming bark. For one of his wolves, if she sensed someone driving up the road, she would move closer to grandpa and touch him with her nose, and never make a sound. Her son (who was a big boy) on the other hand would move up the hill to a sensory position, again completely silently. If cornered they'd probably fuck you up, but if you trespassed, they'd probably just watch you from a distance. Now my grandpa, as confirmed to me by multiple people, would shoot at you, so the wolves were the least concern.
