No, gray wolves do not typically live in burrows. They usually make their dens in underground burrows, caves, or sheltered areas, but they do not live in burrows on a permanent basis like some other animals. Wolves may use burrows for shelter or to raise their pups, but they do not reside in them year-round.
Their defense - is to literally 'run' backwards - driving sharp quills into their attacker.
they use acoustics to identify wolves by their howls
They use it when someone diturbs them as a defence mechanism and then the skunk gets away when its predator is disturbed... :)
