What type of shelter does wolves it need or make?

Wolves typically seek natural shelters such as dens, which are often created in caves, hollowed-out trees, or burrows dug into the ground. These dens provide protection for their young and serve as a safe resting place for the pack. During colder months, wolves may also use thick vegetation or snow for insulation and camouflage. Overall, their shelter needs are focused on safety, warmth, and proximity to hunting grounds.
