Do wolves in a pack sleep together?

Wolves in a pack often sleep together, usually huddled close to each other for warmth and a sense of security. Members of a wolf pack may sleep in shifts, with some remaining alert while others sleep. The pack's sleeping arrangements are typically organized based on rank and social structure. Dominant wolves, such as the pack's alpha pair, typically get to choose the most sheltered spot to sleep. Subordinate wolves may sleep near their higher-ranked pack members for protection and to maintain social bonds. Sleeping together also allows wolves to quickly mobilize and respond to potential threats or changes in their surroundings.
