The desire of many dogs to crawl under the covers may be an ancestral trait left over from when dogs were often born in dens. Being in a den or cave-like atmosphere may provide a sense of comfort and security for them. For some dogs, crawling under the covers may be a common occurrence. For others, they only do it when they are anxious (such as during a storm) or not feeling well. Dogs may also crawl under the covers with their people because they enjoy the warmth and companionship of being snuggled up next to their “human pack”. This behavior is more common in some breeds than in others. If your dog likes to crawl under the covers, be sure it has an easy way to get out should it become hot or anxious.
