There may be several reasons why dogs like to lie down: 1. Comfort: Like people, dogs also need to rest. When they lie down, they can relax the body and relieve fatigue. 2. Temperature: Dogs have a higher body temperature than humans. Lying down can help them dissipate heat and maintain body temperature.
3. Sense of security: Lying down can also make your dog feel safer. In the wild or unfamiliar surroundings, lying down can provide a better view and the opportunity to observe your surroundings. 4. Pain relief: If your dog is uncomfortable or in pain, lying down can relieve the pain. All in all, lying down is a natural behavior for dogs that brings comfort and security.
