5. They Sleep Soundly and Often
Dogs sleep a lot when they’re happy and healthy. On average, adult dogs sleep 12 to 14 hours per day, and puppies sleep even more. According to research in Frontiers in Psychology, relaxed, consistent sleep is a strong indicator of emotional stability in dogs. A dog that naps peacefully in your presence feels safe and secure in their environment. Dr. Marc Bekoff notes that emotional well-being is linked to restful behavior. Dogs under stress may pace, whine, or have restless sleep. You can tell your dog is content when they snooze in familiar spots, especially if they sleep belly-up or with their limbs stretched out. These positions show complete trust. A calm, sleepy dog is often a very happy one.
