6. They Play With Energy and Interest
Playfulness is a huge sign of a happy dog. Whether they’re chasing a ball, tossing a toy, or zooming around the yard, energetic play usually means they’re feeling great. Dr. Bekoff’s studies on play behavior show that dogs use play not only for fun but also for social bonding and emotional expression. He explains that happy dogs often initiate play with humans or other animals using specific body signals, like the play bow or exaggerated movements. When a dog invites you to play, it means they trust you and enjoy your company. Play can also boost positive emotion by triggering dopamine, the brain’s “reward” chemical. So if your dog keeps bringing you toys or playfully pounces on a stick, they’re sharing their joy.
