Are Dogs Playing or Fighting? How to Evaluate Rough Play

If two dogs are wrestling and it seems too rough to you, with all that growling and snarling, body-slamming, and biting of each other’s necks, should you intervene? How can you tell if dogs are playing or fighting?

This is normal dog play. Puppies play with their littermates constantly. From around two weeks, when their eyes open, until they go to their own homes, they spend almost all of their waking hours wrestling with each other. It’s a critical time for social development because it is when they learn bite inhibition and good dog manners. It is good exercise and socialization for them and fun for us to watch. But you should learn how to tell the difference between playing and a real fight when adult dogs are involved.
