Mouth Wrestling "Bitey face" or jaw sparring

 My dogs love to mouth wrestle. They wag their tails and play bite each others faces.

Mouth Wrestling "Bitey face" or jaw sparring is a normal, healthy, and common form of play in which dogs grab at each other's faces and necks with open mouths, often accompanied by soft growling and bobbing movements. It acts as a bonding activity and allows dogs to practice bite inhibition and social skills, rather than actual fighting. 

Why Dogs Do It

• Social Play & Bonding: This behavior strengthens social bonds and is a natural way to communicate and bond with other dogs.
• Practicing Skills: It is an instinctual form of "play fighting" that allows dogs to practice fighting skills safely without inflicting real harm.
• Safe Rough Housing: Although it may look intense to humans, it is generally harmless, as the biting is not serious. 

How to Tell if It's Play or Fighting

• Loose Body Language: Dogs will appear, loose, wiggly, and relaxed in their movement.
• Turn-Taking: The dogs will often trade roles, with each getting a turn to "win" or hold the other's muzzle.
• Open Mouths/Soft Growls: The play involves relaxed, open mouths (sometimes showing teeth) and relaxed ears.
• Constant Re-engagement: If they stop for a second, both dogs will quickly try to return to the play. 

When to Intervene

• Bullying: If one dog is trying to escape or does not reciprocate the play, the other may be bullying them.
• Tense Behavior: If the dogs' bodies become stiff, the growls become deep and guttural, or the action is not matched (one dog is too intense), it may be time for a break.
