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. There are different physical cues that signal that dogs are playing. If they have a big, silly, open-mouthed grin, that’s already a good start. Often, their movements will be exaggerated: bouncy movements, and even exaggerated growling. Dogs may do the “play bow” when playing, where their front end is down, and back end is in the air. Dogs who are play-growling are over-exaggerating their snarls, which may make this noise sound scarier than if they were actually fighting. If dogs voluntarily make themselves vulnerable by “falling” down, they’re probably playing. Playing dogs will allow themselves to be caught while playing chase, and take turns chasing each other. Dogs who are playing will keep circling back from more.
Dog play and dog fighting can sometimes look similar, but there are tell-tale signs to differentiate between them. Dog’s bodies when they’re upset or feel threatened by another dogs will become very stiff. Their hackles, which is the hair on their upper backs, are raised. If your dog has long hair, this may be harder to spot. Their growls will be different too. They will have low warning growls, closed mouths, and curled lips. Their ears will be pinned flat — no big, silly smiles. Dogs are trying to get away from one another, or at least one probably is, and their body language reflects that. They won’t be happy and bouncy. Instead, their tail may also be tucked underneath them. A dog that feels threatened will have quick and efficient movements. They won’t be bouncing around, and definitely won’t be “taking turns” like they did when they were playing.
