When is play too rough? How can you tell the difference between bullying and play? Dogs play mildly imitates dogs fighting. Dogs give very clear indicators to each other when their intentions are aggressive, but we misinterpret or completely miss these signals very often. Some of the most common misread signals are piloerection (raising of the hackles along the back), neck biting and growling. People often think these are instant signals of aggression. Unfortunately, they can be both play or aggression. The best way to discern the intent of a dog is to observe the overall tension of the dog. Is the dog stiff, rigid, leaning forward with locked knees standing as tall as possible? If so, walk away! However, if the dog is loose, wiggly, bouncing around erratically, their motivation is to play!

I took a couple videos from daycare to illustrate these points.  This first video shows Miley, the Havanese, and Luke, the Chihuahua
Terrier mix, engaging in a fair and balanced play where each dog
initiates play after a quick pause. Luke displays a behavior that is
very informative about his state of mind. He places his head and chin over Miley’s shoulders.
This is a sign of assertiveness. If the display is quick, as in the
video, there is no need for concern.  However if the display is more
forceful and prolonged, intervention is necessary!

In this second video Mitch, the beagle, has his hackles raised and Ziggy, the miniature schnauzer, tackles Mitch to the ground and chews vigorously on his neck while growling.  This can appear to be aggressive, but look at their body tension. Mitch freezes for a second and then makes a large, exaggerated movement into a play bow. This is a solicitation to play. Mitch’s hackle raising is simply a sign of excitement, the neck biting, a very gentle, benign play style and the growling, a soft communication of play. Because their play is very vigorous, it is important to require that the pups disengage for short breaks often so that levels do not escalate into frustration, similar to children when they get too aroused!

As you can see,  it can be difficult to interpret the dogs signals unless you look at the overall context.  Each element in and of themselves can have multiple meanings.  The combination of signals is what provides the full story of what the dogs are communicating.
