When left to their own devices, dogs love to engage each other in a bout of playing. To the uninitiated owner who observes the interaction, the behavior can seem cute, odd, and even worrisome if things seem to be getting too rough. The fact is, canines enjoy this type of contact with each other and rarely does the contact get out of hand. In a way, it is a social dance they perform with one another from the time they are puppies through adulthood.
