they do good around others at first they might bark at each other for a while to show the other dog how tougf they are. ; p theyll growl at each other, try to bite each others tail, sometimes they'll be biting each other having kind of like a dog fight; might sound scary. ; p if you feel that its going to far split then away from each other. they'll chase each other around, and other ther simple things.
Usually they play rougher with other dogs than with humans. But play usually consists on running, chasing, biting/nipping, jumping, barking, whining. Usually a dog who doesn't want to play would warn the other dog away by growling and biting or simply running away. Hope this helped.
