No play of any kind in the house helps a dog stay calm. Home is where the dog rests because the dog is tired from regular and appropriate exercise they are getting outdoors. Are humans in the house allowed to put on baseball gloves and throw a ball around the living room? Unlikely. Is it OK for the kids to have a goal tender at one end of the hall stopping pucks being shot from the other end of the hall? Such play is reserved for outdoors. The same applies to the dog. Play is for outdoors. Revving up a dog to a highly excited state of mind, to what I call the “Snap Point” will result in a bite, guaranteed, 100%, its going to happen sooner or later. When a dog’s level of excitement rises, somewhere along that escalation line they will ‘snap”. In this state of mind, a dog essentially cannot be “responsible” for their actions. Before a Police dog goes after a bad guy, the dog is revved up by their handler via some form of spirited play. When the dog is sufficiently excited, the handler will redirect that excited state of mind – almost hysterical – to a new task by telling his dog: if you find the bad guy, I will give you a reward, then the dog goes to do his or her job: find the bad guy. It is not a great idea to do the same to your pet indoors. Indoors where we want dogs to be calm. Controlling the level of excitement of your dog is key to having a well mannered pup in the house.
