Oh, a tired dog is a good dog. I take along a supply of tennis balls and the flinger thing, take my dog to a spot where he can go off leash, and run him until his heart bursts...
He works off steam and is ready to be a calm, nice leash dog.
Retrievers are easy to work this way.
Tennis balls will work like a leash too. All his attention is on that green, slobbery ball.
