How To Make Raw Hide Bones Teaching A Dog To Play?

Teaching a dog to play? - how to make raw hide bones

We have recently adopted a 3-year-old dog from the Humane Society. It is very sweet, loves people and is completely domesticated. The only problem is that they want to play! We'd love to learn to play, because we thought that would be a good way to burn energy and have to be some excitement in his life - go for a walk instead and treat yourself and take the training.
Do you have any tips on how to do this? He loves it for real food (like raw hides chew), but not chew bones, plastic smell of food. Do not place objects in their mouths, not food - no balls or squeaky toys or string. He seems to want to play and sometimes goes to the back, legs in the air with his mouth open. The way the top, and GAMe, I know it is not intended to represent a risk because it is completely quiet (no hum) and back and wags his tail and tried to resume dialogue, if you stop playing. This kind of game that is unpleasant for me, because he does fear of being discovered huge teeth and break you, even if a contact. I want to get this kind of game of tug or transfer, but how do I do that? It is a very aggressive dog and has been tested in the Humane Society of aggression (who discovered it would be good for kids of all ages - one of the lowest possible attack). Also, I am a little worried that if we work hard to teach him how to find and chew things, they could also use this transfer to every home! Any tips?
