Obedience School + 2

I spent a little time with Duke yesterday trying to reinforce "wait" Some sucess. Today I was trying to reinforce "Return" (Come!). I might as well have been talking to the wall. Did he once pay attention? Hell, no! All he wanted to do was see how far he could get on the 100' of rope. We went to the dog park where he decided to go after a dog not in the park and I had to go after him. He must think I'm made of money to buy him obedience sessions.
