I put the dog in a sit, put a treat in my hand, make a closed fist. The dog will smell it, paw it, etc and I tell them to wait..as soon as they back off of the hand I open up my fist and tell them to take it, repeat as necessary, it only takes a few times and they get it. I have trained all three of my dogs this way with great results.
