Keep things really positive for the dog. As the others have mentioned, find what works best for the dog. For Kai, food worked okay until he decided he was better off doing something else. He could care less about toys. Kaedyn's the same way. I do use corrections but I find myself rarely correcting them anymore and I keep things really positive especially after correcting them. You can still tell they're having a good time cause they're wagging their tails and doing things so enthusiastically. Anywho, find what works best for your dog. And clicker training is something to look into. It works so well for so many dogs.
