And, make your training sessions no more than five, MAYBE ten minutes. The session should never get boring to your dog. Always stop while they are really into it. I recommend training with a clicker. And, again, find out what your dog really likes. If he likes food, give him food. If he likes praise more, stick with that. A toy, whatever. It has to be custom fit for your dog. But, I think one of the biggest things is making the sessions short. It's better to do ten five minute sessions a day than one or two long, stressful sessions. Good luck!
