What I do is first teach the basics and have that trained...I have a key word...Mine is "OFF"...Being you train Dogs your one step closer than most people...I trained all mine with a Volley Ball and to not use their mouths...Only feet...Long lead and lots of praise when puppy does something correct..As they get older I set them up for failure and then we work on that area...Pups love to learn but have short attention spans...Once it gets boring I always end on a good note ...
