This is the best tutorial EVER on this topic. Short, easy to implement training taught by Kikopup on how to stop unwanted behavior with an interrupter. Anyone can teach this, even if you have never trained a dog. Since the topic of "how to stop my dog from ____________" comes up so often here on the forum, I would love to see this made into a sticky.

If everyone did this simple training with every new dog and new puppy, then consistently used the positive interrupter instead of yelling, or doing something worse than yelling, so many problems would be solved. I love the way Kikopup (Emily) explains WHY this training is so important and why it works!

Also, watch the video several times and pay close attention to Emily's comments on the reasons why a negative response to behaviors you don't want your dog to do is, at minimum, a waste of time because it does not tell the dog what you want him to do. If you consistently use negative interrupters, such as yelling "NO!", you actually reinforce the behavior you don't want and, worse, damage the relationship you have with your puppy or dog.
