“No” is not a behavior
How many times a day do you say NO to your dog? How many times does the dog respond? Most of the time the response to your yelling NO at your dog is the tone in which you say it that grabs their attention, not the word itself. Dogs associate everything with one thing. Sit means put my butt on the ground, down means lie down, stay means don’t move, but NO means way too many things. NO, don’t chew on my shoes. NO, don’t eat my steak. NO, get off the counter. NO, get over here
