First- I don't like hitting animals for any reason, so we use "the big scary noise" when Greta jumps up. She learned real quick, that if she jumps up, she will hear it again! The big scary noise is a sharp "bad dog" command. We only use it when they break rules that they know. Other times, when they do what we don't like, but haven't covered yet, she hear a sharp "NO". Keep your commands short, and always use exactly the same words, and she will be easier to train. Ours understand; Let the dog out? Feed the dog? Get the dog! (invitation to play) Sit, Circle, Down, Roll, Goodies?, and the one you never say in jest at my house, "Car Dog? They both go absolutely nuts running in circles, then run to the leash and halter hook on the door, and keep barking until you get there. Did I mention that they are a medium Blue Heeler, and a huge malamute/shephard? It's deafening! They also know that if a dish is on the floor, they can't touch it if it has silverware on it. Good luck to you. It will all be very rewarding when you are done!
