Sit is very easy for Hachi. It's what he does naturally when he's waiting or is curious. Hachi almost never lies down while we interact with him. That makes it hard to teach him how to lie down when we say "down".
Then, I was playing with him, and I slapped a toy onto the ground in front of him. He dove into a down to try to capture the toy. A light bulb went off in my head... it was a way to get him to lie down!
That's where we are now. I say "down" and then I slap the ground in front of him to lure him into a down. I am gradually increasing the time between saying "down" and slapping the ground because I want him to eventually respond to the word rather than responding to me slapping the ground.
Please realize that there is nothing aggressive or intimidating about me slapping the ground. It's completely derived from play and he responds like he did when I had a toy in my hand.
I mix in lots of play with "training" - it's my hope that training will feel as fun as play to him. You'll see a section in the video of me playing tug with him in the midst of training.
I hope that you enjoy the video of Hachi in action!!!
