Thanks for the site! We actually have been touching him at odd times since we got him at 8 1/2 weeks. We touch him when he is sleeping, wake him up as well, we touch him when he eats, plays, chews on toys, goes pee and poo (lol I am sure I look odd when out on a walk doing it) we use touch as a very positive praise for him.
We tried to use the flashlight idea with the little red beamy light, yea that is now a "OMG THING TO CHASE!" same with a regular flashlight. I do flash the porch light on and off when its time to come in and I think he is starting to get it.
I have a hand signal for sit, down, and even eat and potty but could use more ideas, will check out the website! Thanks again!
