My Shitzu comes running WHENEVER he smells me lighting up. He loves it, gets right in my face. Usually he lets me blow him 2 good hits then he takes off to play with the cats. He is funny as hell. I have told this story to my friends and no one believed me till they saw it for themselves.
I must admit, the first time I got him high, he wasn't looking for it, now he is an old stoner
It is either he associates me smoking with hang with dad time, or, he likes it. Personally, the way he behaves and the fact that he can hang with me anytime makes me believe he likes it.
