I do A LOT of dog like stuff. I'll growl, tilt my head, whimper, go on all fours..... Even when I yawn, I have these weird way of stretching Ny tongue out the way a dog does. I tend to do all of it without really noticing it, too. When I was little (ages 3-6-ish) I even used to kind of 'roleplay' as a dog around the house. I don't know why, I guess I was always a furry at heart.
