Who, me, crazy? I thought people who didn't talk to their dogs (and cats and whatever) were nuts!
They do talk back, too, don't they? Both of mine tend to give a running commentary when they'd really rather be doing something other than what I want. Shiva's taught us hand signals, too. You get pretty quick at figuring out what she wants you to do when that big saucer sized paw is coming at you.
