I've been fearing it for sooo long. Garrett is definately 100% mobile and looking for trouble. This evening on the changing table he went from laying down to sitting up all on his own. Earlier today he crawled over to Aspen not once, not twice, but three times, to ask if he wanted to share his bone. Thankfully, Aspen declined very politely! Good dog, Aspen. He's squealing, squacking, crawling (commando, still) and rrying to pull up on everything. I am never going to be able to keep up!! Its fun, but scary. . . if I turn my back for a second, he is in to something new.
