A year ago this was our 8 week old Great Dane puppy, Yeager. He was smaller than both of our cats:
And 120 lbs later:
He thinks he's a lap dog, and he's so gentle it's incredible given his size. His back is just below my belly button (I'm 5'4"). He can stand at the counter and put his head into the sink, all paws on the ground. His ball is a soccer ball, which he carries around in his mouth with ease, and he loves stealing firewood from the pile and running around the yard. A total Momma's boy, too. He stays by my side even outdoors without running off. One cat likes him; they often gaze out the window together with the cat on the window sill and Yeager resting his jaw on the back of the cat (it's a big cat). The other one could take or leave him and has often swatted him in the face for the tiniest sniff.
