More: Karl is a hoot! While he loves to wrestle and play catch, he seems to think he’s the size of a chihuahua and will invite himself onto your lap to prove his theory. His eyes always easily express his dog thoughts and his dog feelings. He’s brave and can be loud at times but inside he’s a squishy soft hearted teddy bear. Karl loves children of all ages and will always go out of his way to give them a polite hello. He is always ready to learn another trick in no time and is a prime example of how fast GSDs can learn. He can already sit, stay, lay down, shake, sit up (fancy boy), spin (both ways) and roll over. He also just learned how to bark and also whisper on command. We sure do love our giant grizzly bear.
