Callie has figured out fetch. I'm a little biased, but I think she's one of the smartest dogs I've seen. She's 12 weeks old, knows sit, down, stay, high-five, swimming, and now fetch. I'm learning a lot. Build a foundation and then put it all together. She's a pretty mellow puppy when we're home. I love this part the best...when we get done playing and walking, she lays at my feet under my desk while I write. It's like a story book. When I'm done writing we head out for another round. She keeps me balanced because she's so naturally balanced. And she's growing like crazy, so constant work is important because I don't want an out of hand dog, and so far so good.
