Well, 2 out of 3 ain't bad! In Gunnar's case, the throw and fetch thing works well. In his case, the game becomes throw-fetch-chew. The goal seems to be to shred the tennis balls or devour the Frisbee. Oh, well. Perhaps he'll eventually come to enjoy the repetition part of the game. I hear that those proverbial puppy teeth will fall out and that he'll be a lot less chewy, if there's such a word. Hmmm. Spell-check seems to think there is.
We did have an accident this afternoon, though. Gunnar violated the zone of our invisible dog fence and got the reminder that he shouldn't do so. The flags are down now so the visual cues are gone. I imagine that this will be something he remembers.
