Turns out the Energizer Bunny ain't got nothing on Bo. Our weekend was spent watching him run the length of a soccer field again, and again, and again and...you get the picture. This boy can fetch. And jump. I think I'm going to teach him to jump through my arms or something geeky like that. The great thing is that all the exercise means he's dog-tired and ready to do nothing but laze about when he actually comes inside.
