OK, let's see. Tani LOVES to chase lizards. I'm in Florida, so there are little chameleons everywhere - they scatter wherever you walk. She will spend as much time as I let her stalking and chasing them. As far as I know, though, her efforts have gone unrewarded!
Koji, the new BP, I have nicknamed "the Ant Bully" because he totally stalks poor little tiny ants. He ends up stomping his big puppy paw on them, then licking them up. Eeeew. Niko, the old greyhound, doesn't do the toy thing so much. He likes to do one lap around the yard, then pick out a spot in the sun, lay down, then roll on his back and stretch. It's the only time he looks youthful again!
