bix LOVES to be chased.  loves loves loves it.  i don't know why that is, what in a dog's instincts would cause him to want to be the prey rather than the predator, but whatever it is, he's got it.  this is him going slow - he can really pick up the pace when he wants to - and it's all fun and games until jelly nips his tail at the very end.  silly dog.
