I heard about a  Labrador retriever running in blind foaming  panic  with a dog house leashed to his collar, clattering  after him, down a highway. . The doghouse chased the frightened dog  for miles. It chased him out of sight. I don't know what happened to the dog. I hope  he eventually stopped,and some kind person freed him from his terrifying burden.

Me , I  finally undid my own leash , and the funniest thing....
There was no doghouse hooked to me at all . I'd lost it miles ago.
 Its in a pile, broken and splintered. Its been back there all the while.
