dancing dogs indeed

I was recently at a show where dancing dogs were one of the displays.  The dogs were having fun, freestyle with their human guardians.  Some of the people explained to me that this was less restrictive than mainstream competition and from where I stood it did appear that 2 and 4 legged were all having good times.  Unlike the story in the paper I have recently seen where the dog guardian claims that his dog likes to walk on 2 legs only for great lengths of time.  On closer inspection of this picture it would appear that the dog has a rope around its front legs- to pull and hold it up.  Wasn't so happy to see this and cant imagine why any dog would prefer to walk this way.
