f**k OFF
its true mate. distance is measured by a gps watch for running, down to 100th of a mile.
But why??? A pup needs to waste its energy running, jinking, pulling things, playing, etc, etc, etc, not f*****g walking. Is this all on hard roads? Your doing untold damage IMO
some of its been on stone tracks around the wood but most of its been in the fields. he gets to play plenty with the terrier. hes getting a damn good education and experiences things that will no doubt come in handy when he is a adult dog.
