I have the world's first heat seaking guided missle -a Whippet! (Actually, they say that owners will eventually look like their dogs, so I bought a whippet as I needed to lose some weight!)
Trouble is he's a sprinter -all out for 10 tosses of the aroebe disc and then he's spent.
When I started my jogging experience 10 years ago, I weighed less than I do today. I couldn't jog a continuous mile (I was even on my college track team -read 'field events'). I went from 11/12 minute miles down to 3 miles at just over 6 minutes per mile. I really really enjoyed that.
As I said I weigh more now, but am very comfortable -no aches and pains (I'm relatively young yet), I attempted to beginn jogging last year (didn't want to stick withit) and I was able to complete a continuous mile in around 10 1/2 minutes -far better when than when I was in 'shape' just after college.

How did you get your dog in shape so quickly? It's cruel and dangerous to force a dog to run that far without sufficient conditioning (unless you got a dog that already had been conditioned, and if that's the case my comments do not apply to you.) Dogs, of course, will give their all to please their master so one must be mindful not to push them too far. That goes also for the lazy dog exersizers who drag their dog behind a bicycle.
