nowt for a dog that pal, i bet there in good health. Id would love to be able to have the spare time to walk 15 mile a day with mine, but sadly iv got graft, and so mine get a run behind a vehicle/bike to save time.
I used to be beating on the moors 6 days a week from 12 august until early december, the same dogs every day would cover 20+ miles no bother, over very rough terrain, working their socks off. And they could still do more, fit dogs are super athletes.
thats like nearly doing the west highland way every week, yous are all full of shit
