Tim (first page) is undefeated so far as a sled dog. He can pull 250 lbs by himself for hours, and handles the combined run volume of Mr & Mrs lakercr without effort.
Funny! There is no debate about who would do the distance, but I am not sure even he could “catch” one. Dogs wear out very quickly when they sprint and overheat in the open range. They also don’t turn as sharp or quickly. Besides don’t you feed him well. or do you make him catch his own food?
