To get the best result out of a long distance sledge dog, dry feed is probably not the best to give it at the lunch break. The reason for this is that the amount of energy in dry feed cannot compete with the amount of energy in fat rich wet feed
Hunting dogs and sports dogs are long distance runners who expend large amounts of energy in hours of running each day, and often for several days in a row. A survey has been conducted at IHA to examine how much energy dogs expend under varying running conditions. The dogs used in the experiments are bird dogs, and the energy consumption is measured during practical winter hunting, running alongside a bike using a Springer, and on a treadmill.
