Answer 1

Dogs and wolves can run around a hundred miles in a day and do it every day for weeks, in cold climates. In 95degrees and sunny, I can outrun a sled dog for 5 miles, to the point they’ll lay down and quit. Sweating is a huge advantage in warm climates for running distances, which was our primary hunting method.
