I took Jack, our 100+ pound black lab whose not really fat just a large mutant, for a quick trip around the river. 2.38 miles. I left my car as the time turned to 5:02 and returned in time to see it turn to 5:27. Not bad for getting tripped 3 or 4 times and dragging him away from the geese, plus he stopped to do his duty.
Last fall I couldn’t make it around the loop without stopping a couple of times.
