I have a beagle and he doesn't get as much exercise as a beagle should.. He gets to go on his runner and occasionally when we go to my grandparents he gets to run free because its fenced in.. I worry about exercising him too much because even at 7 we are struggling to keep him at 26 pounds.. He just burns calories so easily even when we give him treats and extra food.. But anyways I think that about a mile or two is good.. He'll be able to lose some weight and get healthier
