Now that the weather’s getting nicer, a lot of us are itching to get out and exercise—and, while we’re at it, give man’s best friend some exercise. Great idea, except for those of you who attach your beloved dog to your bike. This is a terrible idea. First, dogs are not built to run long distances. They’re built for short runs. Since you’re confident you’re helping them, you may not even consider you’re being cruel to your pet. Consider it from your dog’s point of view! He can’t tell you that you’re exhausting him as you drag him along. How would YOU like being forced to run alongside a bike? Second, think how vulnerable your dog is: His leash or his paw could get tangled up in your bike’s spokes! He could get startled and dart in front of a passing car, or in front of your bike. I know you love your dogs, but just get off your bikes and walk or run. Your dog will love you for getting better quality time—and he may live a better, longer life.—Anonymous
