Canine Cardio

The DogTread Treadmill is a modification of the familiar exercise machine in homes and health clubs, with special features for dog safety — a helpful invention in a nation in which over half of all pet dogs are too fat. A somewhat higher percentage of cats is overweight, but it’s unlikely selling a cat treadmill has been considered. The Association for Pet Obesity Prevention points out that pets can develop Type 2 diabetes, high blood pressure and osteoarthritis — the problem stems from insufficient exercise and overindulgent owners. The DogTread Treadmills run $499-$899.
