Need to shed a few pounds? Is your pooch looking a little heavy around the collar, too?

Taking your dog for a jog can be a good way for both of you to stay fit and trim. An estimated 40 percent of all dogs are overweight, which can lead to serious problems such as heart disease and arthritis. But remember that pets, just like people, have limitations depending on their stage of life, body condition and general health. For example, forcing a gangly three-month-old lab or a chubby eight-year-old bulldog to keep up with a marathon runner could lead to bone, joint and heart woes.

Hot weather is especially a concern, because dogs don’t sweat and often have trouble keeping cool, thereby predisposing them to heat stroke.

Be sure to ask your veterinarian if your dog is in running shape before you and your new jogging buddy hit the pavement.
