Contact your veterinarian. In the spring it seems like everyone is out jogging or speed walking, getting in shape for summer. A Kansas State University veterinarian suggests people should take a good look at Spot or Chopper and see if their dog would benefit from regular exercise. The number one reason dogs should exercise is to maintain their weight.
Exercise improves muscle tone, so it's good for show dogs.
It also builds endurance and can help prevent cardiovascular disease. And exercise can keep a dog happy. Generally, long-legged dogs or members of the sporting, hounds or working groups are best suited for regular jogging or speed walking, Erickson said. But all dogs can use regular walks. Dogs who weigh 45 to 95 pounds can go when they're more than 1 year and giant breeds who weigh more than 100 pounds can start a regular program when they're more than 18 months.
