Nick, the youngest of the Jonas Brothers, just received the cutest birthday present ever -- a puppy he named Elvis. He was spotted out and about walking his new best friend. Nick works hard to keep his diabetes in control, so I'm sure the future walks and runs with his dog will be a welcome addition to his exercise routine.

Do you have a dog? Dogs can be a great motivator for exercise. Even if you've had a long day at work and the last thing you want to do is exercise, it's hard to say no to those pleading puppy dog eyes. In fact, statistics show that dog owners cover more ground than your typical gym-goer.

If you're thinking of getting a dog, be sure to choose a breed that suits your lifestyle. Most breeds (including my lazy English Bulldog) are thrilled to go for a stroll around the neighborhood. But if you're looking for a dog who will willingly join you for a run or bike ride, be sure to choose a longer-legged, energetic breed.
