But now, with the help of the Park Spark Project, launched by artist Matthew Mazzotta, a dog park in Cambridge, Mass. has found an innovative (and very eco-friendly) way to recycle the waste your dog leaves behind -- an on-site methane digester. The concept is simple. People put dog poop into an air-tight container and it begins to produce methane, an odorless, colorless gas that is a major part of the natural gas many of us use in our homes. The methane is then piped into a ...

Andrea Metcalf Both you and your pooch love playing at the park, but you can use the time for more than just hanging out with your dog. The park is a great spot for strength training. It only takes a little planning. We talked to some pet people and fitness experts to get the lowdown on how to involve your best buddy in your workouts. Before You Exercise "Remember to stretch out, and that goes for your dog too," says certified professional dog trainer Sarah Westcott of the Doggie Academy in New York. "Teach your dog how to bow for a great downward-dog-type stretch. Use a treat to lure your dog's head up and back to stretch his chest, then all the way around to his rump from either side ...

Anna Westhoff This week's guest columnist is my wife Anna. There's as wide an array of doggie personalities as human personalities. The dog park taught me that.
