Taking a long walk or jog with an active dog is a great wintertime activity. In the Summer, pets can run the risk of overheating or burning paw pads on hot pavement but, 'tis the season to get fit outside in the brisk chill. This weekend marks the 20th Annual Jingle Jog in Atlanta with races for running and walking . . . with pooches! As a festive touch, everyone who enters gets jingle bells for their shoes (or pup's collar). The event also includes a Best Dressed Holiday pet contest with gift certificates to Petco up for grabs for those decked-out dogs. Bring your pooch and a toy to donate to needy children this Christmas season — the fun run starts at 8 a.m. on Dec. 15.
