Giving of your time is hard; so is finding enough time to work out. The Colorado Humane Society has the perfect solution: Walk a dog. Or two, or three. With no training, a volunteer family, classroom or scout troop can pop by the CHS any time and take a frisky Fido out for a frolic. Everyone wins: The dogs calm down -- and perhaps get adopted -- and their walkers get exercise, too. The shelter logged just shy of 1,000 dog walks between April and December last year. These dogs are made for walking.
