Nylons stuffed with cat food are used by Judy Harris to mark the pavement with scent. This helps guide the dogs over paved surfaces as they practice tracking in Cosmopolitan Park on Tuesday. Besides training her dogs in tracking, Harris is also an agility instructor at the Columbia Canine Sports Center. Both of her standard Poodles, Desi and Moni, are also therapy dogs through Therapy Dogs International.
