Harnesses give smaller dogs a sense of security as they walk, skitter, and prance along sidewalks and through leafy parks. With "good DOG printed on a sea of stripes, this jaunty harness takes it up a notch (as one ubiquitous celebrity chef might say). Small size (1/2" cotton webbing with ribbon overlay) adjusts to fit pooches between 12" and 17" in girth; Large (3/4" cotton webbing with ribbon overlay) is most fitting for those measuring between 17" and 23" (approximately 13 to 20 lbs.).
