Petsafe Premier Small Easy Walk Dog Harness, designed for dogs with a 15-20" girth, gently discourages pulling while walking on a leash without causing coughing, gagging, or choking. The chest strap rests low across the breastbone for maximum comfort, and the quick snap buckles on both the shoulder and belly straps make it easy to get the harness on and off. Soft, but strong nylon and four adjustment points provide a reliable fit. The belly strap is an attractive complimentary color, making it easy to identify which goes over the belly.
