Kurgo - Smart Harness Black XS

The Tru Fit Smart Harness with quick-release buckles is designed to do one thing: get on fast, so you and your dog can get going. Just slip it over his head and clip a couple buckles, and you’re ready. And when you're done with your adventure, one press has him out just as quickly. A generously padded chest piece reduces stress on the trachea and sternum and disperses kinetic energy. Five adjustment points mean you can find a near-custom fit for just about any dog. Includes a 10-inch seat belt loop to prevent distracted driving, but it is not crash-tested.
X-Small harness fits dogs with a neck girth of 9 - 13 in (23 - 33 cm) and chest girth of 12 - 18 in (30 - 44 cm), weighing 5 - 10 lbs (2 - 5 kg).
