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 their head and clip a couple buckles, and you’re ready. And when you're done with your adventure, one press has them 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.
