Metal buckles, car strap, and adjustable fit. Only tried on my dog and did not fit. 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.
