A perfect solution for your escape artists, our Martingale Adventure Collar offers a more comfortable solution over traditional choke/pinch collars. Simply attach your leash to the D-ring and the collar will automatically tighten as your dog pulls on the leash, preventing them from being able to slip out of the collar during your walks together. All of our nylon has a vibrant sheen coating on top. Available in three adjustable sizes, each one features neoprene padding and reflective accents like all of our other adventure nylon! Be sure to check out our matching adventure leash too.
