The ppark w-Series dog martingale collar can be used as a regular collar (when leash is attached to both D-rings), or a training martingale dog collar (when leash is only attached to the small loop D-ring).

This is a great training aid for dogs that are easily scared or skittish and try to escape. Made with post-industrial recycled yarn, the threads are new and not previously used. In addition, because it is mostly fabric, the ppark W-Series dog martingale collar is made to minimize the loud jingling sound that come from chains on traditional martingales.
