Series 3 (THREE) Fi compatible martingale collar / custom colors
*** Please note: this collar requires a SERIES 3 Fi device, sold separately at tryfi.com. This listing is for the collar band only, and it is only functional with the Fi unit attached. We do still have Series 2 compatible collars here. ***
Our classic martingale collar has been reinvented as a Fi collar band! It uses the same nylon webbing and brass hardware as our classic collars, with the addition of genuine Fi endlinks.
Martingale collars have a loop of webbing where the leash attaches, which causes the collar to tighten gently when the leash is pulled. It should fit loosely on the neck, providing more comfort for your dog and more control for you.
This safer alternative also prevents your pup from backing out of their collar during walks, and avoids too much pressure on the trachea that can be caused by regular collars. Perfect for dogs who pull on leash, flight risk dogs, and dogs with wide necks.
