Our Martingale Chain Dog Collar is a heavy duty, reflective, locking, nylon clasp chain martingale dog collar.  It has many features not normally found in martingales.

The collar is 2mm thick and very strong and made for the largest of dogs.  Its quality nylon webbing contains reflective stitching for improved nighttime visibility.  We use a 304 grade welded link stainless steel chain which we verify through independent lab testing. (Link to lab test)

We also feature a lockable nylon clasp which prevents an accidental releasing of the latch when grabbing the collar.

Great martingale collars!

I’ve been using these collars for years. Very safe and I love that it has a lock! My favorite martingale collar. I train dogs and people… and teach the people how to use it to help perfect loose leash walking.

Great collar

The first collar I ordered was too big so I asked to exchange. Instead, they sent me the right collar and requested that I just donate the larger one to a shelter. AMAZING!

Great quality and great service

It’s great quality and great customer service. My only complaint is that they run bigger than what we measured, and wish we returned it for a smaller size
