Product Description
The CollarDirect Chain Martingale Collar in Medium earns its own place because sizing matters enormously with martingales — a large martingale on a medium dog simply doesn’t function correctly. This is the same premium build as the Large, scaled for mid-size breeds.
You get the identical genuine stainless steel chain loop that won’t rust or stretch, the same reflective-threaded nylon webbing for night visibility, and the same lockable quick-release buckle for easy on and off. The difference is purely dimensional: this one fits Border Collies, Australian Shepherds, smaller Labradors, Whippets, and similar mid-size dogs.
My rule for martingales: buy the size where your dog’s neck measurement falls squarely in the middle of the range. A martingale at either extreme of its adjustment can’t deliver the limited-slip action properly — too loose and it slips off, too tight and it never releases.
The medium hits the sweet spot for the most popular dog sizes, combining escape-proof security with all-day comfort. The reflective threading is a genuine safety upgrade for evening walks.
If your dog is a mid-size breed or a smaller narrow-headed escape artist, this is your size. Get the fit right and enjoy worry-free walks — order today.
Mid-size dogs are the most common escape artists at the park — big enough to pull hard, quick enough to bolt. This medium sizing addresses exactly that group with the full premium feature set. The reflective threading is particularly valuable for the evening walks that fit busy schedules.
Frequently Asked Questions
What's the difference between the Medium and Large CollarDirect chain martingale?
It's purely sizing — same chain, same limited-slip design, same hardware quality. Medium suits mid-size breeds (roughly 25–60 lb dogs, depending on neck), while Large fits big breeds. Measure the widest part of the head and the neck; pick the size whose adjustment range covers both measurements.
How do I fit a chain martingale so it works correctly?
With the collar on and the chain pulled tight, the two rings where the chain meets the nylon should come close but not touch — about a finger's width apart. If the rings touch, the collar is too loose and won't correct; if they can't come together, it's too tight and will choke.
Is a chain martingale humane for training?
Used correctly — fitted right, with quick pop-and-release leash technique rather than sustained pulling — a chain martingale is a widely accepted training tool recommended by many professional trainers. It should never be yanked hard or used as a constant-pressure device.
Will the metal chain rust if it gets wet?
The chain is chrome-plated steel, which resists rust well for normal rain and walk use. After swimming or heavy mud, rinse and dry it to prevent corrosion at the weld points. If you need a fully rust-proof option for water dogs, look at stainless-steel chain martingales.
Can puppies wear a chain martingale collar?
It's better to start puppies on a flat buckle collar or nylon martingale. Chain martingales are training tools for adolescent and adult dogs whose neck size is stable — a growing puppy would need constant refitting, and the chain correction is unnecessary for basic puppy training.
