Fei and Eve Hand-Braided Martingale Dog Collar for Medium and Large Dogs

Fei & Eve’s hand-braided martingale dog collar is made for medium and large dogs, with a soft SP cotton rope and a 210D nylon tightening loop.

• Martingale leash loop — tightens gently when the leash is pulled and relaxes when it goes slack.
• Three fixed neck sizes — measure your dog to choose the right fit.
• SP cotton rope — synthetic polyester yarn with a soft, cotton-like feel.
• Hand-braided construction with a 210D nylon loop — combines a distinctive braided look with a loop designed to hold its shape.
• Slip-on style — goes over your dog’s head without a buckle or slider.

For walks with a medium or large dog, a martingale collar offers a leash-connected loop that responds to tension rather than relying on a conventional buckle closure. Fei & Eve’s design is intended for dogs whose neck measurements match one of its fixed sizes. Measure before choosing, since the collar does not adjust after purchase.

How does the martingale collar tighten?

The leash attaches to the nylon loop, which gently draws the rope loop tighter when the leash is pulled and loosens again as soon as the leash goes slack. The collar slips over the head, so putting it on does not involve fastening a buckle.

• Attach the leash to the nylon loop.
• The rope loop responds to leash tension and releases when tension eases.

How do I choose the right neck size?

Measure around the middle of your dog’s neck with a soft tape, then select the size whose range matches that measurement. The sizes are S for 14–16.5 in (35.6–41.9 cm), M for 16.5–19 in (41.9–48.3 cm), and L for 19–23 in (48.3–58.4 cm).

• Choose by neck measurement rather than breed.
• Good to know: sizes begin at 14 in (35.6 cm), and the collar is not adjustable.

What is the collar made from?

The rope is braided from SP cotton, a synthetic polyester yarn with a cotton-like feel. Each collar is finished by hand and paired with a 210D nylon loop; the braided construction is designed to hold its shape over time.

• The yarn is polyester, not natural cotton.
• The rope is described as gentle on the dog’s neck and made to stay strong through repeated walks.

Which dogs is this collar designed for?

This fixed-size collar is intended for medium and large dogs whose necks fit the S, M, or L measurement range. It is not suitable for small dogs under 20 lb (9.1 kg), and it has no buckle or slider for changing the fit.

• Measure the neck before selecting a size.
• Choose only when the measured neck falls within one of the three size ranges.

Fei & Eve’s hand-braided martingale collar suits medium and large dogs with a matching neck measurement and people who want a slip-on leash collar with a tension-responsive loop. Its fixed sizing makes an accurate neck measurement central to choosing the right fit.
