Mayerzon Martingale No-Pull Dog Collar, Black M/L, Reflective for Training

The Mayerzon Martingale No-Pull Dog Collar is a walking and training collar designed to help discourage pulling, with a 17.75–21 in (45.1–53.3 cm) neck fit and reflective webbing.

• 17.75–21 in (45.1–53.3 cm) neck range — choose the M/L size to suit your dog’s measured neck.
• Gently tightens when your dog pulls and loosens when relaxed — supports calm leash walking.
• High-visibility reflective webbing — helps keep your dog visible on low-light walks.
• Soft neoprene padding and a heavy-duty D-ring — features for walking and training use.
• Slider adjustment and quick-release buckle — make fitting and taking off the collar straightforward.

For dogs that pull, lunge, or chase on walks, this martingale collar provides a training-focused alternative to an ordinary fixed collar. Its tightening-and-release action responds to leash tension, while its understated collar appearance suits public walks as well as training sessions. The black version is made for everyday outdoor use.

How does the Mayerzon collar help with pulling?

The Mayerzon Martingale No-Pull Dog Collar gently tightens when a dog pulls and loosens when the dog relaxes. Built-in two-way chain links apply gentle pressure as the collar tightens, helping teach a dog to walk calmly beside you rather than pull, lunge, or chase. The design looks like a regular dog collar, so it has a discreet appearance during walks.

• Made for leash walking and training.
• Pressure changes with pulling and relaxation.
• Available in black, Army Green, and Khaki.

How do I choose the right size and fit?

The M/L collar fits a 17.75–21 in (45.1–53.3 cm) neck. Measure your dog before choosing this size, then position the collar high on the neck, just below the base of the skull. If it slides down despite a correct fit, that is normal; a wider backup collar or a shorter leash can help keep it in place.

• Adjust the fit with the slider buckle; removing or manually adjusting links is not required.
• The size range is the neck measurement to compare with your dog’s neck.

What features make it practical for daily walks?

The Mayerzon collar combines reflective webbing with soft neoprene padding, a heavy-duty D-ring, and a quick-release buckle. The reflective material is intended to improve visibility on low-light walks. An instruction manual is included; read it before use.

• Suitable for training or everyday walks.

This black M/L collar suits dog owners working on calmer leash walks, including those walking in low light or using the collar for everyday training. Its fit is intended for necks measuring 17.75–21 in (45.1–53.3 cm), with placement high below the base of the skull.
