Mayerzon No-Pull Martingale Dog Collar, Blue, Medium, Adjustable Training Fit

The Mayerzon No Pull Dog Collar is a martingale training collar designed to help interrupt leash pulling, with links built into the collar and an adjustable medium fit for 14.5–18.5 in (36.8–47 cm) necks.

• Martingale links are integrated into the collar — training pressure comes from the collar itself.
• Blue, size M, fits necks measuring 14.5–18.5 in (36.8–47 cm) — choose by your dog’s neck measurement.
• Smooth links and soft rubber elements — apply training pressure while helping protect sensitive neck areas.
• Heavy-duty nylon and a sturdy D-ring — made for leash walking with dogs that pull.
• A gentle tug provides a pressure cue — helps communicate during walking training.

Pulling on leash can make walks difficult to manage and training cues harder to communicate. This collar is made for walking practice and correcting unwanted pulling behavior. Its martingale design applies pressure when the leash is tugged, giving the dog a cue through the collar while keeping the outside appearance similar to a regular collar.

How does the hidden martingale design work?

The links are built directly into the Mayerzon collar rather than added as a separate chain collar cover. When the leash is tugged gently, the martingale mechanism applies training pressure to help interrupt pulling and communicate a cue. The design is intended to support calmer, more manageable walks.

• The collar’s exterior has the look of a regular dog collar.
• It is intended for walking training and correcting unwanted pulling behavior.

How do I choose the right size and fit?

The medium Mayerzon collar adjusts to fit a neck measurement from 14.5 to 18.5 inches (36.8 to 47 cm). Measure your dog rather than relying on a size label alone; the collar is adjustable, and the measured fit should be snug without being tight.

• Measure just under the jaw and behind the ears.
• Position the collar high on the neck, just below the base of the skull.
• Use the neck measurement to confirm that size M is within range.

What materials and details are made for walking use?

The Mayerzon collar combines heavy-duty nylon with a D-ring for leash attachment. Smooth links and soft rubber elements provide the martingale pressure while helping protect the respiratory tract and sensitive areas of the neck. The materials and hardware are made for repeated walking use, with the collar designed to last for years.

• Blue color.
• Martingale training collar construction.
• Adjustable fit for selecting the correct neck range.

This blue medium collar suits dog owners working on leash-pulling behavior who can match their dog’s measured neck to the 14.5–18.5-inch range. Its built-in martingale links, adjustable fit, nylon body, and D-ring make it a walking collar designed for training cues rather than a separate chain collar cover.
