CollarDirect 213 Martingale Dog Collar, Reflective Red Nylon, 12–15-Inch Neck

Getting the most from it

For a small dog with a 12–15-inch neck, this red martingale collar combines a reflective detail with a stainless steel chain for walks and training.

Its 5/8-inch-wide nylon strap has reflective thread woven in, making the collar easy to spot in low-light settings. The martingale design uses a chain section that tightens gently when tension is applied, offering a different approach from a fixed-style collar.

To choose the fit, measure your dog’s neck where the collar will rest. Also measure around the widest part of the head, including the ears, so the collar can pass over it comfortably. The listed small size is for a 12–15-inch neck.

Pros

The soft, thick nylon strap provides the main contact around the neck, while the chain and O-rings form the martingale section. A lockable plastic side-release buckle makes the collar removable, and reflective thread adds visibility to its red design. Together, these details suit everyday walks as well as training sessions where a martingale style is preferred.

Buyer feedback often praises the collar’s control during walks and its help with pulling behavior. Opinions vary on how easily the buckle releases and how long the collar lasts, so accurate sizing and a secure fit are important parts of using it well.

What to know

This is a dog martingale collar in red, made with nylon, reflective thread, a stainless steel chain, and metal O-rings. The side-release buckle is plastic and has a locking feature. Its small size is specified for a 12–15-inch neck, with a 5/8-inch width. Measure before choosing, since the fit needs to account for both the neck and the dog’s head when putting the collar on.

The martingale format is designed to tighten gently under tension rather than remain fixed like a standard flat collar. That makes it a practical choice for owners looking for a training-oriented design that can also be used for daily walks. Keep the chain positioned as intended and check the fit after putting the collar on.

What to clarify

What neck size does the small collar fit? The small size is for a 12–15-inch neck and is 5/8 inch wide. Measure at the point where the collar will sit, and measure around the widest part of the head, including the ears, to account for putting it on.

What materials and hardware does it use? The collar is made from nylon with reflective thread. It has a stainless steel chain and O-rings, plus a lockable plastic side-release buckle.

How does the martingale design work? The chain section tightens gently when tension is applied. It is intended for training and everyday use, giving owners an alternative to a fixed-style collar.
