Proper sizing of collars is crucial for the safety and comfort of the dogs wearing them. However, it can be a confusing process for owners. By helping customers measure their dog correctly and identifying the correlating product size, you can prevent headaches and returns!

Collars should sit higher on a dog’s neck. Be sure to measure here when determining size.

A collar should allow for two fingers to slide between the collar and the dog’s neck.

Specialty Collars to Know:

Customers look to you for advice on solving a whole host of problems from dogs who slip collars like Houdini to ones that just can’t seem to get their training down.

Coastal’s solutions line offers collars specifically tailored to handling those challenges. Familiarize yourself with these unique styles of collars to become a valuable resource for frustrated customers.


1. Martingale

A martingale is a "loop" that can be formed from chain, webbing or rope that provides a limited (choke) closure on a collar.

Martingale dog collars are also known as greyhound, whippet or humane choke collars. The martingale dog collar was designed for sighthounds because their necks are larger than their heads and they can often slip out of buckle collars.

The larger loop is slipped onto the dog's neck and a lead is then clipped to the smaller loop. When the dog tries to pull, the tension on the lead pulls the small loop taut, thus preventing escape.

The collar will be comfortably loose whenever the dog is not pulling against the leash.

2. Head Halters

The halter-style collar controls the dog's head but does not restrict its ability to pant, drink, or grasp objects. Head halters, also called headcollars, are similar in design to a halter for a horse. Brand names are also used when referring to these collars most commonly Halti or Gentle Leader.

The theory behind the utility of head halters is that if you have control of the head, you have control of the body.

This device fastens around the back of the neck and over the top of the muzzle, giving more control over a dog's direction and the intensity of pulling on a leash than most collars that fit strictly around the neck.

  • Pressure on nose and not windpipe (where a collar sits)
  • Pulls the dog’s muzzle and consequently their head towards the handler.
  • Allows the owner to safely direct a strong dog away from danger.

3. Choke Chains

Also called choke collars, slip chains, check collars, or training collars, choke chains are a length of chain with rings at either end such that the collar can be formed into a loop that slips over the dogs head and rests around the top of the dog's neck, just behind the ears.

The "sound" a chain makes is very important when training a dog.  The dog hears the "jingle" of the chain, feels the correction and subsequently reacts to it.  This is part of the training process and the mystique associated with chain products.

When the leash is attached to the "dead" ring, the collar does not constrict on the dog's neck. When the leash is attached to the "live" ring, the chain slips (adjusts) tighter when pulled and slips looser when tension is released.

Training with this leash involves a quick jerk with an immediate release, called a "leash pop", "snap", or “correction".

Mind your P’s and Q’s. To properly use a chain collar create a P, with the live ring hanging through the left side of the dead ring. If it hangs to the right (like a Q) the chain encounters more resistance and won’t snap as quickly.

4. Prong Collars

Also called pinch collars, prong collars are a series of metal links that fit together by connecting through blunt prongs that point inward toward the dog's neck.

The martingale chain loop provides limited closure and allows the prongs to safely distribute the "pinching action" around the dog's neck and not damage the trachea.

The collar is designed to prevent the dog from pulling by applying pressure completely around the dog's neck.

Unlike flat, martingale, or choke collars the prong protects the trachea as it distributes pressure evenly.
