What size prong collar for my dog?

Dogs can bring immense joy to our lives, but proper training is essential to keeping them happy and well-behaved. As a responsible dog owner, selecting the right prong collar size is important for effective and humane training sessions. This comprehensive guide will help you understand prong collars, how to measure your dog, and tips for what size prong collar for your dog

What is a Prong Collar?

A prong collar, also called a pinch collar, is a training tool made of interlocking metal links that places pressure on a dog’s neck when pulled. It is commonly used as an alternative to choke chains that restrict airflow and can cause harm if not fitted properly. Unlike choke chains that tighten under pressure, prong collars distribute correction evenly around the neck.

When fitted correctly, prong collars allow trainers to communicate with dogs through tactile guidance rather than restrictive pressure on the windpipe. They are designed to gently catch and release the dog’s skin and fur to deliver clear correction signals during obedience lessons. With proper sizing and humane usage under a trainer’s guidance, prong collars can be an effective part of positive reinforcement techniques when used sparingly and judiciously.

Prong Collar Size for dog Guide

Selecting the appropriate prong collar size for your dog is critical for ensuring an effective yet humane training experience. Most manufacturers provide detailed sizing charts to help you determine the best collar for your pup’s measurements. Let’s review the key factors to consider:


The thickness of the metal links that makes up the collar. Thicker gauges are recommended for large, powerful breeds while thinner gauges work well for gentle giants and smaller dogs.


Flat-sided versus round-link collars. Flat-sided have a more shallow profile while round links tend to be stouter. Consider your dog’s neck shape and fur thickness.

Dead Ring Diameter

The circumference of the inner prong collar ring that sits flush against your dog’s neck. Measure this accurately for a custom fit.

Dog Breed & Weight

Certain breeds have wider or thicker necks naturally. Heavier dogs also require thicker collars for durability and control during training.

Fur Thickness

Long coats need room to move freely underneath without restricting the dog’s range of motion. Ensure links are spaced enough for fur to flow through.

Well-respected manufacturers like Herm Sprenger have precise sizing charts to guide you. Taking accurate neck measurements with a measuring tape is key to selecting the right dead ring diameter and avoiding a collar that is either too loose or restrictive.

How to Fit a Prong Collar

With the proper size collar in hand, follow these steps to fit your prong collar correctly:

Measure Neck Circumference

Use a fabric measuring tape snugly around your dog’s neck, just behind the ears. Record this number to compare to sizing charts.

Check width with two fingers

The collar should allow you to comfortably fit two fingers under it around the neck. It should sit high on the neck close to the ears.

Fasten Collar and Check Range of Motion

Click the collar together and ensure your dog has full range of motion turning their head from side to side without restriction. The prongs should sit evenly spaced all around.

Check for Slippage & Adjust as Needed

With gentle lead pressure, the collar should not spin or slip sideways. Adjust the tightness using the side buckles if needed until it feels sufficiently snug while still allowing one finger underneath.

Proper fit is critical for the collar to work as intended without causing unnecessary pressure or irritation. Take your time getting the measurements right from the beginning.

FAQ about Prong Collar Size for dog

Do prong collars hurt dogs?

When fitted and used properly by a competent trainer, prong collars do not harm dogs but instead use tactile communication to gently reinforce commands. However, they must never be left on unattended or used to restrict a dog’s natural movements.

How tight should a prong collar be?

It should fit snugly with about 1-2 fingers able to slide underneath. Tight enough so the collar does not slip but loose enough to prevent pressure or indentations on the dog’s skin.

Which way should the prongs face on the collar?

The closed ends of each prong link should face outward away from your dog’s neck for maximum contact with the fur and skin, and closed ends inward may pinch.

When should I use a prong collar during training?

Only during controlled sessions with a professional trainer until your dog has learned basic obedience. Prong collars require experienced handling and should not be a dog’s primary collar for casual use.

Will prong collars damage my dog’s fur or skin?

No, as long as the correct size is used properly during training sessions under a trainer’s guidance. Prong collars are designed not to catch or pull out fur when fitted and used correctly for training purposes only.
