Dog Collar Size Guide: How to Measure Your Dog Correctly

Choosing the right dog collar size is essential for your dog's comfort and safety. A collar that is too tight can cause discomfort, while a collar that is too loose may slip off during walks.

In this dog collar size guide, we explain how to measure your dog's neck correctly and how to find the perfect collar size.

Why the Right Dog Collar Size Matters

A well-fitted dog collar should be secure without restricting movement or breathing. The right size helps prevent irritation, ensures comfort during daily walks, and keeps your dog safe.

Many dog owners choose a collar based on breed alone, but every dog is different. Measuring your dog's neck is always the most reliable way to find the correct fit.

How to Measure Your Dog's Neck

Measuring your dog for a collar only takes a few minutes.

Use a soft measuring tape and wrap it around the base of your dog's neck, where the collar would naturally sit.

The measuring tape should be snug but not tight.

A good rule is the two finger rule. You should be able to comfortably fit two fingers between the collar and your dog's neck.

If you do not have a measuring tape, use a piece of string and measure it afterwards with a ruler.

How Tight Should a Dog Collar Be?

One of the most common questions dog owners ask is: how tight should a dog collar be?

A properly fitted collar should not slide over your dog's head, but it should also not leave marks on the skin.

You should always be able to fit two fingers between the collar and your dog's neck. This ensures comfort while keeping the collar secure.

Dog Collar Size Chart

Every brand uses different measurements, so always compare your dog's neck size with the size chart provided by the manufacturer.

At Cano Ateliers, our collars are available in the following sizes:

Small: 25.4 cm to 32.6 cm

Medium: 31.8 cm to 38.8 cm

Large: 36.2 cm to 43.3 cm

If your dog falls between two sizes, we generally recommend choosing the larger size for additional comfort and adjustability.

Common Mistakes When Measuring a Dog for a Collar

Many dog owners accidentally measure too loosely or use an old collar as a reference without checking the actual neck size.

Always measure your dog's neck directly and avoid guessing based on breed, weight, or age.

Another common mistake is measuring too high on the neck. The collar should sit comfortably around the lower part of the neck where it will normally be worn.

Finding the Perfect Collar

A quality leather dog collar should feel comfortable, secure, and durable enough for everyday use.

Taking a few minutes to measure your dog correctly helps ensure the best possible fit and allows your dog to enjoy every walk in comfort.
