How to Measure a Dog for a Coat & Find The Perfect Fit

When the colder months arrive, a well-fitted dog coat can make all the difference to your dog's comfort. Whether you have a tiny Chihuahua, an energetic Cockapoo, or a large Labrador, choosing the right coat starts with one important step: measuring your dog correctly.

Many dog owners make the mistake of guessing their dog's size based on breed alone. Unfortunately, dogs come in all shapes and sizes, even within the same breed so there is no one-size-fits-all approach. Taking time to measure your dog properly can help you avoid returns, ensure maximum comfort, and find a coat that keeps your pet warm, dry, and happy on every walk. 

In this guide, we'll show you exactly how to measure a dog for a coat and how to choose the perfect size.

Why Proper Measurement Matters

A dog coat that is too small can restrict movement, rub against the skin, and make your dog uncomfortable. Conversely, a coat that's too large may slip, twist, or fail to provide weather protection. 

A properly fitted coat should:

• Cover your dog's back comfortably

• Allow free movement of the legs and shoulders

• Sit securely without slipping

• Provide warmth without causing overheating

• Stay clear of toileting areas

Getting accurate measurements is the best way to ensure your dog enjoys all these benefits. A well-fitting coat should cover the back without extending over the tail and allow natural movement around the chest and shoulders.

What You Will Need

To begin measuring your dog for a coat, you will need:

• A soft tape measure

• Some treats to keep your dog still

• A pen and paper (or your phone) to record measurements

For the most accurate results, measure your dog while they're standing naturally on all four legs. If your dog is particularly active, having another person offer treats while you measure can help you get more accurate results.

How To Measure Your Dog For A Coat

Step 1: Measure Your Dog's Back Length

Back length is the most important factor when measuring your dog for a coat. It is the primary measurement used by many coat manufacturers to ensure the perfect coat fit for a dog. 

To measure:

• Locate the base of your dog's neck where their collar naturally sits.

• Measure along the spine to the base of the tail.

• Do not include the tail itself in the measurement.

Be sure to keep the tape measure straight along your dog's back and avoid pulling it too tightly. This measurement will give you the foundation for selecting the correct coat size for your dog.

Step 2: Measure the Chest Girth

The chest girth is often the second most important measurement for a dog coat. This is particularly the case for broad-chested breeds such as Bulldogs, French Bulldogs, Staffies, and Pugs.

To measure:

• Wrap the tape measure around the widest part of your dog's chest.

• This is usually just behind the front legs.

• Ensure the tape is snug but not tight.

A coat should fit comfortably around the chest without restricting breathing or movement.

Step 3: Measure the Neck

Some dog coats also use neck measurements to ensure a comfortable fit around the collar area.

To measure:

• Wrap the tape measure around the base of the neck.

• Measure where your dog's collar would normally sit.

• Leave enough room for two fingers between the tape and your dog's neck.

This helps prevent rubbing and ensures the coat sits comfortably during walks.

What If Your Dog Falls Between Sizes?

It's common for dogs to fall between standard sizes.

If this happens:

• Prioritise the chest measurement for comfort.

• Consider sizing up if your dog has a deep chest or thick coat.

• Check the manufacturer's size guide before purchasing.

Many dog coat specialists recommend choosing the larger size when a dog falls between measurements. This allows more movements for dogs in winter coats that may be worn over thick fur.

Understanding Dog Coat Sizes

Most dog coats are available in a range of sizes, including:

• Extra Small (XS)

• Small (S)

• Medium (M)

• Large (L)

• Extra Large (XL)

However, there is no universal sizing standard across brands, meaning a medium in one range may fit differently from a medium in another. That's why measuring your dog is always beneficial. 

Common Measuring Mistakes to Avoid

To get the best fit when measuring your dog for coast, make sure to avoid these common errors:

Measuring While Your Dog Is Sitting

Always measure when your dog is standing naturally. Sitting can shorten the back measurement and lead to an incorrect size.

Guessing Based on Breed

Not all Labradors, Cockapoos, or Dachshunds are the same size. Individual measurements are far more accurate than breed averages.

Pulling the Tape Too Tight

The tape should sit comfortably against your dog's body without compressing the fur.

Ignoring the Size Guide

Every coat manufacturer may have slightly different sizing, so always compare your measurements against the specific product guide.
