How to Measure Your Dog

Chest Girth
The chest girth is the most important measurement when choosing dog clothing.
Measure around the widest part of your dog’s chest, usually just behind the front legs and over the back. If your dog has a thick or fluffy coat, allow a little extra room for comfort.
If the chest measurement isn’t right, the jacket won’t fit properly regardless of the back length.
Length
Measure from the base of the neck, where the collar naturally sits, to the base of the tail.
Back length is commonly used when sizing dog clothing, but it should always be considered alongside the chest measurement. Your dog should be standing when measured, as sitting can add extra centimetres and affect sizing accuracy.
Neck
Measure around your dog’s neck where their collar would normally sit.
This measurement is particularly important for breeds with larger necks, such as Pugs and Bulldogs, or narrower necks, such as Greyhounds and Chihuahuas.
Choosing the Right Size
Before purchasing, keep these tips in mind:
Always Measure Your Dog
Avoid estimating your dog’s size based on appearance or breed. Measuring only takes a few minutes and provides a much more accurate fit.
Consider the Fabric
Different materials fit differently. Knitted fabrics and stretch materials may provide more flexibility, while structured fabrics can offer a firmer fit. Always consider how the garment will feel when your dog is walking, running and resting.
Between Sizes?
If your dog’s measurements fall between two sizes, we generally recommend choosing the larger size for a more comfortable fit.
Check the Style
Not all dog clothing is designed the same way. For example, coats are often longer and provide greater coverage, while jackets may sit higher on the body. Always refer to the product description and images when comparing styles.
Don’t Rely on Weight Alone
Just like people, dogs come in many different shapes and proportions. Two dogs of the same weight can require completely different sizes, so measurements are always the best guide.
