How to Measure Your Dog

To find the perfect ChillyPup fit, grab a soft tape measure and follow the simple steps below:

Neck
Measure around the base of your dog’s neck - the point where their collar naturally sits.

Chest
Measure the widest part of the chest, just behind the front legs.

Length
Measure from the base of the neck (where the collar sits) down the back to the base of the tail.

Make sure the tape measure is snug but not tight, and allow a little room for comfort - especially for fluffy pups!

We know every dog is wonderfully different, so not all styles will fit every shape the same way.

Frequently Asked Questions

How do I choose the right size?

Every pup is unique, so we recommend measuring your dog’s chest and back length before ordering. Each product includes a detailed size guide to help you find the perfect fit. If your dog is between sizes, it’s usually best to size up for comfort.

How do I care for my dog’s coat or jumper?

Our coats and jumpers have been chosen with practicality in mind. Most styles can be gently machine washed on a cool cycle, keeping them fresh and ready for your next adventure. Always check the care label for specific instructions.

Will these coats and jumpers fit my dog’s breed?

We’ve selected a versatile range with sizes to suit small, medium, and large breeds. Whether you have a Chihuahua, a French Bulldog, or a Labrador, you’ll find a cosy fit designed for both comfort and style.

Are they warm enough for winter walks?

Yes. Each coat and jumper in our collection is carefully chosen for quality and comfort, offering warmth without bulk. They’re designed to keep your pup snug during chilly walks, while still being breathable and lightweight for everyday wear.

Can my dog wear a harness underneath?

Many of our coats and jumpers are flexible enough to pair with a harness. Some designs even include convenient access points for lead attachment. Please check the individual product details for guidance.
