How Should a Dog Coat Fit? A Complete Sizing Guide

4th Jan 2026

Getting the right fit is essential when choosing a dog coat. A poorly fitting coat can be uncomfortable and ineffective, while a well-fitted coat will keep your dog dry and happy.

Here’s how to make sure your dog coat fits properly.

Key Areas to Check

A dog coat should:

  • Cover the dog’s back without being too long

  • Fit comfortably around the chest

  • Allow free movement of the legs

  • Sit securely without slipping

The coat should not rub, twist, or restrict your dog’s natural movement.

How to Measure Your Dog

To get the best fit, measure your dog while they’re standing:

  1. Back length: From the base of the neck to the base of the tail

  2. Chest girth: Around the widest part of the chest

  3. Neck (if required): Around the base of the neck

Always compare your measurements to the sizing guide before ordering.

Common Sizing Mistakes

  • Guessing the size instead of measuring

  • Choosing a coat based on breed alone

  • Ordering too large “to allow room”

A properly fitted coat should be snug but comfortable.

Special Considerations for Different Breeds

Some breeds need specially designed coats. For example:

  • Dachshunds need longer coats with adjusted proportions

  • Small dogs may benefit from fleece-lined waterproof coats for extra warmth

Final Thoughts

Taking a few minutes to measure your dog properly can make all the difference. A well-fitting dog coat ensures comfort, protection, and happy walks — whatever the weather.
