Finding the perfect fit ensures your dog stays warm, dry, and comfortable in the field. Follow the simple measuring steps below to choose the right size.
How to Measure Your Dog
Use a soft tape measure and allow for a snug but comfortable fit.
1. Back Length (Topline) – Most Important
Measure from the base of the neck (where the collar sits) to the base of the tail.
This measurement determines the coat size (e.g., 35cm, 45cm, 55cm).
2. Chest Girth
Measure the widest part of your dog’s chest, just behind the front legs.
This helps ensure the coat won’t be too tight or restrict movement.
3. Neck Circumference
Measure the base of the neck where the collar naturally rests.
Useful for coats with adjustable or fixed neck openings.

Fit Tips
- The coat should cover the dog’s back without hanging over the tail.
- Ensure enough room around the chest to allow natural movement.
- Adjustable straps give extra flexibility for growing or active dogs.
- If between sizes, choose the larger size for comfort, especially for winter layers.
