Size Guide
Find the right fit
It's easier than you think. All you need is a measuring tape, or a string and a ruler.
How to measure
Measure around your dog's chest, right behind the front legs where the dog is widest.
💡 Keep in mind: Measure when your dog is standing up. The tape should be snug but comfortable – you should be able to fit two fingers under the tape.
Important: Our breed examples are only guidelines. The same breed may need different sizes depending on body type, weight, and build. Always measure your dog first.

🤔 Is your dog between two sizes?
If your dog falls between two sizes, we usually recommend choosing the larger size. The harness can be adjusted tighter, but it can't be made larger than the maximum measurement.
