Size guide
Measure once, know their size in everything
All you need is a tape measure and a minute. Measure around your dog's neck, without pulling tight, and we'll tell you their size in every collection. For harnesses, measure their chest too. If they're between two sizes, the finder tells you which fits better.
How do I measure?
Neck
Where the collar sits, without pulling tight. The finder already adds the room each collar needs.
Chest
At the widest point, just behind the front legs. Only needed for harnesses.
What about weight?
It's only approximate: two dogs of the same weight can have very different necks. The neck is the only real measurement.
