Size Guide
FIND YOUR PUP’S PERFECT FIT.
One soft measuring tape, two minutes and a few treats. That’s all it takes to pick the right size.
ALL SIZES IN CMBEFORE YOU START
SOFT TAPE
Use a flexible measuring tape. No tape at home? Use a piece of string and a ruler.
STANDING PUP
Measure while your dog stands straight and relaxed, not sitting or lying down.
TWO FINGERS
Keep the tape snug, not tight: two fingers should fit between tape and fur.
HOW TO MEASURE

-
NECK
Measure around the base of the neck, where a collar naturally sits. You need it for collars and harnesses.
-
CHEST
Measure around the widest part of the rib cage, just behind the front legs. The key measurement for harnesses.
-
BACK STRAP
Measure along the back, from the neck line to the chest line.
-
FRONT STRAP
Measure along the breastbone, from the neck line down between the front legs to the chest line.

FIT TIPS
START WITH THE CHEST
For harnesses, start with the chest: pick the size whose range fits your dog, then fine-tune all the straps for a snug fit.
BETWEEN SIZES?
Go for the larger one. You can always tighten the straps, but never make them longer.
GROWING PUPPY?
Pick the size where your puppy sits at the lower end of the range, so there is room to grow.
