FIT THE DOG

How do I measure?

Use the dog’s actual measurements. The guide below shows exactly where the tape should sit for the widest head and neck measurements.

Side-profile dog with a yellow measuring tape over the ears and under the jaw at the widest part of the head
Widest headBring the tape over the ears and under the jaw.
Side-profile dog with a yellow measuring tape wrapped around the neck where the collar sits
NeckWrap the tape where the collar normally sits.

Measure snugly against the dog without pulling the tape tight. We’ll use these measurements to guide the correct build.
