How to measure your dog

Take 1 tape measure and 1 dog (and maybe some treats).

Measure neck size for collars

Take measurement round the base of neck, with 2 fingers slag (UC). Then choose the collar size to match the measurement.

(Do not measure old collar.)

Measure girth for harness / apparel

Take measurement of the largest part of the chest (LC).

Girth is slightly behind the fore legs (not at the fore legs, 'arm pits').

Then choose the gear that matches your measurements.

Measure torso for apparel

Measure from the base of the neck to the base of the tail (L).

Choose the apparel that matches your measurements.
