Measure around the mid-lower part of your dog’s neck — where the collar will sit.

For comfort, allow 2 fingers of space (1 finger for fluffy coats).

We do not recommend measuring an existing collar for sizing accuracy.

Measure around the widest (bottom) part of your dog’s neck, to ensure the harness sits on the sternum.

Measure the girth around the deepest part of the chest, behind the front legs.

Measure around the widest part of your dog’s head — just in front of the ears.

This measurement ensures the collar can slip on comfortably over the head.

This measurement is required only for our Limited Slip collar.
