Size guide

Measure your dog’s neck, chest and back to find the best fit for your Anti-Bite Vest. Compare all three measurements with the size chart below.

How to measure

  1. Neck contour

    Measure around the base of the neck, at its widest part, where a collar would sit.

  2. Chest contour

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

  3. Back length

    Measure along the spine, from the base of the neck to the base of the tail.

Use a soft tape measure and keep your dog standing. Leave two fingers of slack - do not pull the tape tight.
