Giz and Halo MMNB dog apparel size guide showing sizes S through 3XL with neck, chest, back length, weight, and breed guidance

How to measure your dog

  1. Neck: Measure around the base of the neck where the collar naturally sits.
  2. Chest/Girth: Measure around the widest part of the chest, just behind the front legs.
  3. Back Length: Measure from the base of the neck to the base of the tail.

Allow 1–2 cm for comfort and seam allowance. Use body measurements as your primary guide; weight and breed references are approximate. If your dog falls between sizes, choose the larger size.
