Pet Collars & Harnesses Sizing Guide

🦮 Collars, Harnesses & Leashes Sizing Guide

A properly fitted collar sits snugly without restricting breathing or movement. For harnesses, chest girth is the primary fit driver — neck girth is secondary for most styles. Always measure before ordering.

📏 How to Measure Your Pet

  • Neck Girth (Collars): Measure where the collar naturally rests and add 1–2" for comfort. You should be able to fit two fingers between the collar and your pet's neck.
  • Chest Girth (Harnesses): Measure around the widest part of the chest, right behind the front legs. Add 1–2" for comfort and freedom of movement.
  • For Step-In Harnesses: Also measure the distance between the front legs for the most accurate fit.

💡 Tip: Two fingers should fit comfortably under a properly fitted collar. For harnesses, if between sizes, size up — a harness that's too tight restricts movement and causes chafing.
