How To Accurately Measure Your Dog or Cat
Use a flexible tape measure or piece of string before choosing your harness or collar size.
1. Measure The Lower Neck (Dogs & Cats)
Measure around the base of your pet’s neck where a collar naturally rests. For cats or thick-coated dogs, gently part the fur so the tape rests gently against the coat.
2. Measure The Chest Girth (Dogs & Cats)
Measure around the widest portion of your dog or cat’s ribcage, approximately two fingers (1.5–2 inches) behind their front legs.
The Two-Finger Fit Rule (Dogs & Cats)
Whether fitting a dog or a cat, always ensure you can slide two flat fingers between the gear and your pet’s coat. This guarantees proper circulation, allows effortless breathing, and keeps adventurous cats or wiggly pups from wriggling out.
