📏 The Only Sizing Guide You'll Ever Need to Measure Your Dog Correctly

Get the Fit Right the First Time

The most common question we get isn't about style — it's "what size do I order?" Skip the guesswork with this simple, breed-agnostic measuring guide.

Three Measurements You Need

  1. Neck Girth — Measure around the base of the neck where a collar would sit. Add half an inch for comfort.
  2. Chest Girth — Measure around the widest part of the chest, just behind the front legs. This is the most important number for outfit fit.
  3. Back Length — Measure from the base of the neck to the base of the tail along the spine.

Tools You'll Need

A flexible measuring tape works best. No tape? A piece of string measured against a ruler afterward works just as well.

Tips for Accurate Measuring

  • Measure while your dog is standing naturally, not sitting or stretching
  • Keep the tape snug but not tight — you should be able to slide two fingers underneath
  • If your dog is between two sizes, always size up for comfort, especially for growing puppies

Still Unsure?

Every product page on Petaloons includes a breed-specific size chart cross-referenced with these three measurements — use both together for the most accurate fit.
