How to Measure Your Dog for a Collar (and Pick the Right Size)

A collar that's too loose slips over your dog's head on a walk; one that's too tight rubs. Measuring takes a minute and saves a return.

Measure the neck

  1. Use a soft tape measure. No tape? Use a piece of string or a phone charger cable, mark it, then lay it against a ruler.
  2. Measure where the collar sits, around the middle of the neck, not right behind the ears.
  3. Keep it snug, not tight. Write down the number.
  4. Check with two fingers. A well-fitted collar lets two fingers slide flat underneath. For a small dog that's about an inch of room; for a big dog, closer to two.

Already have a collar that fits well? Lay it flat and measure from the buckle to the hole your dog uses. That's the number you need.

Pick a size

Every Muddy Paw collar is fully adjustable, so pick the size whose maximum is at or above your dog's neck measurement.

If your dog measures right at the top of a size, or is a puppy still growing, go up one size so there's room to adjust.
