How to Measure Your Dog's Neck for a Collar

Getting the Perfect Fit

A properly fitted collar is essential for your dog's comfort and safety. Follow these simple steps to get an accurate neck measurement before ordering.

What You'll Need

  • A soft fabric measuring tape (preferred)
  • OR a piece of string and a ruler

Step-by-Step Instructions

  1. Position your dog. Have your dog stand or sit calmly in a natural, relaxed position with their head up.
  2. Locate the base of the neck. Find the area where the collar will naturally rest — this is typically at the base of the neck, just above the shoulders.
  3. Wrap the measuring tape. Wrap the soft measuring tape snugly around the base of your dog's neck. Make sure it lies flat and is not twisted.
  4. Check the fit. The tape should be snug but not tight — you should be able to slip two fingers comfortably between the tape and your dog's neck.
  5. Record the measurement. Note the number where the tape meets. This is your dog's neck circumference.

Sizing Tips

  • Puppies: Measure frequently as puppies grow quickly. Choose an adjustable collar to accommodate growth.
  • Thick-coated breeds: Measure with the coat in its natural state. You may want to add an extra half inch for comfort.
  • Between sizes? Always size up for comfort and safety.
