How to Measure Your Dog’s Neck for a Collar

You’ll Need:

  • A flexible measuring tape (or a piece of string and a ruler)

  • A treat (to help your dog stay calm and still)

  • A notepad or phone to record the measurement

Step 1: Get Your Dog Relaxed

Have your dog stand or sit comfortably. Give them a treat or two so they stay calm during the process.

Step 2: Locate the Correct Spot

Find the base of your dog’s neck, where their collar normally sits — typically just below the jaw and above the shoulders.

Step 3: Wrap the Measuring Tape

Wrap the measuring tape around your dog’s neck at that spot.

  • The tape should be snug but not tight.

  • You should be able to fit two fingers comfortably between the tape and your dog’s neck.

    • (This is called the “two-finger rule.”)

If you’re using string, mark where it meets, then measure that length with a ruler.

Step 4: Record the Measurement

Write down the neck size in inches or centimetres.
For example, “Neck: 15 inches.”

Step 5: Add Comfort Allowance (if needed)

If your dog has a lot of fur, loose skin, or is still growing, add 1–2 inches (2.5–5 cm) to the measurement for comfort and adjustability.
