Quick answer

Measure your dog's neck at its widest point using a soft measuring tape, then add 2 inches for comfort. This total gives you the collar size to order for a personalized fit. Always double-check with two fingers of slack.

Why accurate neck measurements matter for personalized collars

A personalized collar is made to your dog's measurements, so getting it right the first time saves you from returns and ensures your dog's comfort. Unlike adjustable collars, a custom fit must account for fur thickness, growth, and the width of the collar itself. For example, a 2-inch wide tactical collar sits differently than a 1-inch collar, so the measurement method stays the same but the added allowance may need slight adjustment for very small dogs.

Tools you'll need

You don't need special equipment—just a soft measuring tape (or a piece of string and a ruler), a helper if your dog is wiggly, and a treat to keep your dog still. Avoid using a metal tape measure; it doesn't contour to the neck and can give a false reading.

Step-by-step: Measuring your dog's neck at home

  1. Step 1: Gather your tools and treats: Use a soft measuring tape or a piece of string and a ruler. Have treats ready to reward your dog for standing still. Checkpoint: Ensure the tape is flexible and not stretched.
  2. Step 2: Position your dog: Have your dog stand comfortably. If possible, have a helper hold your dog steady while you measure. Common mistake: Measuring while your dog is lying down or sitting can compress the neck and give a smaller reading.
  3. Step 3: Find the widest point: Locate the widest part of your dog's neck, usually just behind the ears and above the shoulders. This is where the collar will sit. Checkpoint: For dogs with thick fur, part the fur gently to ensure the tape is against the skin, not just the fur.
  4. Step 4: Wrap the tape: Wrap the measuring tape around the neck, keeping it snug but not tight. You should be able to fit two fingers between the tape and your dog's neck. Common mistake: Pulling the tape too tight, which can make the collar uncomfortable.
  5. Step 5: Record the measurement: Note the measurement in inches. If you used a string, lay it flat against a ruler to get the number. Checkpoint: Measure twice to confirm accuracy.
  6. Step 6: Add allowance for comfort: Add 2 inches to the neck measurement for a comfortable fit. For example, a 16-inch neck becomes an 18-inch collar size. Common mistake: Forgetting to add allowance, resulting in a collar that's too tight.
  7. Step 7: Choose the right collar width: Consider your dog's size and activity level. Wider collars (2 inches) offer more control for large dogs, while 1-inch collars are lighter for smaller dogs. Checkpoint: Ensure the collar width is proportionate to your dog's neck size.
