📐 How to Measure Your Dog's Neck

Simple 3-Step Process:

  1. Get a Measuring Tape: Use a soft measuring tape (like for sewing)
  2. Measure the Middle of the Neck: Wrap the tape around the middle of your dog's neck where you want the collar to sit
  3. Use the Exact Measurement: Don't add any slack - we'll handle the proper fit!

Pro Tip: You should be able to fit two fingers comfortably between the collar and your dog's neck.

❓ Sizing FAQs

What if I'm between sizes?

If your dog's measurements fall between two sizes, we recommend going with the larger size for comfort. Remember, we offer free lifetime resizing!

My dog is still growing. What size should I order?

Order the size that fits your dog now. As they grow, use our free lifetime resizing service to adjust the collar to their new size.

Can I exchange if the size doesn't fit?

Yes! We have a 30-day no-hassle exchange policy. Plus, all fitted collars come with free lifetime resizing.

Do different collar styles fit differently?

No, all our collar models (Caesar, Magnum, Capone, etc.) use the same sizing chart. A 1" Medium fits the same across all styles.

What's the difference between fitted and adjustable collars?

Fitted collars are custom-made to your dog's exact neck measurement for a perfect fit. Adjustable collars have a range of sizes. We recommend fitted for the best look and comfort.
