How to Measure Your Dog for a Collar: A Step-by-Step Guide

Quick Answer

To measure your dog for a collar, use a flexible tape measure around the base of the neck where the collar naturally rests. Add two fingers' width for comfort, and check the fit regularly as your dog grows or changes weight.

Getting the right collar size is crucial for your dog's comfort and safety. A collar that's too tight can cause chafing or breathing issues, while one that's too loose might slip off during walks. Measuring your dog's neck accurately is the first step to ensuring a perfect fit.

In this guide, we'll walk you through the process step by step, including common mistakes to avoid and tips for measuring wiggly dogs. We'll also share a handy size chart and advice on when to re-measure.

Step 1: Gather the Right Tools

You'll need a flexible tape measure (the kind used for sewing) and a treat to keep your dog still. If you don't have a tape measure, you can use a piece of string and a ruler. Avoid using a metal tape measure—it can be stiff and uncomfortable for your dog.

• Use a flexible tape measure for accuracy and comfort.
• Have treats ready to reward your dog for standing still.

Step 2: Find the Right Spot on the Neck

The collar should sit at the base of the neck, just above the chest and shoulders. This is where the neck meets the body, and it's the widest part of the neck. Placing the collar here prevents pressure on the throat and allows natural movement.

• Feel for the dog's shoulder blades—the collar should sit just above them.
• Avoid placing the collar high on the neck, as this can cause discomfort.

Step 3: Measure the Neck Circumference

Wrap the tape measure around the neck at the chosen spot. Keep it snug but not tight—you should be able to slide one finger between the tape and your dog's neck. This gives you the baseline measurement. If your dog is between sizes, round up to the next size for comfort.

• Make sure the tape is level all the way around, not twisted.
• If your dog has a thick coat, measure over the fur to ensure the collar fits over it.

Step 4: Add Two Fingers for Comfort

For a comfortable fit, add about two fingers' width (roughly 2 inches or 5 cm) to the measured circumference. This allows room for breathing, swallowing, and normal movement. The collar should be snug enough that you can't slip it off over the head, but loose enough to fit two fingers underneath.

• Check that the collar isn't too tight when your dog pulls on the leash.
• If you can fit more than two fingers, the collar is too loose.

Step 5: Check the Fit on Your Dog

Put the collar on your dog and adjust it so it sits correctly. You should be able to slide two fingers between the collar and your dog's neck. Watch your dog for a few minutes—if they seem uncomfortable, scratch at the collar, or have difficulty breathing, it's too tight. If the collar can be pulled over their head easily, it's too loose.

• Perform the 'two-finger test' every time you put on the collar.
• Ensure the collar doesn't spin around the neck—it should stay in place.

Step 6: Re-measure Regularly

Dogs grow, gain weight, or lose weight over time. Re-measure your dog's neck every few months, especially for puppies. A collar that fit perfectly last month might now be too tight or too loose. Regular checks prevent discomfort and escape attempts.

• Mark the measurement on your calendar as a reminder.
• When in doubt, re-measure—it takes less than a minute.

Step-by-Step: Measuring Your Dog's Neck for a Collar

1. Prepare the tape measure: Use a flexible tape measure and have treats ready. If using string, have a ruler nearby. Checkpoint: Ensure the tape measure is not twisted before starting.
2. Locate the base of the neck: Feel for the shoulder blades; the collar should sit just above them. Checkpoint: The spot should be where the neck meets the body, not high up near the head.
3. Wrap the tape measure: Wrap it snugly around the neck, allowing one finger to slide underneath. Checkpoint: The tape should be level and not digging into the skin.
4. Note the measurement: Read the number where the tape overlaps. If between sizes, round up. Checkpoint: Write down the measurement so you don't forget.
5. Add two fingers' width: Add about 2 inches (5 cm) to the measured circumference for comfort. Checkpoint: This extra space ensures breathing and movement are unrestricted.
6. Test the fit on your dog: Put the collar on and slide two fingers between the collar and neck. Checkpoint: If you can't fit two fingers, it's too tight; if you can fit more, it's too loose.
