How do I measure my dog’s neck for a collar?

Use a soft tape measure around the base of your dog’s neck, where the collar sits. Add two fingers of space for comfort and compare the measurement with the HRR size chart.

Where can I find the HRR collar size chart?

The HRR collar size chart appears on each product page next to the 'Size Chart' button, detailing neck circumference, width, and recommended breeds.

What if my dog’s neck size is between two sizes?

Select the larger size for safety and comfort. HRR’s adjustable leather collars allow for small adjustments and soften over time.

Dog Collar Size Chart & Measuring Guide

Ensure your dog’s collar fits perfectly for comfort and safety. Follow HRR’s detailed measuring guide and reference our size chart for Greyhounds, Whippets, and other large breeds.

How to Measure Your Dog’s Neck

Use a flexible measuring tape (or string + ruler).
Measure where the collar naturally rests—just below the jawline.
Add two fingers of space between the tape and your dog’s neck for a comfortable fit.
Match the measurement with HRR’s collar size chart below.

💡 Pro Tip: If your dog falls between two sizes, choose the larger one. HRR leather collars soften slightly with use.
