RG Harness 101: How to Measure & Choose the Perfect Fit?
A great adventure starts with a harness that feels like a second skin. If it’s too tight, it restricts movement; too loose, and your dog might perform a disappearing act. To ensure your pup stays secure and comfortable, follow this streamlined guide to getting the perfect measurements every time.
Preparation: Tools & The Golden Rule
Before we dive into the measurements, let's get you set up for success.
1. Grab Your Tools
A soft measuring tape, or a piece of string and a ruler. You can wrap the string around your dog, mark the spot, and then measure it with a ruler.
2. The Golden Rule: "The Two-Finger Space"
When measuring, keep the tape measure snug but not tight. You should be able to fit two fingers comfortably between the measuring tape and your dog’s body. This ensures the harness stays secure without chafing or restricting their breathing.
3. Pro Measurement Tips
Stay Level: For the most accurate data, ensure your dog is standing calm on a level surface. Measuring while they are sitting or lying down will lead to an incorrect fit.
Measure Twice, Order Once: Dogs wiggle! Measure at least twice to ensure your numbers are consistent and accurate before checking the size chart.
Step-by-Step Measurement Guide
Follow these steps and match the illustrations below for the most accurate fit.
Common Measurements of Dog
The most common and important measurements are neck girth and chest girth, which directly impact how well the harness fits and stays in place.
1. Neck Girth
Wrap the tape around the lower part of your dog’s neck, just below where the collar normally sits. Make sure it’s snug but not tight.
2. Chest Girth
This measurement should be taken around the widest part of your dog’s chest, just behind the front legs. The chest girth determines how securely the harness will sit and whether it will stay in place without slipping off.
Additional Data for Specialized Gear
While neck and chest girth are the essentials, our specialized gear and full-body harnesses often feature additional adjustment points for a truly "tailored" fit. For these advanced styles, you’ll want to capture a few more details:
3. Back Length
Run the tape from the base of your dog’s neck to where the belly begins. Keep the tape straight along the spine to measure the back length. This measurement is ideal for harnesses with reinforcement or decorative details along the back. It ensures your dog remains comfortable and that the harness doesn’t interfere with their movement.
4. Belly Girth
Measure around the widest part of your dog’s belly. This is commonly used for harnesses with belly straps to ensure a snug and secure fit, preventing any slipping.
Match Your Data to the Size Chart
Once you have your numbers, it’s time to find the match. You can find the specific Size Chart on every product page:
How to find it: Simply click the "Size Guide" link near the "Add to Cart" button or scroll down to the Product Description(Size Guide).
Pro Tip: The "In-Between" Rule: If your dog’s measurements fall between two sizes, always go one size up. This provides extra room for adjustments and ensures your dog can move (and breathe!) freely.
