Woolly Wolf Size Charts

How to Pick the Right Size?

The measurements in our size charts are generally provided in centimeters (cm) and inches (in).

1. Chest girth Wrap the tape measure around the widest part of your dog’s chest, just behind the front legs.

2. Neck girth Measure around the base of your dog’s neck (the widest part), just above the shoulders.

Tips:

Use a soft measuring tape or a yarn and a ruler.
Ensure the tape is snug but not tight.
Compare your measurements to our size charts. ( Notice that each product uses their own size chart ).
When choosing the right harness for your dog, chest measurement plays the most important part.
