Size Guide

We understand one size does not always fit all. This sizing chart is meant to give a general idea of the collar size in relation to certain breeds. Because each dog is unique, we offer standard and custom sizes for you and your pup. 

Please contact us at info@wigglywoos.com if you have any questions in regards to your collar size, if your dog is on the cusp or you are not sure which width to choose. 

If you don't see a standard size that works for you, contact us and we will outfit your dog with the perfect fit.




How to measure your dog

Dog Collar

Loosely measure the dog’s neck with a soft tape measure where the collar would normally sit, sliding two fingers between the dog’s neck and measuring tape. This should give a comfortable collar size for your dog. Or you can measure his neck snugly and add two inches. 

Dog Harness

Measure the chest girth of your dog (around the body) right behind the forearms. 

If you do not have a soft tape measure, you can use a string and then measure the string with a rigid ruler. 

Harness Sizes:

XS: 12-16 inches (30cm - 40cm)
Small: 15-21 inches

Med: 19-26 inches (48cm - 66cm)
Large: 25-34 inches (64cm - 86cm)
XL: 33-46 inches (84cm - 117cm)
