Dog Collar Size Guide - Inches

When measuring for either a dog collar, you are looking to measure the upper neck (A) where the neck naturally tapers, as this is where the collar should fit.
We provide an indication of size by breed, but please do not take it as correct for all breeds.
Dogs come in all shapes and sizes, the weight provided is just a guide and to highlight the strength test limits for our collar.
Two finger rule, it is a good method to leave some space around the neck when fitting the collar.
If your pet is between sizes, select the next size up.
