SIZE GUIDE
HOW TO MEASURE YOUR DOG?
Every dog can vary in size even within the same breed, which is why it's important to measure them to get it right. If you have any doubts once you've taken the measurements, don't hesitate to contact us at info@dukier.com and we will be delighted to help you find the product and size that best fits your furry friend.

MEASUREMENT A
If it's for a harness or clothing, measure your dog around the lower neck, almost at shoulder level where the harness usually sits.
If it's for a collar, measure your dog's neck at the height where they naturally wear their collar.
MEASUREMENT B
Measure your dog's chest circumference, right behind the front legs.
MEASUREMENT C
Measure your dog's length from the neck to the base of the tail (end of the back).
COLLARS
If your dog is between two sizes, choose the smaller collar for a thinner fit or the larger collar for a wider fit.

They run VERY SMALL, always leave a 2-3cm margin, so we always recommend ordering one size up, keeping in mind that the harness will go underneath the raincoat. If you are between two sizes, always choose the larger one.
