What size harness do I need?

You will need to take actual measurements so you know you are getting the correct size harness.

Please Note:

There are no industry standards for harness sizes, so it will not be reliable to use a different brand harness for sizing.

How to take a harness measurement

We recommend using a tailor’s tape to measure (the same as if you were getting measured for a suit). If you do not have a tailor’s tape you can use a piece of string that you then measure along a tape measure. Simply wrap the tape/string around the dog as shown below, pull it “tight”—that measurement will determine what size is best.

Front and Rear Strap Chest Girth

If you are measuring for the Patrol Harness you only need to measure for the Front Chest Strap.

What are the sizes that you offer?

Medium Harness:
Front Chest Strap: 24-31in (61-79cm)
Rear Chest Strap: 22-26in (56-66cm)
Length between straps: 6in (15cm)

Large Harness:
Front Chest Strap: 30-35in (76-89cm)
Rear Chest Strap: 25-30in (64-76cm)
Length between straps: 7.5in (19cm)

Extra Large Harness:
Front Chest Strap: 32- 40in (81-101cm)
Back Chest Strap: 28- 34in (71-86cm)
Length between straps: 8.5in (21cm)

What if my measurement is between sizes?

Due to the complexity of a harness, there are many factors that may determine how to proceed if your measurements do not match, or are on the extreme end, of our harness sizing. We recommend reaching out to our support team for further assistance and to determine if custom sizing is needed.

What size harness should I get for my puppy breed?

We often get questions regarding sizing for specific breeds. While purebreds often fall within breeding standards, there are many factors that can affect sizing and the only way to insure a harness will fit is to take an actual measurement when the dog has stopped growing.

If you do not want to wait until your dog has stopped growing and want to anticipate how large of a harness you may need, pedigree will be your best indicator. If you have access to a full grown dog that is the same sex and from the same parents, but from an earlier litter, those measurements may help. Otherwise, if you only have access to the parents, measuring the parent of that sex is best. Lastly, other than that, your vet may be able to give you an educated guess.

Please note that without actual measurements there is no foolproof way to estimate a harness size and you may have to purchase another harness as the dog grows.
