How do I measure my dog for the right size?

The sizes of our products use two measuring points: the neck circumference (A), and the chest circumference (B). Measure around your dog's neck and/or chest with a tape measure, leaving two fingers extra space. Look in the tables within which size this circumference (in centimeters) falls.

If the measured circumferences are tight within one size and wider in a size larger, we always recommend the larger size.

We can always help you and are happy to advise you about the sizes. Mail to or send us a DM via Instagram (barx.dogs).

TIP: Don't have a tape measure? You can also use a lace or piece of string and measure it with a ruler.

NOTE: There are different types of harnesses with different sizes!


The adjustable harness is adjustable at both the neck and chest. The table shows the minimum and maximum circumferences in centimeters per size. Does your circumference fall within two different sizes (for example XS and S)? Choose from for the larger/looser size of the two (S in this example).
