Size Guide

Measure your dog’s back length from the base of the neck, near the collar, to the base of the tail.

Size	Back Length
XS	10–13 in (25–33 cm)
S	13–17 in (33–43 cm)
M	17–20 in (43–51 cm)
L	20–23 in (51–58 cm)

For the best fit, always choose the size based primarily on your dog’s back length rather than weight.

How to Choose the Right Size

Measure your dog’s back length while standing.
Make sure your dog is standing naturally and not sitting or curled up.
Use weight only as a secondary reference.
Follow the manufacturer’s fitting instructions before use.
Check that your dog is properly supported and secure inside the carrier.

Important: Always select the correct size based on your dog’s back length and weight range before use.
