Sizing & Fit Guide

Find a supportive, comfortable fit

The right fit helps keep assistance steady and comfortable. Compare your dog’s back, waist, legs, and weight with the chart before selecting a size.

Size Back (cm) Waist (cm) Legs (cm) Dog weight (kg)
S 32 42–56 24.5 6–12.5
M 39 54–68 30 13–17.5
L 44 60–90 35 18–22.5
XL 56 70–100 47 28–37.5

How to choose

  1. Measure your dog while they are standing comfortably.
  2. Compare all measurements with the chart rather than relying on one number alone.
  3. Choose the size that most closely matches the complete set of measurements.

Not sure which size to choose? Send us your dog’s measurements before ordering and we’ll help you compare the options.

Before the first use

  • Check every strap, buckle, and fastening.
  • Adjust the harness so it feels secure without restricting natural movement.
  • Introduce assistance gradually with short, supervised use.
  • Stop if your dog shows discomfort and ask your veterinarian for guidance.

A careful fit is the first step toward more comfortable everyday assistance.
