Trekker & FTD Harness Size Chart

Measuring for your dog for a harness:

  • Ensure your dog is standing still
  • Measure using a fabric tape measure or string
  • Measure the chest immediately behind the forelegs and immediately in front. Both sizes should fit within the adjustable range. 


Size Neck Chest Fits
XS 20-28cm 32-47cm  - dogs up to 5kg
27-35cm 38-52cm  - dogs up to 17kg
32-42cm 43-59cm  - dogs up to 32kg
37-47cm 50-74cm  - dogs up to 41kg


Note: If your dog's measurements overlap two sizes, then unless you expect your dog to continue growing, or if your dog is large set, the smaller of the two sizes is probably the better choice.
