Manufacturer’s size guide: measure your dog (neck circumference, chest circumference behind the front legs, and back length from the withers to the base of the tail) and compare the measurements with the ranges. If your dog falls between two sizes, contact us with the measurements.
How to measure your dog
Have the dog stand upright, with a flexible tape measure lying flat (or use a piece of string measured against a ruler). “Snug” means in contact with the fur without compressing it.
- Measurement 1 – Neck circumference: just below the throat, where the harness sits, with the tape snug. Also note the measurement with 3 fingers flat under the tape.
- Measurement 2 – Chest circumference: around the widest part of the rib cage, just behind the front legs, with the tape snug. Also note the measurement with 4 fingers flat under the tape.
- Measurement 3 – Back length: from the withers (base of the neck) to the base of the tail. Measure three times and use the average.
- Measurement 4 – Neck circumference at the base: at the thickest part of the neck, with the tape snug, then with 3 fingers inserted (useful for custom sizing).
- Measurement 5 – Belly circumference: at the narrowest point, just in front of the groin, with the tape snug, then with 3 fingers inserted (useful for custom sizing).
To choose a size from the chart, the snug measurements 1, 2, and 3 are sufficient. If your dog falls between two sizes or is outside the standard range, send us all five measurements along with the breed, age, and weight: the manufacturer also makes custom harnesses. If in doubt, include a side-view photo of the dog.
