Hover to zoomSize guide & how to measure
Harnesses are sized by the chest (girth) — the measurement around the widest part of the ribcage, just behind the front legs.
How to measure
- Stand your pet up squarely.
- Wrap a soft tape around the widest part of the chest, just behind the front legs.
- Keep two fingers under the tape so the fit is snug, not tight.
- If your pet is between sizes, choose the larger one.
| Size | Typical chest / girth | Rough guide |
|---|---|---|
| XS | 28–40 cm | Toy breeds, kittens, very small dogs |
| S | 38–53 cm | Small dogs (e.g. Dachshund, Yorkie) |
| M | 50–68 cm | Medium dogs (e.g. Cocker Spaniel, Beagle) |
| L | 65–85 cm | Large dogs (e.g. Labrador, Boxer) |
| XL | 82–105 cm | Giant breeds (e.g. German Shepherd, Rottweiler) |
Ranges are approximate and vary by style. Always check this product’s Specifications for its exact measurements.
