Find the Right Size for Your Dog
Getting the fit right matters. A well-fitted harness gives your dog real support. Too loose and it won't hold, too tight and it won't be comfortable. Measure your dog before ordering, and when in doubt between two sizes, go up.
How to Measure Your Dog
You need two measurements: chest girth and belly girth.
- Chest girth: wrap a soft tape measure around the widest part of your dog's chest, just behind the front legs. Make sure you can fit two fingers underneath.
- Belly girth: measure around the widest part of your dog's belly, roughly at mid-body.
Take the measurement while your dog is standing. If your dog can't stand without help, do your best to support them gently, or measure them lying down and add 2 to 3cm.
Size Chart
| Size | Chest Girth | Belly Girth | Typical Breeds |
|---|---|---|---|
| S | 45 - 58 cm | 40 - 55 cm | Beagle, Cocker Spaniel |
| M | 58 - 72 cm | 55 - 68 cm | Labrador, Border Collie, Chow Chow |
| L | 72 - 88 cm | 68 - 84 cm | German Shepherd, Golden Retriever, Rottweiler |
Not for very small dogs. Size S starts at 45 cm chest girth. Toy breeds like a Pomeranian or Chihuahua are too small for this harness.
Six Adjustment Sliders
Every harness comes with six adjustment sliders across both pieces, three on the front and three on the rear. This means the size chart is a starting point, not a ceiling. Most dogs fit comfortably within a size even if their measurements fall slightly outside the range.
