Around the chest, just behind the front legs. Measuring guide.
Optional. Each fully grown dog of a named breed adds to that breed’s measured chest range, published on its breed page once twenty are in.
Type the chest girth and the size appears for all 12 harnesses — Julius-K9 · Ruffwear · PetSafe · Kurgo · Blue-9 · Rabbitgoo · Puppia · PetSafe 3 in 1 · Dog Friendly Co · PawSafe · Wonder Walker · Top Paw — with where your dog sits inside each size.
Before you order — the two-finger rule · full measuring guide
- Measure the deepest part of the ribcage, just behind the front legs, with the dog standing.
- Two fingers should slide flat under any strap. A whole hand means it is loose enough to reverse out of.
- Snug against the coat, not pulled tight through it — and re-check after a groom.
Ranges are transcribed from each manufacturer’s own chart. See the full conversion chart or how we check these numbers.
Fitting a harness on a Belgian Malinois
The Belgian Malinois is a high-energy, muscular dog with a deep chest and a powerful, athletic frame. The build is generally square and lean, with a neck that is well-muscled and tapers into the shoulders. There is a notable size difference between males and females, though both maintain a streamlined silhouette.
A durable, multi-point harness is recommended to handle the strength and speed of this breed. A Y-shaped front is preferred to allow for the high-intensity movement and jumping typical of the breed.

How to measure a Belgian Malinois
Measure the chest at its deepest point while the dog is standing squarely. For younger dogs, leave a little room for muscular development in the chest and shoulders as they reach full maturity.
Take a soft tape right around the deepest part of the ribcage, just behind the front legs. Keep it snug against the coat rather than pulled tight — you should be able to slide two fingers under it. That single number, the chest girth, is what every brand on this page sizes by. Weight is only ever a tie-breaker. The full measuring guide covers the mistakes that send harnesses back.
