1) The equipment for measuring

  • Flexible measuring tape (sewing) or string + ruler.
  • Treats to keep the dog calm and standing.
  • An assistant if your dog moves around a lot.

2) Take the 2 key steps

A) Chest circumference (mandatory)

Place the tape measure behind the elbows , at the widest point of the rib cage. The dog is standing straight , breathing normally. Note the measurement in cm .

B) Neck circumference (often useful)

Measure the base of the neck (neck/shoulder junction), where the chest strap passes for head-pull harnesses. Note in cm.

Tip: Measure twice and take the average. For growing puppies, add 2–3 cm of extra space and choose a highly adjustable model.

3) Read our charts & choose the size

Example of interpretation:

  • If your chest measurement is 57 cm and size M covers 50–60 cm, then size M is suitable.
  • Between two sizes (e.g., 60 cm exactly on M 50–60 and L 58–70): sturdy/hairy dog ​​→ L; slim dog → M (if adjustment sufficient).

Still unsure? Write to us from a product page with: breed, chest/neck circumference, weight, age and standing profile photo.

4) Adjust the harness in 60 seconds

  1. Position : the Y -junction must touch the sternum (center of the thorax), never the throat.
  2. Comfort : slide 2 fingers under each strap (neither tight nor loose).
  3. Free shoulders : the strap should not cut into the shoulder blade.
  4. 10-step test : the harness does not rotate, does not ride up the neck, no chafing under the armpits.

For dogs that pull, start with the front leash , then switch to the back leash when the walk becomes more relaxed. See: 15-minute routine .

5) Common mistakes to avoid

  • ❌ Choosing by sight or by weight alone : ​​always measure.
  • ❌ Harness that causes suffocation (junction too high on the throat).
  • ❌ Straps too loose : risk of slipping out backwards.
  • ❌ Ignoring body shape (large chest, dense coat) when you are between two sizes.
  • ❌ Do not re-check the settings after 2–3 rides (the fabric settles).

FAQ – Measurements & Sizes

My dog ​​is between two sizes, which one should I get?
Broad chest/dense coat: choose the largest size . Slender dog: the smallest size if the adjustment range allows.

Should the neck area also be measured?
Yes, if the harness goes over the head . Otherwise, the chest measurement is often sufficient.

How many times should the fit be checked?
At reception, then after 2–3 walks , then weekly for puppies (rapid growth).

My dog ​​marks under its armpits:
Add 0.5–1 cm for ease, check the strap height . If necessary, change size/model.
