This is a harness previously used by my late dog, a Labrador weighing around 30 kg. Size 4 The magic marker writing is faded, but it appears to be size 4. A: Girth around the chest, near the base of the front legs: 72-80cm, adjustable with Velcro B: Distance from the top of the right front leg base to the top of the left front leg base: 50cm I checked the website where I bought it, and it seems they no longer carry this color. It's a bright pink. It's old, but very durable, and the harness itself is still perfectly usable. The metal ring where the leash attaches shows some wear, but I don't think it will break. Please purchase this if you don't mind the age and some minor dirt. #BjorKis #Harness #LargeDog #Walk
