Size (outside measuring): Width 5 cm (approx 2"). Collar closed: 36 cm (14,2")
How to choose the right size The measure you choose here, is the length of the leather piece of the collar, not including the D-rings. The D-rings adds additional 3 cm (1,2") to the overall length. If you want the collar to pinch when the dog pulls, choose a size that is 3-4 cm (1,2-1,6") smaller than your dog's actual neck size. If you don't want the collar to pinch then the dog pulls, choose a size that is 1-2 cm (0,4-0,8") smaller than the dog's actual neck size.
