Black nylon muzzle for training. - Size: 2 - Color: Black - Material: Nylon Purchased a few years ago at an animal hospital for 1500 yen. I have a Shiba Inu, and I bought it because I was recommended to get it to get him used to it in case he bit someone because he hates the vet, but I never used it. The diameter of the muzzle is 8cm. The length of the fastener is adjustable. Opened for photography. Thank you for looking.
