I bought the muzzle for my father's Labrador, he is 9 years old. A dog doesn't bite, but my father is an elderly person, so I've got it just in case. The parcel arrived on the 12th day after ordering. I accurately took needed measurements, but still it's unusual to put a muzzle on the dog. When tighten the strap the muzzle is on dog's eyes, but anyway I will try to put it on again. Quality is great! Highly recommended!
