Hello, today I got a muzzle by post, and, of course, I tested it out at once. I suppose it fits well, just sometimes it pushes on a nose a little bit. But Sam has no signs of pushing left. It seems to him that this muzzle fits him better as he accepts it better than his older one. What I like the most is the regulated belts that allow to fasten the muzzle for the best fit. Best regards from Sandra and Sam
