I LOVE LOVE LOVE this muzzle. I have a 200 pound Saint Bernard who has some behavioral problems with meeting new people. I purchased this muzzle because I wanted something that was comfortable for him but secure enough to prevent bad behavior. It is well made and the measurements I sent resulted in a perfect fit! It is easy to put on and he doesnt seem to mind it one bit. Since he has big jowls and a wide snout I needed soemthing that would allow him to open his mouth a bit to be able to breathe. The leather is soft and the felt padding by the nose offers a comfortable fit for him. I no longer feel nervous about introducing him to new people, he has been doing great.
