That is the first muzzle I've purchased, so I am not sure I wear it on my dog correctly, but it has already done its job! It stops my German Shepherd Dog from biting another dog and gives me some semblence of peace and control! I will not hesitate to purchase and recommend dog muzzles ever again. I will send anyone who needs it to you! I've been afraid to get fake leather on the internet. But not this time! Real, well done leather. I know if any thing is wrong, its to do with my measurements, absolutely zero to do with quality.
