The muzzle for our Caucasian Shepherd fits ideally and it seems it is comfortable for the dog to wear as it has soft padding of felt. If all the measurements are taken correctly, the dog can pant with the tongue out, drink, eat, sniff. We ordered the muzzle with a quick release buckle, it makes the first accustoming easier, as you can take the muzzle off fast. Everything in one. Anyway, it can be just recommended. You can hardly buy such muzzle in usual shops - not at such perfect prices. I will return here again with pleasure! Thank you so much and best regards
