I have bought this muzzle as it is not like any common on the market that would suit my outsized Border Collie that was advised to wear a muzzle when out because of his hyperactivity. The product is made individually and when came turned out to be a perfect fit and made of very quality leather. My initial fears were for the hardness and weight of the muzzle in general that could cause discomfort for the dog. But any of them did not prove and it fitted very well and seemed to be made to make a dog feel maximum comfortable.
The impressions of the dog are mixed, as you can imagine. On the one hand he does not like to wear a muzzle in general, but this new one seems to bother him less then the previous one. And taking into account that the previous commercial one bothered him covering with his eye with the middle strap, the new tailor made wire muzzle seems more tolerable.
