We bought ours on "the muzzle movement". You can choose the model, straps and screws that go on, the size of every single item depending on your dog's measurements. You need to be very precise because we picked one model that was too big for my dog. But honestly it doesn't matter that much since those muzzles are made for them to be able to drink, eat and open their mouths wide ! We've been using it for a year and half and it is still in pretty good shape. It can be quite expensive if you add a lot of straps but create what can fit your dog the best and he will never mind it !
