Very lightweight muzzle. Allows dog to drink water. Always remember: space of an index finger width should be left between muzzle and a dog's nose. Sometimes owners attach for example few rounds of coban elastic bandage around the muzzle to protect skin of nose bridge. This model has been quite popular with smaller than greyhound size hounds. Lightweight muzzle we're having also in two lengths, standard and standard plus. Standard plus is 2cm longer than standard one. In the second photo it is pretty obvious that fishing is prohibited ;).
