The duckbill shaped dog muzzle is a great way to shut your dog up and make him look like an idiot at the same time. Oh, you want to bark? Well now you're going to look like a duck. The Duckbill dog muzzle is suitable for most smaller dogs but has an adjustable strap to fit most dogs noses. The quack muzzle is made from 100% environmentally friendly silica gel, and is great preventative to barking, biting, licking wounds, or eating random things out in the yard.
