An adjustable muzzle for use on an animal. The muzzle includes a muzzle body having a flexible webbing with two strap channels for a semi-flexible strap. The strap is threaded within the channels and forms an adjustable loop that extends from the muzzle body to secure the snout of the animal, which allows the muzzle body to conform and tighten around the snout. Strap ends extend from the rear of the muzzle body, each end having an adjustable buckle. When the buckles are connected together, the strap forms an adjustable rear collar loop around the neck of the animal. The strap is rigid enough to allow the handler to place the muzzle on the animal by merely holding the straps, but flexible enough to slidably engage with the buckles to adjust the effective length of the strap around the animals neck and snout.
