C-Muzzle with Velcro Flaps to Visualize Mouth and Teeth. Safety and Protection. The use of a nylon muzzle is a common everyday necessity in a veterinary practice. Patients can be upset, frightened, and even vicious. However, standard nylon muzzles block access to the oral cavity. The C-Muzzle was developed by a practicing veterinarian to solve that problem. Velcro flaps on both sides of the jaw allow visual inspection and access to the patient’s mouth. SIZE 1
