This duvoplus muzzle is made of strong and durable rubber for optimal safety. It keeps your dog's jaws closed to prevent biting, nipping and barking, while giving your dog enough room to drink and pant. The front of the muzzle can be opened to allow your dog to eat and drink easily. The muzzle is comfortable thanks to its ergonomic, flexible shape and soft neoprene padding around the chin. For added security, you have three placement options. Secure the straps with the adjustable buckle and tighten as necessary. Do not overtighten the muzzle! Under the chin is a handy clip where you can attach the muzzle to your dog's collar. There is also an additional safety strap on the top of the muzzle that can be attached to the D-ring using the carabiner. Strong, durable rubber for optimal safetyErgonomic and flexible for additional comfortSoft neoprene padding on the sides and chinThe front of the muzzle can be opened to allow your dog to eat and drink easilyThree attachment options
