1- -Dog-friendly Material - This Dog Muzzle is constructed of innovative thermoplastic elastomer material commonly used in fitness equipment. Therefore, it is not only soft, lightweight, and comfortable, but also durable, environmentally friendly, non-irritating odor, and for fast and easy cleaning. That means you can spend less time cleaning the small medium large dog muzzle up after your adventure, and more time playing with your furry friend. 2- -Boat Design for fewer pressures: Unlike other dog mouth covers which let the dogs nose hold up the whole muzzle under the action of gravity, this dog muzzle basket's extension part to the cheek can let both cheeks clamp the cage muzzle so that the top part of the dog basket muzzle will not closely press the dogs nose, which can reduce the muzzle weight to the nose and protect the dogs nose from rubbing. 3- -Hollowed-out Design for more breathable - Unlike traditional fabric or leather muzzles that cover the dogs nose closely and widely. The whole mussle is designed hollowed out so that your dog will be provided with maximum ventilation. Also, your dog can put its tongue out of the hole on the bottom of the dog mussel to pant and drink freely. You can give treats easily through this opening.
