[Free Panting Muzzle for Flat-faced Dogs] - This barkless muzzle features a three-hole design to provide dogs with a wider field of view and unobstructed breathing. The design allows the tongue to protrude slightly for heat dissipation while preventing full mouth exposure to reduce the risk of accidental ingestion. Dogs can breathe, drink, and accept food while wearing the muzzle, which helps prevent biting, chewing, and licking. Suitable for use during vet visits and grooming sessions. [High-Quality Material] - Constructed from soft, natural, non-toxic silicone, this pet muzzle is durable and comfortable to wear, minimizing the risk of skin irritation or bruising. [Applicable Breeds] - Designed for short-snout dog breeds such as French Bulldogs, English Bulldogs, American Bulldogs, Pugs, Shih Tzu, Boston Terriers, Pekingese, Bully breeds, and Tibetan Spaniels. [Easy to Clean] - Unlike fabric muzzles, this silicone muzzle resists food residue and dirt buildup. Simply rinse with water to maintain cleanliness. [Size Selection] - Please measure your dog carefully before purchasing. Refer to the size guide in Figure 3 and follow the included instructions for proper fit.
