[Free Panting Muzzle for Flat-Faced Dogs] - This barkless muzzle features a three-hole design to provide a wider field of view and allow smooth breathing. The design permits tongue protrusion for heat dissipation while preventing the mouth from fully opening, helping to avoid accidental ingestion. Dogs can breathe, drink, and be fed while wearing the muzzle, which effectively helps prevent biting, chewing, and licking. Suitable for use during vet visits and grooming sessions. [High-Quality Material] - Made from soft, natural, non-toxic silicone, this pet muzzle is durable and comfortable, and it will not cause skin irritation. [Applicable Breeds] - Designed for short-snout dog breeds such as French Bulldogs, English Bulldogs, American Bulldogs, Pugs, Shih Tzu, Boston Terriers, Pekingese, Bully, Tibetan Spaniels, and other flat-faced dogs. [Easy to Clean] - Unlike nylon fabric muzzles, this silicone muzzle can be easily cleaned by rinsing with water, making it simple to remove food residue and dirt. [Size Selection] - Please measure your dog carefully before purchasing. Refer to the size guide in Figure 3 and follow the provided instructions.
