[Free Panting Muzzle for Flat-Faced Dogs] - This bark muzzle features a three-hole design to provide dogs with a wider field of view and unrestricted breathing. The design allows the tongue to protrude 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 effectively helps prevent biting, chewing, and excessive licking. Suitable for use during veterinary visits and grooming sessions. [High-Quality Material] - Constructed from soft, natural, non-toxic silicone, this pet muzzle is durable and comfortable to wear, helping to avoid 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, Tibetan Spaniels, and other brachycephalic dogs. [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.
