Welcome to our shop Product Size: XS 9-12cm / S 12-15cm / M 14-20cm / L 18-24cm / XL 22-28cm COMFORTABLE AND BREATHABLE: The practical and reliable dog muzzle is made of high-quality nylon material, designed for a good fit and durability. Lightweight and environmentally friendly, it provides ultimate comfort for your pet. MORE HUMANIZED DESIGN: Different from traditional dog muzzles, the mesh design offers complete mouth protection, allowing enough space for your dog to breathe, pant, and drink water. ADJUSTABLE AND BREATHABLE: Adjustable at the muzzle and neck strap. Keep the muzzle tight enough to control biting but loose enough for freedom to pant and yawn. Most dogs are not used to wearing a muzzle at first, so we need to take the time to patiently allow them to adapt to the muzzle. EASY TO CARRY AND CLEAN: The combination of double Velcro and buckle makes it easy to carry a dog protective cover. Ideal for aggressive and energetic puppies, to be used during training or daily walks in the neighborhood. It can also be machine washed and air dried. Note: 1.
