- Size XXL (Circumference: 12.25 - 13.75 inches, Length: 3.25 - 4 inches) : This large dog muzzle is ideal for breeds such as Golden Retrievers, Labradors, and German Shepherds. Not suitable for aggressive or highly anxious dogs. Measure your dog's snout circumference and length according to the size chart or video. If your dog's measurements are between sizes, SIZE UP for the best fit. For dogs with longer snouts, like Dobermans, base your choice on both circumference and length. Ensure the muzzle fits comfortably, with no contact at the nose edge. - Dedicated Customer Support : If you encounter any sizing or quality issues before or after your purchase, we are here to help. We aim for your satisfaction and our muzzles come with a detailed instruction manual—please read it thoroughly before use. - Training for Comfort : It is normal for dogs to resist wearing the muzzle initially. Use positive reinforcement methods, including treats and praise, to help your dog adjust gradually. Refer to the instructional video for tips on reducing fear and aiding adaptation. Supervision is required, as the muzzle is not designed for extended wear. - Odor Management : Due to sealed shipping, the muzzle may have a slight smell. To remove this, air it out in a cool, well-ventilated area for a few days or wash it with mild detergent and air-dry. Our muzzles are non-toxic and safe for your pet. - Addressing Bad Habits : With its semi-enclosed design, this muzzle prevents biting and discourages chewing on furniture or eating debris. Remember that while it helps with restraint, changing behavior requires patience and training. - Humane Design : This soft muzzle allows your dog to pant and drink easily, making it perfect for vet visits, walks, grooming, and other activities. - Enhanced Ventilation and Comfort : Featuring breathable mesh and an open-front design, this muzzle ensures maximum ventilation, minimizing overheating and nose irritation during play. - Quick and Easy to Use : Equipped with an adjustable neck strap and quick-release buckle, this muzzle can be put on in just 30 seconds.
