Our Size Woof muzzle is built for large dogs who need a secure but comfortable fit for everyday life. Made from Biothane, it’s fully waterproof, lightweight, and easy to wipe clean. Perfect for daily walks, training, or trips to the park.
We don’t believe in breed-specific muzzles, but as a rough guide, Size Woof was designed with XL Bullys, Rottweilers, Cane Corsos, Mastiffs, and other similar large breeds in mind.
With rust-resistant stainless steel fixings and a design that allows your dog to pant and drink water safely, this muzzle offers both comfort and peace of mind.
