Improved design to prevent biting, barking, and unwanted chewing This muzzle is great for limiting your dog's ability to bite, chew and bark while still allowing your dog to breathe, pant, and drink water. Its a humane choice for preventing unwanted biting or chewing. See our images for examples. Comfortable Neoprene Padding. Zero Chafing Save your dog from painful chafing and rough straps. Most muzzles are painful and can rub your dogs skin raw. GoodBoy makes a comfy, humane muzzle that keeps your dog happy. High Quality Sliders. No Cheap Buckles The sliders ensure that your dog cant loosen the straps while giving you more control over the exact fit. Plus, loose ends can be secured with a hook and loop fastener, unlike with buckles.
