DOGS CAN PANT AND DRINK: The dog muzzle allows dogs to pant when hot or stressed and to drink water. Suitable for daily walks and extended wear. SHAPE FOR CUSTOM FIT: Similar to a mouth guard, this muzzle can be heat-shaped using warm water to fit various dog nose shapes. Refer to the fitting guide for more information and to select the appropriate size for your dog. IDEAL FOR REACTIVE DOGS: This muzzle allows you to train and reward your dog with treats if they are reactive around other dogs, people, or in new environments such as the vet. STRONG & SAFE: Constructed from durable Thermo Plastic Rubber (TPR), the muzzle helps prevent biting. Features an extra-secure lockable neck strap clip, head strap, and optional collar attachment for added safety.
