Muzzles allow aggressive dogs to get out in public without putting themselves, other animals or people at risk.
Things to consider: Behavior around other animals and people, how the dog handles new people and animals, and training needs.
Safe Approach - Muzzles allow owners of dogs who can be aggressive and antisocial (or at least unpredictable and uncontrollable) to get them the outdoor exercise they need without putting other dogs and owners at risk.
Just In Case - Use a muzzle on your dogs whenever introducing new elements into your home for the first time, be they babies, other dogs, new animals of other species, guests, or delivery people and service providers. If your dog has enough room in the muzzles to drink water and take a small treat out of your hand, you can have the new "stranger" let your dog smell his hand, then give him one of his favorite dog treats. That ought to warm him up to any newcomer in no time. Then you can take the muzzle off.
Training Uses - Muzzles are not just for your dog, they are for you too. We will explain: dog training is always a two-way process, and the owners have to train themselves to handle the dog every bit as much as the dog has to be trained to be handled. Muzzles, even used on placid and friendly dogs, can help you maintain firmer control of your dog during this crucial training period until you have developed enough confidence in your ability to handle the dog that you will not need the muzzles.
