How do I stop a dog from barking?

There are several steps you can take to stop a dog from barking. First, make sure the dog is not reacting to a sound or person and is instead just being wary or anxious. If that's the case, try desensitizing the dog to the stimulus by rewarding it for ignoring the sound or person. 

If your dog is simply behaving in an aggressive manner toward people, set up a training session with a professional trainer who can help you reinforce more appropriate behaviors.

For general instances of excessive barking, focus on redirecting your dog’s energy and attention. When your pup starts barking excessively, command him to “stop” or “quiet”. If he complies give him treats and praise until he eventually stops on his own accord.

You can also use management methods like creating safe zones where your pup cannot access when guests are over; using leashes whenever possible to prevent undesirable behavior; covering external noise with distractions like classical music; blocking off areas where stray noise could be coming from; setting up playdates with other dogs in neutral locations such as parks - not homes - so as to avoid territorial impulses;

Finally, if none of these measures prove successful in curbing excessive barking – seek veterinary advice. Excessive barking could be caused by medical conditions that must be attended to first prior to commencing any type of training protocol.
