Desensitize your dog to the stimulus
If your dog barks at specific triggers, gradually get your dog accustomed to whatever is causing them to bark. Start with the stimulus (the thing that makes them bark) at a distance. It must be far enough away that they dont bark when they see it. Feed them lots of good treats for maintaining eye contact with you and not barking. Move the stimulus a little closer (perhaps as little as a few inches or a few feet to start) and feed treats. If your dog starts barking, you ‘ve gotten too close to the stimulus.
Don ‘t be stingy with treats. For example, if you need to pass by another dog on your dog walk, keep some high-value treats in your hand and feed them constantly as you walk quickly by the other dog and then stop once there is enough distance between your dog and the other dog.
Ask your dog for an incompatible behavior
When your dog starts barking, ask them to do something thats incompatible with barking. Teaching your dog to react to barking stimuli with something that inhibits them from barking, such as lying down on their bed.
Make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a dog who is less likely to bark from boredom or frustration. Depending on their, age and health, your dog may require several long walks as well as a good game of chasing the ball and playing with some interactive toys.
