There are a few ways to reduce the amount your dog. Dogs can bark for few reasons. Perhaps they want your attention, or they might be fearful or anxious and are barking to alert you. Also, barking habits can also be very breed specific. Some breeds are known to be more vocal than other breeds. It's important to try and understand why they are barking to then initiate the proper course of action to address their barking habits. If you believe they are barking for attention, one idea is to make sure you are not rewarding their barking by distracting them with a treat or playtime. By doing this, you are teaching them that if they bark, the dog will get what they want. Instead, you might want to consider a couple items. First, is the dog getting enough exercise or releasing their energy. Increase their stimulation by walking them more, playing with them, or socializing them with other dogs or humans. This added stimulation may reduce their need for attention. If they are barking because they are fearful or anxious, think about what is happening or what the environment is that may be cause their fear or anxiety. Then, try and change the environment or situation so the dog feels safe. One action that may help is providing a safe place for your dog, such as a dog crate or dog bed, so they know exactly what to do when they are afraid or anxious. Training them to go to their safe place may provide the comfort they need to reduce their barking habits.
