method 2, number 2

Practice the command. Most dogs are natural barkers and do not need a command to bark at the sound of someone approaching or a sudden noise. The key here is to get your dog to bark on command. To begin, tie your dog up on his leash to a kitchen table leg or on a spot on your fence in your backyard. Hold a treat out to your dog as you back away from him, and then move out of his field of vision.

• As soon as your dog makes a sound, like a whine or a bark, run back to him and praise him with “good bark” or “good [trigger word].” Give him his treat immediately. After repeating this several times, your dog should start to connect your praise of his bark with a reward.
• Once your dog gets comfortable with the bark command while in the same area or spot, move him to different areas in your yard and in your house. You should also test his response to the command when you are walking him or playing together in a public place.
