A citronella bark collar is a fairly innovative dog training tool. When it is properly fitted to your dog's neck it emits a spray of citronella every time your dog barks. Citronella is a substance that has an offensive odor to dogs but to humans is usually pleasant.
The benefit of the citronella bark collar is that it allows you to train your dog even when you aren't around. The dog receives the spray of citronella even if you aren't home. Many people prefer this type of collar to a more traditional shock bark collar because there is no electric shock with a citronella collar.
Be careful with this type of bark collar. Some dogs learn to bark quickly to deplete the supply of citronella and then have a full day of consequence free barking. Keep the reservoir full and you will be in better shape to change your dog's behavior.
