Every time your dog barks, an electronic sensor releases a painless spray of citronella in front of the dog's nose. Your dog will hear it, see it, feel it, and smell it. The first time the dog is sprayed, it will attempt to identify the source of the new odor. The effect of surprise is sufficient to interrupt the dog in its undesirable behavior.

It's called a gentle spray collar because it is easy on your beloved dog. A fearful dog won't be receptive to training. This gentle spray collar readily associates the disruptive effect of the spray to the dog's behavior while not relating it to the master. Citronella bark collars are not cruel and are in fact a leading alternative for pet lovers around the world.
