The DT Systems Bark Boss is a sound-based no-bark device that clips to a dog's collar and triggers a correction tone when the dog barks. It is aimed at small dogs and owners who want to curb nuisance barking without a shock collar. Unlike vibration or spray units, it relies on audible tone only, which some dogs ignore. Owner feedback is mixed: some report quieter dogs within days, while others say their dog learned to bark through it or was unaffected.
