BarkLimiter Deluxe, built with proven Tri-Tronics dog training technology, is the worlds first intuitive electronic bark correction device. It uses accelerometer-based bark identification to distinguish between barking and other vocalizations. This virtually eliminates false corrections caused by paw scratching or scraping of external surfaces, or other noises like the barks of nearby dogs. So your pet wont receive false corrections for the barking of other dogs in the neighborhood, the kennel or doggy daycare.
