• PEACE AND QUIET AT LAST - Say goodbye to non-stop barking and neighbor complaints with our 3-pack of high-efficiency dog bark collars. Perfect for multi-pet households, these collars offer a humane way to train your dogs to remain calm and quiet using advanced sound and vibration technology that effectively interrupts nuisance barking.

• CUSTOMIZABLE TRAINING MODES - Every dog is unique, which is why our anti-bark device features 5 adjustable sensitivity levels and multiple training modes (Beep, Vibration, and Harmless Static Shock). This allows you to tailor the correction level to your dog's specific temperament, ensuring a safe and effective training experience for every breed.

• UNIVERSAL FIT FOR ALL BREEDS - Designed to grow with your pet, these adjustable collars fit small, medium, and large dogs ranging from 8 to 120 lbs. The high-quality nylon strap is durable yet comfortable for daily wear, making it the ideal choice for everything from a tiny Terrier to a massive Great Dane without needing multiple sizes.

• ADVANCED SMART TRIGGER SENSOR - Our upgraded bark collar is equipped with an intelligent barking detection chip that filters out background noises and other dogs' barks. This ensures that the collar only activates when your dog barks, preventing false triggers and providing consistent, fair reinforcement that speeds up the learning process.

• DURABLE & RECHARGEABLE DESIGN - Built to withstand active puppy energy, these collars are IP67 waterproof for rainy walks or backyard play. The long-lasting rechargeable battery power saves you money on expensive replacements, providing up to 15 days of use on a single charge so your furry friends are always protected and well-behaved.
