Who We Are & What We Care About At Modus, we're passionate pet lovers who have been designing innovative, pet-friendly devices for years. From anti-barking devices to anti-pulling solutions and training collars, our mission is to help pet owners manage unwanted behaviors while ensuring their pets' well-being. We care about more than just effectiveness—we prioritize safety, comfort, and humane solutions for your furry friends. What Makes the Modus Automatic Anti-Barking Device Special? The Modus Automatic Anti-Barking Device uses advanced ultrasonic technology, enhanced with a unique recording function, AI recognition, and irregular frequency modulation. It smartly identifies your dog's barking and filters out other dogs' barks, reducing false triggers and ensuring effective training. Thanks to frequency conversion technology, dogs won't easily get used to the sound, making the device more effective over time. With continued use, your dog will learn that calm behavior leads to no punishment, forming a positive conditioning reflex. For best results, we recommend using this device indoors with just one dog at a time. The device features a clear LED indicator to show its status and can operate while charging. After a 3-hour charge, it works for up to 15 days. Important Notes: Not suitable for dogs under 6 months or over 8 years old. Not for aggressive dogs. Not recommended for dogs with hearing impairments. Consistent use, along with commands and positive reinforcement, is key for long-term success.
