This 2-in-1 dog training collar combines remote-controlled training with automatic bark control in one versatile system. Designed for small to medium dogs weighing 5.5 pounds or more, it features three adjustable training modes including beep, vibration, and static shock, each with eight intensity levels to customize correction based on your dog's temperament and behavior. The remote control provides effective training at distances up to 3300 feet, making it ideal for both indoor training and outdoor activities like park visits or hiking. The automatic bark control mode operates hands-free with a progressive correction cycle that begins with beep, advances to vibration, then static shock before entering sleep mode for safer operation and improved battery efficiency. The system supports up to three channels, allowing you to train multiple dogs simultaneously or individually. The IP68 waterproof receiver ensures reliable performance in rain, snow, or wet conditions, while the rechargeable battery provides long-lasting daily use. The collar features a clear HD display for easy monitoring and adjustment during training sessions. Constructed from durable ABS material, this training system helps reinforce commands, reduce excessive barking, and address unwanted behaviors effectively. The adjustable sensitivity levels and multiple training modes allow you to find the right balance for humane and effective training tailored to your dog's specific needs.
