This wireless dog fence system combines boundary control and training functionality in one comprehensive solution. The adjustable wireless boundary extends up to 722 feet with 20 customizable levels, allowing you to create a safe containment area for your pet in yards, farms, or other outdoor spaces. When your dog approaches the set boundary, the system automatically activates warning and correction signals to guide them back to the designated zone. The training collar features three correction modes: beep, vibration with 18 adjustable levels, and static shock with 18 adjustable levels. This flexibility allows you to choose the appropriate training method based on your dog's temperament and training needs. The system supports up to three dogs simultaneously, enabling you to manage multiple pets individually or together. The receiver collar is suitable for dogs three months or older weighing at least eight pounds. Built with IP68 waterproof protection, the receiver collar withstands rain, splashing, and outdoor conditions. Both the transmitter and receiver feature rechargeable batteries that provide extended operation between charges. The transmitter houses an 850mAh battery while each receiver contains a 300mAh battery, ensuring reliable performance for daily pet management and training sessions.
