This advanced wireless dog fence system combines an electric fence and a remote training collar into one convenient solution, making it ideal for pet containment and training. With a large LCD screen, setup is easy and user-friendly. The 2.4GHz signal technology ensures strong, uninterrupted transmission, even through walls. The wireless fence mode covers a radius from 50ft to 990ft, providing plenty of space for your dog. If your dog crosses the boundary, the collar emits a warning tone followed by vibration and a low-voltage shock to guide them back. The system supports up to 3 dogs and is waterproof, ensuring durability in all conditions.
