This wireless electric dog fence system creates a safe circular boundary around your home or garden using radio waves instead of a physical fence. The transmitter emits a harmless radio signal that is detected by the waterproof collar receiver. When your dog approaches the boundary, the collar delivers three warning beeps followed by safe static stimulation to gently guide them back into the designated area. The system features adjustable boundary ranges from 131 feet up to 722 feet and eight adjustable stimulation levels to suit dogs of all sizes from small to large. The rechargeable lithium batteries in both the transmitter and receiver provide up to 10 days of operation on a single 4-hour charge. The collar is adjustable from 5.5 to 23.6 inches to fit comfortably on small, medium, and large dogs. The IP67 waterproof-rated receiver ensures reliable performance in various weather conditions. This containment system supports up to three receiver collars, making it ideal for multi-dog households. This training system helps pets learn to stay within established boundaries naturally and keeps your furniture and belongings protected. The transmitter operates on standard 100-240V power and includes a USB charging cable. The compact and lightweight design makes installation simple without the need for buried wires or extensive setup.
