*Features*:

*Automatic Dog Training*:The transmitter emits a harmless radio signal in a radius around itself and the signal is detected by the collar. If your dog walks out of the signal boundary; the receiver will send sound warning first and then emit safe static stimulation until the dog goes back into the signal boundary. In this way; your pet will gradually recognize the existence of fence boundaries and learn to stop at the warning signal.
*Adjustable Boundary Range & Shock Level*:You can customize the 4-level adjustable radius of the boundary from 131ft to 722ft; suitable for both indoor and outdoor usage. With 0-8 level adjustable shock intensity; you can adjust the stimulation level whenever needed.
*Adjustable Neck Circumference*:With an adjustable neck circumference of 5.5in-23.6in; it’s suitable for small; medium; and large dogs weighing 4lbs+.
*IP67 Waterproof Collar*:The IP67 waterproof receiver can work normally when your dog swims or runs in the rain. Make sure that the charging port is well-sealed before the dog enters water.
*USB Rechargeable*:This USB rechargeable collar can stand by for up to 10days after being fully charged for 4hrs. No need to recharge it frequently.
