Dog Shock Training Collar with Rechargeable Remote Controller (Shock/Vibration/Tone Modes, 400 Yard Range)

Place the collar around your dog and make sure they don't go too far with the accompanying remote control. Deter your dog from mis-behaving by transmitting mild shocks that do not cause pain but stops their naughty or aggressive behavior when out on a walk. Or if you prefer you can also use the vibration setting or even the tone settings which cause absolutely no shock to your pet but still will get the message across that your dog is misbehaving. This kit comes with two collars and two receivers, therefore if you have two dogs you can control both at the same time. The transmitter controller is small and light and fits in your pocket and will not be a burden to carry when out walking your dogs. And to top off everything, the remote control has a range of up to 400 yards in open air conditions so no matter where your pet is you can administer the needed correction if your dog misbehaves.
