Dog Training Collar with Wireless Remote Rechargeable 300M

I saw a similar dog training device from a professional trainer. So I also bought one. With the multiple modes available, it has helped in reducing the frequency of its barking. My dog really responds well to the vibration then anything else. I didn't have to shock her. Very easy to set up and use. A good value worth trying. Well made and less than half the price of the one the trainer offered. Be sure to test it on yourself before using it on the dog. It came on at 100. Gives quite a shock. Recommended turned it down to below 35.
