Review on PetSpy P620B: Waterproof Dual Dog Training Shock Collar with Vibration, Electric Shock, Beep - Remote Trainer for 2 Dogs, 10-140 lbs by Lakeisha Butler

We ordered this because we urgently needed help with our dogs. Have two medium sized dogs that have been fighting for attention causing literal fights. We used vibrations and sounds, as soon as we saw her behavior change, to avoid a fight we had to shock a few times at a low level and it worked perfectly. It's quiet again in our house. Now the noise is enough to get their attention and stop bad behavior. My only regret is not having ordered it sooner. The remote control is easy to switch from one collar to another. Would recommend to anyone who needs help studying.
