Review on Flittor Dog Training Collar: Waterproof Shock Collar with Remote for Small, Medium, Large Dogs - 2 Receiver Rechargeable, Beep, Vibration, Shock Modes by Dora Macias

I'm so glad I ordered this. I have 2 taxis One is 1 year old, the other is 11 years old, he is deaf. The puppy is still learning not to bark at dogs or people on walks, but the other one? Well, she just loves to bark. I've been using it for 2 days and I love it. I can beep or vibrate both collars at the same time (he's in shock which I won't do) or put a collar on to correct the dog. Another great feature is the lock mode so you can't accidentally shock your dog when you put it in your bag. On our second walk, the girls fumbled in vain. love this product!
