Dog No Bark Collars with Vibration and Rechargeable Anti Barking Device for All Dogs

Although my dog has trained very well in every other way, he would not stop 'screaming' with excitement in the car (very off-putting when driving!) and it worked within two days. I still put the collar on and he knows that I can buzz him if he starts, but so far not a sound. Excellent product for this type of training.
