2 in 1 Dog Training Collar Automatic Anti Bark Control with Remote Rechargeable and Waterproof for 3 dogs

We have a Husky Shepard Rotwiller Mix. He would bark and wine at every little noise. It was even worse if someone knocked on the door or came in the house, Now it is alot better. He is still a puppy so he is learning. It seems to be working well.
