My yorkie is constantly getting up at 4 am and starts barking. He is 6 months. He wants us to get up. I have given him toys, a stuffed animal and have even tried to tell him no barking and praised him when he stops but he continues to get up. We even got another dog so he would have company. The other dog doesn't bark just stares at him. The other dog is 4 months. I have seen collars but I don't want to shock him. I want to teach him and reward him. Please provide suggestions.
