My puppy did the same thing. No crying the first night, and after that started crying at being left alone. I think he was in shock the first night, because the first couple of days he wasn't very active either. And after that, he warmed up to us and started running around and crying.
To train mine not to cry, when he was in his crate or playpen, I did not get him out until he stopped crying. Sometimes I had to wait around the corner for 15 minutes waiting for him to stop crying so I could let him out. That way, I was rewarding him for NOT crying. If you let them out when they cry, you are rewarding the crying. |
