I have five puppies that are almost 5 weeks old. They have started running around and are beginning to come out of their cage. I leave the door open for mommy. They chase and terrify their father. He tries to smell them, but when they turn around, he jumps back. Then they run towards him and he races away and runs all over the room. It is so funny! Tonight they keep climbing out of bed and crying at the door. Finally, I've locked mom in to quiet them down. I think the next few weeks are going to be frantic!
