Hi, New puppy 10 weeks old, and brand new puppy parents. She has a crate and is happy to sleep in it -she goes in and out on her own when she wants to go to bed. The crate is in a bedroom in a penned area - this is often left open as I let her around the house unless I need her tucked away. At night I let her out to pee before I go to bed (around 12), then put her in the penned in area..but then she has a complete mad hour. ..shes chewing madly on anything, crying, whining, howling...generally going crazy, just when I really need to go to bed. What am I doing wrong ?
