We got a new puppy yesterday. I've never had a puppy this young before, she's only 7 weeks old today. She's a purebred dachshund, so she's very tiny. And boy is she hard at night!!! Does anyone have any tips or tricks to help her acclimate to sleeping without being cuddled up with her siblings? We try to let her cry herself to sleep because I read that's the best way to break the crying habit. But it's hard!!
