She may not be feeling well. Tummy ache maybe? Sometime they just want a cuddle. They are used to body warmth from litter mates and Mom. Today Mya was crying and I went through the list, walked her, fed her, gave her water, played ball with her, checked to make sure she was ok, no sticks stuck in her fur ......finally I just held her...I was on the internet and took a 15 min cuddle break. It was good for both of us. Also make sure you don't have music up too loud ......booming ....they have very good hearing and I remind myself to keep the music down when she is in the car with me. I would check your baby over.....make sure no cuts or anything then try the cuddle. Remember puppies are well........puppies
