I feel your Pain, I have had baby Keegan for about a month. I would strongly advise crate training. I crated Shaianne, and Keegan gets crated when I am at work and when we are sleeping. It took her about 2 weeks to finally settle down at night.
I can certainly understand why Tess doesn't want her poor little feet to touch the cold hard ground, I don't blame her a bit!
But consistence is the key. Keegan is slowly getting trained. The vet told me today, that when I get home from work to not make such a big deal over Keegan, to practically ignore her other than taking her outside, and that will reduce the chances of her becoming a submissive peer, which is what we don't want!
Very hard to break, my sister's dog is a submissive peer and he is over 2 years old.
I know how you feel, I felt I wasn't good enough for a puppy either after the first couple of nights, but it does get better.
