My neighbors Chihuahua only had one pup and it died. The mommy seems sooo bummed...

My neighbors two yr old Chihuahua had her first litter this last Thurs. night when all were sleeping. By the time the family was able to help her, her only pup, born breech, had it's head stuck and died. Unfortunately it was her only pup and being only three days ago, she is having a horrible time adjusting without her baby. Some of her behaviors are: Super Clingy to owners, ears down and eyes looking sad-doesn't really even perk up to sweet talk, no tail wagging-it's tucked and it's staying there, and not eating real well. I can tell she likes to be held but keeps VERY still. Her teats are still very swollen as she has nothing to nurse. They've tried little beanie babies but she didn't like them. Thanks for any help and/or advice. P.S. She doesn't have any bad smells coming off of her, so I don't THINK she has an infection, but anything is possible. One strange thing I noted though is that I didn't see that she was still bleeding...it's only been three days.  Is this normal? thanks again Miss Shawnee
