my pregnant chihuahua

Question
I want to know how long chihuahuas are pregnant for? She's about 57 days into her pregnancy but she's not very fat. Is that normal? Also, some of her nipples are not developing all the way. Will they all come out eventually? I'm just worried that she's not going to have enough for all her pups.

Answer
The average gestation period would be 63 days.  It is possible that her nipples may still develop or that not all of them will be functional, however usually there will be enough functional for the number of puppies born.  Size of litter varies, however giving her small size and lack of development it may be prudent to have you veterinarian take a peek at her if you are able before she gives birth.

Best of luck to you and the expectant mother.
