the puppies might be alright, but i think having the puppies be born early might do a little damage to the mother chihuahua. you can be pregnet for a few months then have the babies when they are ready. i dont know mutch about dogs.
A puppyâ??s looks will depend on their breed. Some newborn puppies will be born bigger than others; for example a Chihuahua will be very small, while a Mastiff is larger. Puppies are born with very little fur and their eyes and ears closed.
