Is my chihuahua pregnant?

So my chihuahua is only 9 months old and just went into her first heat cycle apox 2 weeks ago, and only bleed for 7 days. We watched her as closely as we could before, waiting for her first cycle, and we never thought that she could of gotten pregnant...

before the first heat until today. I noticed about a week after she had completely stopped bleeding (while she was bleeding we kept her away from any male dog and she has yet to be around another male dog) and now ALL of her nipples are VERY swollen and are hanging like she is producing milk. Could she have gotten pregnant before her first heat cycle?

Is her stoamch really hard because my dog is the saame way and I need 2 know if my dog I preggo 2

Her nipples would not be hard yet. She will not show signs of being pregnant until the last 3 to 4 weeks. There are 63 days in a dogs from the time she ties with a male until she will delivery her puppies.

my female had the same problem after she was in heat she had pregnancy type symtoms and she was having a false pregnancy I advise you to make sure by going to the vets and if the false pregnancys carry on you should get her spayed

Possible. My friends dog/chihuahua got pregnant at 8 months and had 4 puppies. This was her first heat cycle. A dog wont let another dog mate with her if shes not in heat. It is possible for her to be pregnant. If she is or not only time ( 64 days from the time of conception) will tell.
