How long are female dogs pregnant for?

Question

Oh and is it noticeable right away?

About 2 weeks ago was when we noticed her belly area getting bigger and her **** got big also...and she is very aggresive.

Just trying to figure out how far along she is.

Answer 1

Approx. 63-65 days.

Answer 2

9 weeks, give or take a few days based on litter size.  

Answer 3

63 days, give or take a day.

Answer 4

they are pregnant for about 2 months. you should take her to the vet though because even though she may look pregnant she could be having a false pregnancy. most dogs do that after they have had puppies before. our dog has looked pregnant 4 separate times but was only truly pregnant once and she had 8 adorable little babies.  feel on her belly to see if its hard but you really should take her to the vet they can do an ultrasound and tell you more
