ok i have a corgy mix and she weighs about 15lbs. she got locked up with a male chihuahua that weighs 6lbs. i was wondering if she might be pregnant and not showing yet because he was so much smaller than her. the mated on dec. 20 or dec. 21. i need someone to help me out. i want to make sure that i am home when she has pups just incase something happens. ( i need to know if she is preg. 1st.)

I would take her to the vet they can check if she's pregnant for you and help you out with advise for her pregnancy. Good Luck would be interesting to see what the pups look like post us some photos if she is

Why was your girl allowed with a male dog whilst in season?

You need to get her to the vets to be checked over.
