Is My Dog Pregnant

Your dog may not show many obvious symptoms that she is pregnant during the first three weeks that she's become pregnant. Maybe she is more affectionate with you and a little hungrier.

If that doesn't tune you in, perhaps, when her nipples slightly enlarge, you'll get 'it'. When a clear mucus vaginal discharge starts four to five weeks into pregnancy, you'd really have to be inattentive not to notice! Btw, the discharge continues until the dog gives birth.
