Answer
ok, first of all OTC dewormers are a sad story.  

Go to your vet and ask for the pregnant dog to be dewormed properly-because she needs to. There is also a product called Revolution that I do believe is safe in pregnant animals.

NEVER give meds to a pregnant animal without consulting your vet. :)
