Is she going to ever have puppies?

Got a problem and I am not very sure how to go about answering it! Well my boyfriend and I have a 4 year old dalmation....she went in heat and we introduced her to a male dalmation it has been 2 months almost and she is plumped and finally getting milk but sometimes she is plumped and others she look normal? Is it false pregnacy or what? Please Help and too....can you give a preg. dog wormer?
