heatworms in pup?

If a bred female is positvie with Heart worms ,well her pups be born with the micro? that turn into a hearworm

Nope. The heartworm has a life cycle that must include a stage/cycle within the carrier, specifically the mosquito. In other words, the dog must be bitten by a mosquito carrying the parasite; the parasite must actually be transmitted into the blood stream; and the larval stage must then move into the heart tissue to develop into the worms, all this taking up to several months to occur. The pups must receive the parasite from the mosquito -- the infection is not transmissable *directly* from one dog to another.
