The mother can pass the larva to the puppies, but they do not develop into adult worms..BUT the pups will be carriers and in that case it can be dangerous to start them on heartworm prevention..make sure they are tested before giving meds...
It would be much simpler to have the mother tested...if she is negative, then there is no worry..if she is positive, then there can be a problem.
