Hi, my friend's Shih-Tzu had puppies about 9 days ago. Today she discovered she has tapeworms. Ugh. And because she is nursing, she can't have tapeworm meds. What can my friend do to control/get rid of the worms? Should she wean the puppies as early as possible so the dog can have the droncit? Or bottle feed the pups and give the dog Droncit? Anybody know?
