The best wormer to use at that point is going to be a fenbendazole. Its used in your safe guard horse wormer its the only thing you can give her to kill all worms that puppies are born with. I recommend giving this to the her in two week intervals after the puppies are born. The puppies will get it thru her milk. And using the Nemex2 in 2 week intervals for the puppies. If you have any questions on dosing just ##*%* me a pm.
