Is there a medication that takes care of all worms including tape worm? I have had to recently worm my dogs for roundworm, hookworm and tapeworm! I think I should do the chickens too, just to be safe. Also, is there something I need to do in their run? Can they get the worms from the ground? Is there a link someone can direct me to for info on this? Thanks in advance! The chickens and dogs do not mix, but their run is in a place where the dogs used to play.
