I don't know.... actually didn't even know there was a craze! Tape worms are carried by fleas aren't they? -unless they have another 'host'... and horses don't get fleas.
Well worming for tape worms is sweeping this area:) and Yes, that was my understanding about tape worms, they come from fleas, and I've never noticed that any of my horses had fleas:)
But all the big horse worms, Zimectrin, etc, have come out with a wormer that cleans out tape worms. It's more expensive of course:). That's why I've been wondering. Last summer I had alot of people ask me if I had wormed for tape worms, and suddenly started seeing the horse wormers that took care of them and adverisements in magazines about them. That's why I thought it was a craze.
