I thought of that, but now that I've read the entire bottle it only says it treats round worm, and I'm pretty sure these ones are tape worms, although I really don't have a clue. It's called piperazine solution. I'm looking into getting some diatomaceous earth and might give that a go. I'm just hoping that if I clear out the worms his health will improve dramatically. It would have to wouldn't it?? Finding 6 in the kiddie pool over 2 days would that indicate a fair infestation, considering that he isn't doing all his poops in the pool... or is it normal? As far as having worms goes I mean, like a regular amount?
