My 5 month old has tapeworm and we just used the over the counter med. Worm X plus for small dogs and puppies, I had to give her one pill that she took with no problem they said in about a week the tapeworm should just disapear. If not back to the vet for Daisy. Which is funny becuase she developed the tapeworm just 1 week after getting her deworming from the vet!(kinda odd) I have two cats but they don't have fleas not sure where she got it from. If anyone has ever had this expirence please share and let me know what worked for you.. Thanks
