As Bryant said, you still have a happy healthy tape worm.
Go to your feed store and get you a tube of Zimectrin Gold. Give them a clot about as big as a M&M and your problems will be solved. There was a thread not long ago in the dog doctor section about this.
It runs about $16 to $18 bucks for a tube around here and it will do several dogs. You will end up spending more than that messing with cheap wormers, expellers and home remidies and still will likely have worms and end up having to buy it anyways.
