I dont think tpaeworms are really contagious but if you ingested a flea from the same carrier you may possibly get one. I think the care your referring to Barkingdog is for worms such as whipworms, hookworms etc. A tapeworm lives inside the body until it is fully mature and then the tail section breaks off and exits via the dogs stool.
If you google tapeworms and remedy's you will see some interesting homemade remedys. I would highly reccomend getting the problem dealt with at the vets. Many years ago my two cats got a tapeworm and the vet gave them both a needle to get rid of it and it killed the tapeworm. It did not come back. I am assuming that you have not siccessfully killed the tapeworm.
Good Luck and let us know how you make out.

He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
