According to several vets I have spoken with and page 212 of KVpet catalogue, the only effective tape wormer for dipylidium is praziquantel. Panacur, is fenbendazole and will NOT kill tapeworms (dipylidium) that are acquired from fleas. It will however, kill tapeworms (taenia) acquired from eating rodents and rabbits. Panacur is effective on roundworms, hookworms and whipworms. Dave Coleman ROCKNOLL GERMAN SHEPHERDS ************** An Excellent Credit Score is 750. See Yours in Just 2 Easy Steps!
