The effect of praziquantel on Echinococcus granulosus, Taenia hydatigena and Taenia ovis infections in dogs.

The effect of praziquantel on Echinococcus granulosus, Taenia hydatigena and T ovis was investigated in a trial involving 360 dogs. The drug was found to be highly toxic to tapeworms. Few dogs remained infected after a single treatment within the range of dose rates tested (0-31 mg/kg to 10-0 mg/kg body weight). No toxicity to dogs was observed.
