**7. Treatment of infected dogs**

Praziquantel is the only drug without significant undesirable effects known to be effective against *E. granulosus*. With a dose of 5 mg/kg, it can indeed achieve 100% efficacy [30, 31]. Because of its very broad therapeutic index, praziquantel is particularly suitable for cystic echinococcosis control programs [32]. Indeed, after its introduction in 1977, it was widely used in the majority of programs that undertook the control of the disease.
