ivermec is no use as a wormer , ivermec will not kill TAPEWORM it will treat pin worms, roundworm and lungworm , and as someone said if you don t get the dose right it will affect your dogs sight and sense of balance etc MUCH BETTER OF USING -- DRONTAL , PRAZIVET , PRAZITAL, MILBERMAX , CESTEM , TOSAN 500 EVEN BOB MARTINS
IVERMEC is good for mange and other skin/mite problems but as a wormer its NO theres better cheaper stuff out there
