The Equimax horse wormer is 14.03% Praziquantel and 1.87% Ivomec which at a gram would be the correct dosage of 140mg for my dogs as most of them are the same size. My question is at the same amount the dosage for Ivomec is 18.7mg, is that too much Ivomec? I don't want to overdose my dogs. If it is then I'll go another route and use them separately.
