Tell you what....show those 4 studies to DVM's when they tell you they're seeing lack of efficacy with Frontline Plus and dogs still have fleas. Real life trumps any study. The only thing that is needed now is the fipronil. DVM's never see it fail on ticks.
Also, lab fleas not same as field fleas. Why do companies/ labs do this? Marketing ploy?
