Ah okay, I think I see your point. Sometimes I will just need a wormer as opposed to both, or there’ll be times that I need to worm and fluke but a triclabendazole based product would be preferable. So (stupid question alert...) if I do them all with the fluke treatment, can I then do the wormer at the same time??
Also, is the point of switching active ingredients to try and limit resistance? I’ve read about the different colours and varying degrees of resistance but not fully sure what it means.
