We use Frontline on Lucky our large dog and Advantix on Lucie the small one. Frontline for some reason made Lucie nervous and she could not rest. My son switched his dog over to one of the pills and within a week he almost became lame in one of his hind legs. The side effect of the pill was lameness in some dogs. So they switched him over to Seresto and now he is back in good shape.
Clearly, dogs react differently - both of my dogs acted like I had poured Drano on them, using topicals. Jimmy reacted so badly (physically and mentally) that I put him in the tub and washed the stuff off (can't remember which topical it was). I'm just grateful that we have plenty of options!
