I use frontline , Shayna is the only one that act like your boy, but only last few minutes and she is fine, hubby think is the high amount of alcohol on it, we have use other products, like advantage and the other one forgot the name
and doesn't seems to bother them that much, I use it because we are out a lot in meetups, walking, etc and none of my girls never had a flea well that I have seen it, only Phoebe had a thick couple of times one in her ears and the other time in her neck but that is it, thank God they have their Lyme vaccine and the tick was just regular thicks is what the vet said
not the lyme carriers, do what is has work for you
