I'm too hesitant to try any of the chemical drops with the bad reactions I've seen.
Well, actually my vet recommends against topical for my basenji kids. They said that they have plenty of dogs in their practice that got Lyme while on topical. The best line of defense is to look my kids over after they have been outside. I too have heard too many horror stories and I don't want pesticides on my bedding or furniture. Granted I have it somewhat easier as my kids are 2 red & whites and one red brindle…black, dark brindle or tri would be harder to find a tick on.
