It's kind of strange.. only one of the dogs is picking up ticks. I haven't found any on any of the other dogs. None of them have fleas, I haven't seen a single flea all year on anyone. Our vet just started carrying this collar this year, and I was just curious if it would be safer and more effective than getting Frontline Plus. Does it stink like a flea collar? I can't stand that smell. I am mainly wondering about this because the Frontline Plus never seemed all that effective against ticks in the past.
