There were dogs dying from one of the chewables. Not sure what the brand was.
I gave up on flea and tick prevention. I figure when I see a flea, I am going to hit all the dogs with both barrels, flea bath, and then the next day hit them with advantage or revolution, and maybe the next month repeat. I decided this about four years ago. My dogs have not had any prevention in that time. I am hoping by eliminating pesticides as a prevention, I may prevent disease from the pesticides. But if they are being attacked, I will get involved.
My problem is black flies and I and the dogs have been tormented by the nasty monsters. Occasionally I will use fly spray, or swat, both of which helps.
