When I first got Max I was reading on the internet about different types of flea and tick preventatives and there were so many bad things about not only boi-spot, but SO MANY others (K-9 advantix, hartz, etc.) I know a lot of people who use those and their dogs don't have reactions but I'm so afraid to put ANYTHING on my dogs, so they go unprotected
I hope your babies get well very soon.
