LOL - Welcome to the bully life. Tyson is 9yrs old, and I lose sleep constantly if he doesn't feel well - which is currently with some stomach issues, it never ends. We use heartguard & Frontline and only during the hot summer months, due to bugs, and mosquitos at night. During the winter, nothing. He isn't at daycares or parks around other dogs so our concern with fleas isn't high. I'd say try one, and see how he does with it. Just buy the small pack to start.
