Hi neighbors! I have an unopened box of 3 doses of Frontline Plus for dogs (23-44lbs.). I can't find an expiration date on it, but I've had it less than a year. In full disclosure, my dog contracted Lyme disease while on Frontline and this is why I switched to another tick/flea preventative and have this unopened box. But if anyone still uses Frontline, I'm happy to pass it on for free. I also have a bag of various kinds of opened but still yummy dog treats that I would hate to throw away. After contracting Lyme disease, my dog is now on a low protein diet, so I'm getting rid of all of the high protein treats I have. Please let me know if you're interested!
