Parasite protection is most effective when it’s proactive—not reactive. The best time to start using Advantage Multi is before your dog becomes vulnerable.
Begin use at 7 weeks of age, if your dog is at least 88.1 lbs
Use year-round to protect from heartworms, which are transmitted by mosquitoes—even indoors
Monthly application ensures continuous, cumulative protection
⏰ Pro Tip: Set calendar reminders or enroll in auto-ship to avoid missing a dose, which can leave your dog exposed to serious health risks like heartworm disease.
