Same-day results matter when fleas are already active — Advantage II starts killing adult fleas within 12 hours of application, rather than making you wait days to see any change. It also targets flea larvae and eggs, which is what actually stops an infestation from restarting rather than just knocking back what's visible right now.
One application keeps working for a full 30 days, and this pack covers 6 months of treatments, specifically sized for small dogs weighing 3-10 lbs and at least 7 weeks old. It's vet-recommended, available without a prescription, and works for both indoor and outdoor dogs regardless of how much time they spend outside.
The formula is fragrance-free and becomes waterproof 24 hours after application, so baths or rain after that window won't compromise the protection. Application is topical and simple — no oral dosing, no complicated steps.
Active Ingredients: Imidacloprid, Pyriproxyfen
For dogs 7 weeks and older, weighing 3-10 lbs. As with any flea treatment, consult your veterinarian before use if your dog has a known sensitivity or existing health condition.
