Highlited in yellow. **Q: Is it ok to put advantix and advantage ii simultaneously on a larger dog? advantix for l and advantage ii for sm. that amount needed for bigger dog.** A: Each box will have a different expiration date on it. We had a box for at least a year, it still worked on the dog. **Q: What are ingredients?** A: Strange that they leave this part out of the description as it is rather important. I have used this product on several dogs for years and purchased here and the online pet pharmacy out of Canada (wife ordered and I forget the name) but never had a problem but just like humans, some dogs have different reactions than others to certain products/chemicals, so do be careful to follow directions and monitor a bit to make sure your pet is taking it as expected and not having any reactions. Since they don't list it, I would email them seller directly, and/or look on the manufacturer website for more info. **Q: what is the difference between Advantage 11 and Advantage?** A: Advantage II Is a better flea control and does not wash off as does Advantage. Advantage II is what you want! ## Frequently Bought Together - Advantage II Large Dog Vet-Recommended Flea Treatment & Prevention | Dogs 21-55 lbs. | 4-Month Supply - Advantage II Large Cat Vet-Recommended Flea Treatment & Prevention | Cats Over 9 lbs. | 6-Month Supply - Advantage II Medium Dog Vet-Recommended Flea Treatment & Prevention | Dogs 11-20 lbs. | 4-Month Supply --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/15078466-advantage-ii-large-dog-topical-flea-treatment-and-prevention-4ct](https://www.desertcart.hr/products/15078466-advantage-ii-large-dog-topical-flea-treatment-and-prevention-4ct) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-25*
