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! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable protection for my girl! *by on Reviewed in the United States May 13, 2026* ​Finding an effective flea treatment for a large dog can be a challenge, but Advantage II has always been my go-to. This 4-month supply for dogs 55+ lbs is perfect for keeping my dog protected throughout the season.
