Manan Chawla
Bravecto and Advantage II are two of the most trusted flea treatments for pets. Both protect against fleas, but they differ in how they’re applied, how long they last, and which parasites they target.
Once you know these differences, you can confidently choose the safest option for your pet.
This guide breaks down how Bravecto and Advantage II compare across their formulations for both dogs and cats so you can make the best decision for your furry companion.
1. Understanding the Products
Bravecto (by Merck Animal Health)
Bravecto is known for its long-lasting flea and tick treatment for dogs and cats. It uses the Bravecto active ingredient, Fluralaner, which kills fleas and ticks within 2 hours and continues working for up to 12 weeks. For some tick species (lone star ticks, American dog tick), the effective duration is shorter, often 8 weeks.
The brand offers a range of products for both species, including:
-
Bravecto Chews for Dogs – oral tablets that provide 12-week protection and are among the best flea and tick treatments for dogs.
-
Bravecto Topical for Dogs and Cats – easy-to-apply topical solution lasting up to 12 weeks.
-
Bravecto Plus for Cats – adds protection against roundworms, hookworms, and heartworm (2-month duration).
All Bravecto products are prescription-only and designed for convenience with fewer doses and long-lasting protection.
Advantage II (by Elanco Animal Health)
Advantage II is a monthly topical flea and tick treatment for cats and dogs that kills fleas across all life stages. It uses two active ingredients, Imidacloprid and Pyriproxyfen, which work together to eliminate current infestations and prevent new ones from forming.
Here’s what the line includes:
-
Advantage II for Dogs – kills fleas through contact, without requiring a bite, and also treats chewing lice.
-
Advantage II for Cats – kills adult fleas, eggs, and larvae on contact and helps prevent re-infestations.
-
Advantage II for Kittens – gentle formula suitable for young cats above 8 weeks old.
Advantage II is available over the counter and provides fast-acting, easy monthly protection that’s safe for pets and families. Advantage II targets fleas (adults, eggs, larvae) and lice, but has no tick-killing effect.
