K9 Advantix II vs Advantage II

Keep yourself and your pets healthy by selecting the flea and/or tick treatment that best meets the needs of everyone in the household. Two of the best-loved products are K9 Advantix II and Advantage II. While both products are top-quality, reliable, and safe, there are some differences that could help you choose between the two. The information and table we’ve assembled here are designed to help you make the best decision for your dog.

How does K9 Advantix II differ from Advantage II?

These two impressively effective medications are similar in a number of ways. For starters. They are both topical treatments that work to kill adult fleas, flea eggs, and larvae. They also both treat lice. They are both made by Bayer Animal Health, they are both formulated to be administered monthly, and neither product requires a prescription. They can both be used on puppies over the age of 7 weeks (K9 Advantix should only be used on puppies and dogs over 4 pounds). Neither product should be used on a pregnant, breeding, or lactating dog without veterinary consent.

Advantage II is available in a feline formula as well, while K9 Advantix II is made only for dogs. Advantage II contains Pyriproxyfen and Imidacloprid. K9 Advantix II combines the active ingredients of Pyriproxyfen, Imidacloprid, and Permethrin.

The most notable differences are the additional parasites each product is effective against. K9 Advantix II offers added protection, working to kill and repel ticks and mosquitoes, and it repels biting flies.

Final thoughts on K9 Advantix II vs. Advantage II

With the many benefits of each incredible product, you can’t go wrong when you choose either of these effective products. However, there are a few factors to consider when making your decision.

If you intend to treat a cat, you should opt for the feline Advantage II product. If your dog would benefit more from protection against mosquitoes, ticks, and biting flies, K9 Advantix II is an ideal option.
