I’ve been using K9 Advantix II for years, and it’s truly a lifesaver for my Golden Retriever! Even with his long, thick fur, this product keeps him completely free of fleas, ticks, and mosquitoes during peak season. It works wonders, and I always keep some on hand for those unexpected emergencies.

Advantix II is by far the most effective flea and tick treatment I’ve used for my dog, especially against those pesky mosquitoes that are a constant threat here. While some topicals can be a bit strong, I’ve found that spreading the application out makes all the difference for her sensitive skin. It’s a fantastic product that truly delivers on its promise of protection.
Patricia Collins
Before K9 Advantix II, my dog was constantly scratching and just miserable. I’m so thrilled that after trying numerous products, this one finally brought her relief within 24 hours! It’s incredibly easy to apply and gives me immense peace of mind knowing she’s protected from so many different pests. This product has truly improved her comfort and overall happiness.
