The Day the Fleas Packed Their Bags
5 stars. The fleas showed up. They rented tiny imaginary apartments in my dog's fur. Just a quick drop in a few spots. Now the fleas are packing their bags and moving out. Zero stars from the fleas. Five stars from us.

Easy to Use and Vet-Recommended
I’ve been really happy with K9 Advantix II for my medium-sized dog. It’s easy to apply, and I like knowing it’s a product recommended by veterinarians for flea and tick protection. The application is quick and convenient, which makes keeping up with my dog’s routine much easier. So far, it’s been a great choice for us!

Works on fleas
This worked on fleas. Frontline didn’t work, advantix didn’t work. Advantix II was the only thing that killed the fleas.

Don’t use - harmful to animals
I used this on my senior dog and followed the instructions, but it made my dogs skin split open and become a “hot spot” and filled with puss. This required a ~$500 vet visit, including irrigation of the skin, antibiotics, ointment, etc. My poor dog . Horrible product, don’t be deceived by the reviews like I was. The photo attached doesn’t even show the split skin but just the hot spots. Also this is at the top of his back so it’s not like he had been chewing at it or anything because that would not have been possible.
