Easy treatment

JessicaM March 11, 2026

[This review was collected as part of a promotion.] Now that the weather is getting warmer and we’re going on walks and exploring, my dog needed this! I’m so worried about ticks and fleas, and this treatment is perfect because you can apply on their coat. So far, no ticks or fleas on him! I love that he’s protected and happy!

Great protection for your dogs

RonaldJ March 15, 2026

[This review was collected as part of a promotion.] My first time using K9 Advantix II was about 10 yrs ago. I got them from a vet sample and couldn’t believe how effective they were. These were bigger dogs, but I see it works just as well in small dogs. Within a day, you’ll notice a difference. Not only does it kill ticks, fleas and mosquitos, but it keeps them away. One monthly dose is it. After applying, you’ll see a noticeable line where you applied it but don’t worry. Dirt won’t stick to it, and you don’t notice it long

Helpful and quick to use

GraceS March 17, 2026

[This review was collected as part of a promotion.] So far after 3 days there have been no negative side effects from the dose! It is very very small and kept in a tiny container. It makes it easier to distribute onto my dog and get all the spots that i need. The instructions are very clear and helpful. Easy to follow and get complete coverage for my dog since she loves going outside all day. Its easy to open with a top stab thing on the lid. Throw away all together in the trash. Definitely keep away from water and kids and cats! Worked well for my dog very pleased with the product!

Can be budget friendly and easy application for th

TamaraW April 29, 2026

[This review was collected as part of a promotion.] This K9 Advantix 2 is for a small dog weighing between 4-10 pounds. I dose is good for 30 days. Easy application for both the dog and its owner. At the nape of the neck you want to depart the hair opposite ways making a straight line and that’s wear you apply the medicine. For short haired dogs you can just use the tip of the application and go straight down in a line. I have used this technique many times any time I was in a pinch, but I always prefer the pill. This is a good alternative though.
