Advantix Flea and Tick Medicine Review

I tried out K9 Advantix because it was less expensive than Frontline Plus and was advertised to repel more insects. As far as efficacy was concerned, it was comparable to frontline. It may have repelled mosquitoes and biting flies. I don't know. I didn't notice a big difference. The dog I tried it out on was a Brittany with thick fur. The applicator is dark, so you can't see how much is left to apply. I had to keep shaking it, and the dog got antsy. He also had to remain standing, not sitting according to the directions, so that added to the challenge. It was hard enough keeping his fur spread open to the skin and shaking the applicator, now I've got to keep getting him to stand up again. Even though the dog had thick fur with an undercoat and the product was applied to the skin, his fur became visibly oily. You could basically see it spread on his body. I did not care for it at all.
