Worked fast and gave my dog immediate relief
My Shih Tzu is part of the family, so seeing him constantly scratching and feeling uncomfortable really worried me. After spending some time outdoors, he picked up fleas and started scratching so much that his skin became irritated.A friend recommended K9 Advantix II, and I'm so glad I tried it. I noticed a difference the very same day. He stopped scratching, the fleas were gone, and he was finally comfortable again.It's been about a month since I applied it, and even after a couple of baths, he hasn't had any flea problems. The price may seem a little high, but when it comes to your pet's comfort and health, it's absolutely worth it.For reference, my dog is a Shih Tzu weighing around 9–10 pounds, and this product worked exactly as I hoped. I would definitely recommend it to anyone looking for fast and effective flea protection.

Original is Best
This product worked, but the added medication for flea eggs caused a problem. My little dog was jumping out of her skin for 2 days. It caused uncontrollable itching both times I used it. I switched to the original K9 Advantix and voila… no problems! Sometimes the original doesn’t need messing with.
