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.

Best for my pet
This is the best flea treatment so far for my 5lb chihuahua. Just like humans every dog is different so it’s important to find what works best for your pet. My dog has epilepsy and a heart condition and has no irritation with this medication and it works immensely better than frontline. I think the fleas in my area are immune to frontline so that could be why it doesn’t work. Same for my sisters cats, frontline doesn’t work either. Advantage works the best for getting rid of fleas. I was told to use a different medication each month so last month I used frontline and my poor baby was bitten up. She might have had about 5 fleas on her but it still makes a difference and about 30 minutes after I put on advantage she’s feeling better. That month was horrible for baby. I’m glad we’re sticking to advantage now. But remember every dog is different and fleas in your area might also have immunity to certain formulas as well so it might take time to find the right flea prevention for you.
