Review: This is the perfect flea and tick medication for my little Chihuahua. Works so well.
Review: Can’t say positive or negative if it’s effective on ticks. Seems to do a decent job against mosquitoes. However that’s where the positives end. This ATTRACTS FLEAS. That I’m absolutely convinced of. I’ve had multiple flea issues with my dog using this. So either the fleas in Eastern NC are immune to this or this stuff is counterfeit.

## Questions & Answers

**Q: can k9 be used on puppies 8 weeks old  she  keeps biting her side  like something is there**
A: I would try giving the puppy a bath with Dawn liquid soap and talk to you local vet about giving this to your new puppy

**Q: Do u have one for Poodles 21 23 lbs.**
A: Use Frontline or Advantage. Advantix does not work as well.

**Q: Can anyone in florida give me your opinion on it’s effectiveness? i’m told that the fleas in fl are developing a resistance to some treatments.**
A: I live in the Tampa Bay area in Florida and used this on my chihuahua for over 3 years and it has been very effective.  I do not give him heart worm treatment since it repels and kills mosquitos as well and every time the vet has done his heart worm test, it has been negative.  Therefore, I highly recommend this product, not only for fleas, which he has never had but for mosquitoes as well.

**Q: Delivery on6-28?**
A: Hi. Unfortunately, we’re not able to answer this question. We recommend you contact the seller for more information.

### ⭐⭐⭐ Review
*by F***O on 28 September 2022*

We followed the instructions to a T. It's not our first time with K9 Advantix, but it was the first in a long time, as we have no problems with fleas and ticks in our area,but wanted to make sure o ur pups were protected against them while out in the wilderness for a camping trip. About 4 days after the application, our 6 yro Yorkie became extremely lethargic, stopped eating, drinking, and had several bouts of diarrhea. My husband noticed a rash on his back, from the base of the neck all the way to the middle of the tail. Thinking it to be an episode of gastroenteritis, we switched him to a bland diet peppered with probiotics, administered an anti-hemetic and kept an eye on his fluid intake. No changes. In several trips to the vet, we had his blood, urine and stools tested - no signs of g.i., heart or kidney issues. X-Rays and ultrasound showed no abnormalities. The doctor was at her wits' end, as we tried and tested everything we could - when we mentioned the flea/tick treatment, she showed concern and advised us to be aware of the adverse reactions such treatments might bear, especially on small breeds. This situation went on for almost a month until he started showing improvement. I'm cannot say I'm 100% sure K9 Advantix was the root cause of my dog's sickness, but considering the amount of tests ran and the fact it was the only "change" in his routine over the course of that month, I can't rule it out either. Just be careful and aware of the possibility of side-effects. We'll not be using it anymore, and with that we cannot recommend it again. :(
