K9 Advantix II Small Dog

This is a great product, My dogs have used this for many years & works! No real need for heart worm meds, since this repels mosquitoes. Very good value. My dogs are outside often & no ticks or fleas!

This is the perfect flea and tick medication for my little Chihuahua. Works so well.

Works very well, excellent price

K9 Advantix does work. I’ve used it for two summers now. My only disappointment is that the product doesn’t prevent or stop new fleas from attaching to your pet. It will get rid of fleas once they’ve attached, but won’t stop fleas from attaching. It would be nice if this product could work as a preventative.

I have been using this since I got my dog. So far no ticks or fleas. She does not really go anywhere except for on a walk each day, so not sure if she has even been around fleas or ticks, but I keep giving this to her every month just to make sure.

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.

Works good . No irritation , no hair loss worked great .

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. :(
