K9 Advantix II Small Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention | Dogs 4-10 lbs. | 6-Mo Supply

Doesn’t work at all. I am surprised that I see reviews here where people say that it works. I got two boxes at home and have 7 pound dog. I gave her a dose for fleas. Two days later, she still had fleas. So I gave her a second dose, hoping that the product is just weak. And two days later after the second dose, she still had fleas. So I used another product that I have and that one worked. Several months later, I tried again. At that time, I was dog sitting my friend’s dog and gave a dose to both dogs. Didn’t work on either one of them so I doubled it up again and it still didn’t work. So I gave both dogs the other product that I had and the fleas were gone in couple hours again. I don’t understand the reviews that I see here when people say it works. Did they get different product than I did? Was there some manufacturing mistake? I have two boxes at home and each one I bought at a different period. I don’t understand why it doesn’t work. And certainly will not buy this thing again.

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.

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!

I have purchased this multiple times for my dog. It works exceptionally. I definitely recommend it.

I have 3 dogs so keeping them flee-free can be expensive. (Over $150 a month with some brands.) I think I've tried nearly all the various flea treatments; dips, shampoos, organic non-toxic, aromatherapy oils, powders, etc. This K9 Advantix II works better than anything else I've tried. Within 24 hours of first application, no fleas! And no fleas for almost exactly 30 days. It seems to have a timer on it. I lost track of the date and didn't apply 2nd dose until I found a flea, checked the calendar and it was 33 days since 1st treatment. After 3 months of on-time dosage, no fleas on the dogs, no fleas in the house, and they don't bring any in from outside so the repellant is also working. I was reluctant to use what is essentially poison on my small dogs, but as nothing else was working and we were all miserable, I had no choice but to try this. I am happy to say they haven't shown any ill affects at all from 3 months of treatment and we are all much more comfortable.
