"K9 Advantix II"
Works great for fleas, better than anything else as there is no competition for mosquito repellant, we live in Florida we need more of that, did not kill Lice as it states it does so I had to order more stuff and this is expensive. No vetinarian prescription needed. Great flea control and good mosquito repellant wish there were more for repelling mosquitos especially to prevent Heart worms that part of this is awesom but i dont think the mosquito repellant last longer than 2 weeks. Great at abolishing fleas in every lifecycle. Hreat OTC
LOVE IT WORKS BEST FOR DOGS IN THE WOODS ALOT
"K9 Advantix ll"
Safe and works great!
I live in s.w. florida, which is mosquito headquarters, & this stuff really works on ticks, fleas & DREADED MOSQUITOS. effective, yes very. expensive, yes, very, but Jeffers gives the added option of a 2 count when one is on a very tight budget but still wants the best for their babies. YAY Jeffers.
Very happy with the K9 Advantix.
"Advantix II - I have big dogs"
i have big rotty's, I have used this advantix II for years, but it no longer works. In 2 to 3 weeks they are scratching again. No swimming pool now , just a large tank they swim almost dailey, before it did not matter , nut now it does not last
Applied this to my dog as directed 10 days ago and she is still miserable. She is not getting any flea relief at all and she is on the low end of this weight category. Granted, we did not have any winter this year and the fleas are bad but she should still get relief with this product. I would rate this a 3 at best.
"works great here in the South"
...where we have fleas all year round. I have 5 dogs ranging in weight from 4.9 lbs - 135 lbs. Plus various dogs coming in to show. No fleas, no ticks, no coat issues and I just can't have coat problems on a top ranked show dog!!!
"It does it all"
I like having a pest control that does it all. Makes it easier to remember to do their treatments once a month. With the other ones I have to buy another control for heartworm.
"k9 advantix II"
I reviewed it before, and I can say IT REALLY WORKS!! I hope it continues to work well. JE T Jr Laurens, SC..
"K9 Advantix II"
I've used this stuff since I discovered it several years ago. It does the job well, plus it covers one more pest most others don't. Mosquito's. The price might seem high but that more than makes up for the fact I don't have to buy the extra repellent.. I use both the small dog one and the large one, and I've never had a problem with it.
"Not all that good"
Extremely expensive product. One would expect it to work fantastically for what it costs! At $80 I had expected much more! I have five dogs. I will be looking for a better brand which works.
"k9 advantix II"
(I used Frontline for years with great success, however this past year it has not worked..tiny fleas, cat fleas? on my dogs. BUT this K9 ADVANTIX II is working GREAT!! I suppose the fleas have become immune to the Frontline and the others I have tried. Expensive, compared to others BUT WORTH IT!! James PS: How are things "Down Home" have kin-folks down there.
"Just once a month"
All I have to do is remember my Advantix II once a month and it protects my dogs against everything. All the pests including mosquito's. How easy is that???
