Never fails!
April 12, 2018
I tried Advantix II on my boston terriers after trying another topical flea/tick prevention failed. I've also tried the 8 month collar. This product is by far my favorite! It has never failed to repel fleas, ticks and mosquitoes even after I've bathed the dogs! Recommend!!
ProsLasts through bathing
ConsCan feel sticky

Have tried many different kinds of flea treatments over the last 30 plus years and K9 Advantix II has been the best to insure my home is flea free. With so many dogs I can not afford to have any chance of fleas breading and this is the best which is also recommended by my vet to add to the to the quality of the product.

I live in Maine and we have tons of ticks but with K9 Advantix ll I never find even 1 on my dog, and not a flea either, great stuff.

Very Affordable

I find most flea killers are way out of my price range but not at Entirely Pets. This K9 Advantix II was very affordably priced.

K9 Advantix II is the ONLY product that has worked on my labs. No more Hot Spots as their hair grew back quickly. It's very rewarding to see my boys enjoying themselves outside and not have the burden of getting bit.

the product is fine but because the customs paper work was not done I had to pay an additional $22.00 which was really disappointing. I will not order again. Between the shipping cost and the custom cost it makes the product more expensive than buying it at the vet.

We have always had great success with using Advantix. I love that it also repels mosquitoes. We just returned from a weekend of camping deep in the woods with our dog with no problems keeping the bugs away. He is a happy pup!

We love this product. We have used it before, and it really works. I highly recommend this product! We have tried different brands of tick treatments in the past, and those products did not work! Our black lab got ticks from those other brands. With this product, he no longer has or had any ticks.

Best flea and tick protection on earth
May 12, 2017
I have been using K9 Advantix for at least 15 years. I have had numerous dogs during that time, and lived in the mountains, the valley, and the desert. I have NEVER seen a flea or tick on any of my dogs during any of that time. They go swimming in the creeks in the summer, running thru the tall grass, and still - no fleas or ticks. Vets often tell me there is a newer greater product on the market but I say No Thanks! This one works and I'm sticking with it.

I've been using this product on my poodle for 2 years and it's been great. We live in town but there are always small squirrels, possum and raccoons in our backyard. The Advantix let's Indy and I sleep better knowing he's protected from fleas and other pests. Thank you.

We've been using Advantix II on our beagles for years. We live in the Midwest so we really need to make sure that our pets are protected from mosquitoes, fleas and ticks. Advantix II has never failed us. Now we have a third beagle and we will be using Advantix II on her as well.

2 MONTH K9 ADVANTIX II BLUE Extra Large Dog (for d
November 1, 2016
Use a flashlight and look through the tubes to see how full. If you can't see how full move or shake it a little bit while looking through the bottle. It should go to the edge before the Eye dropper part. If not full get you money back it could be old. I purchase this and both tubes were only half full one lower than another and the product was not dated it only worked for flies not for fleas. I've also purchased Advantage II another Bayer product that was not full either or dated. The tubes where at different levels. I've block their emails because of this and won't order from them again. they too have this problem with advantage being different levels of fullness. I purchased Advantage II from another company and the tubes are full and dated (the date is a sticker on the tube) and for half the price. Bayer may be giving them old products and they wouldn't know it. I liked the old advantage better than Advantage II and K9. I read on Internet not at this website that frontline was not full tubes for someone that purchased from a different website (same place that I got full tubes). Maybe this is why I got full tubes someone complained or maybe they sell more and it keeps fresher.

I have used this product for over 10 years with all of my dogs. They have not had fleas or ticks at all. They all do hunt work and are definitely exposed to these pests! Would not do without it.

Advantix II it does relieve my dog from itching too much so much so that they can relaxed .Now we applied the second one .

really works well
August 14, 2016
In addition to the flea and tick protection, this product repels mosquitos - a little additional protection against bug-born illnesses. The only negative is that the product is really greasy, and makes a mess wherever the dog lays down. The manufacturer told me that the day after application, the dog's back can be wiped down to relieve this messy business. But it means no petting or snuggling for several days.

For several years, I have been buying my flea treatment from Entirely pets. This has saved me a considerable amount of money over purchasing it at the vet...or even at Costco! Advantix is an excellent product. Entirely Pets is an excellent marketplace

Tried Frontline Plus which was like using nothing but costing $100 for cat and dog. Then, we tried K-9 Advantix and Advantix for our kitty. What a difference. It's been a week and - no fleas, no itching or chewing. Happy pets and pet parents.

This product most effectively protects my dogs against all the most common pest that attack them. I highly recommend it. The only caution is that it needs to be put on with great care, through thick hair and fur, right onto their skin and it must be put on in a way that it is not accessible to their tongues.

I have been using K9 Advantix II for years now. I live in rural Ok and ticks are my dogs worst enemies, we tried many other products over the years and K9 Advantix II really does work the best, plus we live right next to a river and it seems to help with mosquitoes as well. I wouldn't use anything else !!!

My golden retriever is a farm dog, and he's out most of the day in the pasture and the woods, so he's in tick territory a lot of the time. I have tried other spot protection, but none worked as well as K9 Advantix. No fleas and almost no ticks. I highly recommend it.
