Bye-Bye Bugs, Hello Happy Pup 🐾🛡️
K9 Advantix II keeps fleas, ticks, and mosquitoes far away from my small dogs. Easy to apply, vet-recommended, and works fast — no more itchy, grumpy pups. Peace of mind for me, tail wags for them. Highly recommend if you want a pest-free pooch.

After half a year of fleas, switching to this product completely got rid of them!
Cannot recommend enough! I live in the middle of the mountains next to a large national forest. There's deer, beer, turkey and all sorts of wildlife moving through my yard and in the woods year round, visibly agitated by fleas. My dog of 14 years finally got fleas (she's an inside dog with lots of outdoor playtime), as I've been thorough with checking her fur during brushings and baths. I usually just give her monthly flea baths which sufficed, but after a neighbor clear cut their property I've had an influx of wildlife on my property and I think that contributed to my dog getting fleas, I'm not sure. Regardless, she had fleas and they became an irritating presence within my home. Unfortunately, there's plenty of carpet for them to hide in and lay eggs. Yuck! I tried everything to get rid of them! Carpet powders, flea baths (different brands), furniture spray, cheap flea drops.. nothing worked. I battled with them for almost 6 months!! My poor dog was waking up constantly scratching and pacing back and forth throughout the house. I felt like an awful parent and was going crazy before finally deciding to look into the more expensive options.. Now, considering how much I spent on cheaper alternatives that didn't work or get rid of the problem at the source, I really wish I would've went straight for the higher priced option first. Within a matter of weeks of using this product I saw a quick decline in fleas inside the house and on my dog. Within one to two months, they were completely gone! I was in complete shock. I cannot praise this product enough. Maybe it's so effective on the fleas in my area since I live in the rural countryside where they're not used to it, as opposed to city fleas, so your mileage may vary. But for me this was a miracle product and I will be using this as a preventive measure in the summer months, with a periodic dose in the winter. If you struggled with fleas for months and months like I have, you will know the complete relief that comes with a flea-free home. Don't skimp! It may be more expensive than the alternatives but trust me with I say I tried all of them and nothing came close to getting rid of them, whereas this treatment was so fast and effective I was left nearly crying when I saw my sweet dog sleeping soundly through the night. :)

Does not kill fleas
I have used these for years and the last 3 months supply has been a disappointment they are not killing the fleas at all. My babies still have fleas crawling all over them after application. I will no loner be buying this product.

Thankfully, it works!
We have fought fleas on all fronts in our hot and muggy rural area. Frontline and the generic version- useless. Sprayed the land, treated our home, sprayed our dog with an additional temporary spray. This is the first time we've ever had such problems. Dog was constantly scratching, visible fleas and flea dirt. Flea comb simply full of mature fleas and flea dirt. Two vet visits in which we were told the next step was a yearly and expensive treatment. Thankfully, found this on Google as vet recommended. Bought a dose here. It arrived yesterday and we immediately applied as directed to 15 lb dog. He was fine upon application. No major problems afterwards but did began to claw himself aggressively and nip at his paws. Found those relatively minor results on the carton safety data and saw no reason to be overly concerned. I did give him the dose of antihistamine as prescribed by our vet. I think the fleas were 'abandoning ship'! He became drowsy within about 40 minutes settled down and slept soundly all night. No raw spots or other problems today but he looks like a newer, improved dog today. He is basically white. Today there were no visible fleas or flea dirt. Yes! So glad we found this product, all I will buy again! Great customer support because I called the # on the product box today just to check his reaction. They were great.

Great flea treatment
Amazing product. The only brand I use to keep fleas of my Lil guy. Works fast and last a long time. Makes him a Lil lethargic on the first day of applying. But back to normal the next day. Keeps the fleas at bay an is waterproof

Durability and usefulness claim is wrong.
We'll moved out to the country from the city and my dog never had fleas in the city. But out here in the country, it seemed the fleas love him. I bought this stuff on December the 12th applied it immediately. today is December 27th if you see the pictures that I've posted with this review I've already picked multiple fleas off my poor dog And there's tons more flea dirt all over places. Disappointed that this name brand flea medication hasn't even lasted its 30 days. I mean, yes, it worked for a brief period like two weeks, and then now the fleas are back. So I'm gonna go ahead and reapply it, but I'm not purchasing this brand again. I'm gonna try something else. im very disappointed and my poor dog is just as itchy as before the 1st application.

It worked
Tried collars, didn't work. flea baths only got rid of the fleas currently on the dog.. Finally, figured out what part of the house kept causing the issue. Treated the furniture, carpet and then applied the advantix II. After 3 days our dog stopped itching. Haven't seen a flea since. Totally worth it.

En la caja vienen 6 pipetas, como se indica en la descripción: 4 de ellas vienen en el sobre hermético de la propia caja y las otras 2 vienen sueltas (la caja realmente es de 4). Contenta con la calidad de Advantix, no me arriesgo a probar con otra marca. Muy recomendado por la relación calidad-precio.

Llego en la fecha comprometida. Aparte traia un pequeño detalle, que es de agradecer, con unas chuches para el rey de la casa, para que el "trago" de la desparasitazación sea más dulce.
