Easy and Effective Tick and Flea Treatment
I have used this product over the years, on 5 different dogs (Yorkies and Silky Terriers). All have been house dogs but they are around relatives' and neighbors' dogs frequently and are outside in our backyard or on walks often. I have never seen a flea, even though some months I have completely forgotten to apply the product. In more than 20 years, I think we have had a dog show up no more than 3-4 times with a tick crawling on it or barely attached (probably during one of those months I forgot to apply). I really like using K9 Advantix II because 1) it works 2) it's easy to apply one a month) 3) dogs don't mind it and it's non-irritating to their skin and 3) it's a topical application and not some drug the dog has to take. You do have to wait 24 hours after applying to bathe the dog.

Removed fleas and no rash
This product works surprisingly well for our little dog. Normally we get Frontline but it gave all of our dogs a rash last time. So we were out to try a new product. This one got rid of the fleas and no rash this time. Happy dogs.

The Day the Fleas Packed Their Bags
5 stars. The fleas showed up. They rented tiny imaginary apartments in my dog's fur. Just a quick drop in a few spots. Now the fleas are packing their bags and moving out. Zero stars from the fleas. Five stars from us.

It works
Been using for years. Works great on our animals to keep the fleas out of the house. Wish it was a little cheaper but it works great

Works on fleas
This worked on fleas. Frontline didn’t work, advantix didn’t work. Advantix II was the only thing that killed the fleas.

It works!!
I have been using Advantix for my Toy Poodle for 11 years. His name is Ty and maintains 12 lbs. He came home with a tick last week and the tick jumped right off him and onto the floor. Same 2 other times. They seem to hate the Advantix and get off.I trust the product. Just remember to avoid bathing 2 days before or after. If not, it will affect its efficacy.

EDIT! MONTH 3!
I bought this for my furbaby because I read the labels and did research and everything I found said it really worked but was very strong. Then, I read the 1 star reviews.I panicked and tried to cancel the order but it was too late because I got it same day. So I just researched more about the offending chemical and when I got the order and attempted to use the topical on my dog, but I couldnt get anything out. Call me silly, but I didn't know you had to cut the applicator to open it. Also it was such a small amount, very unexpected.From what I understand, my conclusion is that most of the accounts of sick dogs comes from the dog being able to lick the formula. The neurology problems, chemical burns and tremors, most of this, I assumed, was because the dog ingested it. Chemical burns from putting too much in one spot.Also, I have a pug and her fleas already drive her crazy so the restlessness wasn't new for me. However she did become a lot more vocal. I have these wipes for her that are soothing, and it instantly relieves itchiness. I looked at the places she was itching and use the wipes to sooth the skin.Last night she did scare me a little bit, because I know my dogs eyes and behavior and her eyes were absolutely what you would call "whale eyes" and it looks crazy, and she has the grimace that looks like a smile but its not, like her mouth barely open and she panted for awhile. I just gave her some love and helped her calm down enough to go to sleep.Anyway, we are now on day 2. I havent seen too many fleas come off her yet, but her itchiness has improved, which is shocking to me because I dont see any of the fleas on her bed or floor. The scariest effect so far, has been her whale eyes, and I think its because she's so incredibly itchy and restless. I will update this as we progress. But so far, so good, knock on wood!Edit; month 3 just passed of using this and it really is working very well. By the time it’s time for the next one, you can sometimes tell because you’ll see some fleas on her when she comes back from outside. Other than that, no complaints here!The first day she has it applied, she can get a bit moody with an attitude. But nothing ever severely wrong with her after taking it, other than a little bit itchy.** TRY TO PUT THE SOLUTION ON THE SPINE OF THE BACK WITH THE DOG STILL. THIS WILL MAKE IT IMPOSSIBLE FOR THEM TO LICK IT OFF AND MAKE THEMSELVES SICK! My very sensitive pug has been quite satisfied with this product.

Came with three
So far so good as far as effectiveness goes it’s not a spray. It’s a tiny tube like container. Has a sink, but it’s not too strong. There’s no leakage problems. The value for your money is all right. The appearance is deceiving the boxes. Huge package is tiny. There are seven several different ways you can order them. They come in packages of three 212. I was able to get it within the three hour window so I got it same day.

Buena relación calidad-precio
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.
