I have had no probrems with Advantix YET. Remember in time fleas and ticks build up a resistance to a drug and then it doesn't work so well.

Our dog has had fleas this entire summer. Using this product changed nothing.. I have used this in the past, same dog with very good results. I should have saved my money and picked the fleas off one at a time. I am retired and this would have given me a job. No pay but the dog would have been happy, maybe. I did note the package stated made in China. Perhaps this tells us something.. This product should be taken off the market. It simply does not work. As to side effects, there were no effects period, nada, zero, etc.

This product worked for fleas and tics, however my dog developed immune mediated thrombocytopenia and died. Please read the side effects before administering, I assumed it was safe.

Product is easy to administer, which was seriously the only good thing about it. It did not work. I bought a 3 month supply, for June July and August from the vet. Kept it stored at proper temp. And still have had to bring my dog back to the vet several times to have ticks removed that burrowed too deep for me to get. And my dogs skin is extremely dry from it as well.

Immediately upon application to the shoulder area of my 7 month old, 65 pound Golden, she started running around the living room. She would rub up against furniture, lay down briefly, up and running around briefly visiting her favorite spots but was very agitated. This went on for a couple hours. Looked on line to see similar complaints/concerns. Called my vet, they don't carry this product but urged me to bathe her immediately with Dawn. If that didn't help, bring her in. Fortunately, an apply rinse apply rinse routine proved effective.

Worst $50 I've ever spent.

Do not use this on your pets! Dogs sick. Irritated skin. Fleas still running rampid after 4 days. Back to revolution for me!

Six month supply lasted six weeks for two dogs. Extremely disappointed and will never use product again. Waste of money.

I bought K9 advantix 2 for my shitzu only for her to continue to suffer with a flea problem. My dog Ginger is allergic to fleas, just one flee on her will make her itch herself to the scalp. I bought this product with the catchy label of "repeals and kills" only to find that was quite untrue. I have been putting this product on her every two weeks for the past 4 weeks with consistent baths, scratching never ending. I warn pet owners not to buy this product for the sanity of your pet. Last year I bought her a generic brand at Walmart. She was happy and flee free, not miserable like on advantix. Trust me on this, if you love your pet, don't waste your money.

9 month old maltese neutered male pup. Terrible reaction washed him in dawn 3 times coated him in vitamin e oil. 30 hrs after application still having fits of what vet calls pins and needle feeling. Never again.

We have 6 dogs and today 3 days after treatment 2 of them had fits, collie had never had fit before had a violent seizure lasting several minutes very frightening and couple of hours later terrier who has fitted occasionally had a fit. I have heard advocatt can have this effect but didn't know this did also.

Small Maltese 6 yrs old has had 18 months at vets often, just lies from them she had even developed staph on her skin, advantix is what I believe is the culprit she has been bloody miserable, we will find a different product.

Terrible product. Does not repel fleas at all. I can only imagine what it does to ticks. Will be taking further action to receive a full refund for a product that doesn't work.

I used this on our 14 year old Jack Russell and the reaction was almost immediate. The skin at the application site became red and inflamed. His hair in the area fell out and he suffered from an involuntary movement of his head which went on for at least a week. After a few days we soaked him in an oatmeal bath and the inflammation lessened. I spend $80 on this treatment. It damaged my dog bringing him great discomfort and the other two tubes are unusable. Should be taken off the market.

It may be a coincidence but my healthy 2 year old dog had a seizure 3 days after i applied this product. After reading the reviews here there is a VERY strong link . I will never use this on her again, i only hope this stuff hasnt triggered life time health problems.
The warnings have to be made MORE BOLD on the packaging.

When I use this . I know that my loved pets will be secure to roll in the grass. With being bitten .

My poor little Bischon has had a terrible 3 days since I applied the Advantix.. She was frantic running around hiding under pillows, scratching herself and panting terribly. We we're away on holiday otherwise I would have taken her to my Vet.. We covered her with cold cloths to help stop the heavy panting as she was so overheated.. We never slept for the 3 nites she was very agitated, shaking her head where we had applied the Advantix.
It is now the 4th day, she is still shaking her head but the extreme panting has stopped she has developed a small sore where she has been constantly scratching herself.
I rang the emergency help line and it was explained it would have been like sunburn and the bad reaction can last between 2-72 hours..

I have a 16 year old shihtzu who has a flea allergy, i have always used Advantix that i buy at my vets office. i bought a six month supply and it came with a free tube. I just applied the fourth month dose and it is not working!!! he is covered with fleas and flea eggs!! I can't afford to take him back in and he is too old to just keep applying all kinds of different stuff to him to try to kill the fleas!!! I don't know what to do!! my poor Maxwell is just MISERABLE!!!!!

I used this product for several months on my tan and white beagle puppy. I did not make the connection, at first, that the Advantix was causing skin twitching on his back. By the third month, I could not pat him on the back without the twitch. When I described the problem to my vet, she confirmed that neurological issues were reported with Advantix, particularly in smaller, white dogs. My dog is now almost three years old. The skin twitch lessened immediately following cessation of Advantix, but continues to this day. Not recommended for smaller, white dogs.
