Advantix for Dogs

I accidentally purchased this product last week thinking it was the K9 Advantix II, sadly I found a tick on my dog today after our walk this morning. Today I ordered the right product. I normally use the Advantix II which has never failed us. Show details

Never had any issues for over a decade – Have been giving it monthly to my 12 year old Labrador since he was a 12week old puppy and he's never had any adverse effects, never had any fleas or any ticks either. Living in south east NSW we've had lots of ticks in our area so very glad it seems to have fully protected him from paralysis ticks- especially as there's almost zero tick… Read more

antitoxin in the entirety of australia. Easy application, it does leave an oily/dandruff feeling residue on the coat though which stays there for ages.

Excellent for fly strike dogs ears – Been looking for a product for years which would repel biting flies… treated dogs with Advantix and now no problem with incessant flies biting dogs ears… ears are now completely healed.. can not recommend highly enough Show details

Great product and works perfect for my Bulldog – Great product and works perfect for my Bulldog. I don't understand why this product has bad reviews. My Bulldog got attacked by flies on his ears and nothing worked but this product! I used sprays and creams on his ears and this is the only product that keeps the flies away! Show details

Did nothing – Applied this product to my dog over a week ago, and it has done absolutely nothing. Still see fleas jumping from my dog and frolicking along their merry blood consuming ways. I will never use this product again. Show details

Doesn't Work – I read the directions, followed the directions and nothing. This product did absolutely nothing. My dog gets extremely car sick plus I don't have the money for the vet visit and the expensive flea medicine. Show details

Expensive product that does not work – I used this product on 6 of my dogs. 4 days later I was still finding ticks on ALL my dogs. Did a second treatment 2 weeks later and a week later was still picking ticks off my dogs. These ticks were dug in and alive!!! A lot of money spent for nothing. Will never use it again or recommend it to anyone!! Show details

Burnt a hole in my dogs skin! – After a couple of days my dog was acting strangely! Scratching and rubbing all over the furniture. I thought it was the fleas dying! Turns out he had a huge burn mark on his back where I had applied the Advantix! Poor baby is in such pain. Show details

Use Nexguard – BE AWARE,,, This product does NOT protect against paralysis ticks as claimed. Our dogs got it every 2 weeks as described, and now I have a $4500 vet bill due to 1 dog getting a paralysis tick 1 week after the last treatment. Even the emergency vets said it doesn't protect against paralysis ticks and said Nexguard was a better product. Will never use this garbage again. Show details

Poison – Used half the dose on my husky because I didn't trust it. And so glad I did. Narrowly avoided a costly trip to the emergency vet. If you wouldn't use it on your kids, don't use it on your pets. Show details

Does not prevent fleas – This product seemed to keep fleas away for about a year but in the last 3 months my dog has been infested with fleas. It appears to have no effect at all. I followed the instructions exactly but to no avail. I would not buy again.

Misleading tube dispecers – The tubes are 1mm, unlike other tubes on the market for a 4kg dog only need 0.4mm. Tubes are deceptive to use on small dogs. Seriously bad reaction to dose Show details

Not working – 2 weeks after I applied this product to my dog the correct way, there are big fat attached healthy ticks on my dog. Product not working Dont get why. My vet said it was one of the best treatments available.  Show details

No product in the tubes – Tubes should contain 4 mL of medicine,most only contain 1 mL. I bought 12 tubes and all are the same. I used a syringe to remove product from tube. It takes 4 tubes to get the correct dose for an extra large dog.  Show details

Is not 100% effective. I found a tick on my dog that was engorged – I have been using Advantix 2 for years on my dog. Recently I found a tick on my dog that was engorged. We are in an area where there are Lyme carrying ticks so I am really concerned. I thought it was suppose to be 100% effective. Now I have to wait 5 to7 weeks to see if she shows signs of having Lyme disease. I can't believe this is happening.  Show details

Doesn’t help at all against ticks – I bought Advantix especially to protect my dog from ticks as we are in high tick season and she had so many lately. My dog has 23.3 kg, so is fully in the range for medium dogs (10 kg-25 kg). I applied it properly in the neck and along the spine. That was 4 days ago. She didn’t have a bath or a swim meanwhile. My dog is still full of happy,… Read more

alive, fat ticks. I found 4 ticks alone today, 2 of them fat like a fingernail, so they had a really good meal. The effect of Advantix on ticks is zero! I can’t talk about flees, my dog doesn’t have them, but against ticks Advantix is a waste of money.

Remains oily with lots of residue for days – I have given the amp a good shake before applying and each time I have applied this product it remains oily and tends to run a fair way which I understand is the carier but the residue like dandruff is awful.This continues for more than 2 days. Show details

Poison – My happy and healthy 20 lbs 8 y.o. Havanese have never had issues with any preventative meds until I put this poison on him. Three day later, he is still having seizures, respiratory issues, fever, and depression. In the past three days, we spent one night in the emergency room and today at his regular vet. Stay away from Bayer, Merck, and other… Read more

merchants of death, and buy a good tick collar or chewable alternative instead. And if they ever tell you it is harmless to apply carcinogenic neurotoxins, ask them to demonstrate that point by applying them on their children first.

Product kept fleas away in past. Previously dog was not as energetic after applications but survived – Be cautious useing this product. Last application (around 7pm) caused healthy happy and loving 4 year old cocker spaniel to be admitted to vet hospital. A few hours after application dog became slightly uncomfortable. By next day dogs entire body was tense like he was flexing all of his muscles at the same time. Breathing sounded raspy. He had… Read more

a difficult time panting as he would stop and start panting continuously like he wanted to pant but something was stopping him. Stayed in same spot for 2 days. Would eat and drink if food and water was brought to him. Only went outside to pee when carried. Became paralyzed in hind legs and refused water and food at the end of day 2 (48 hours after application). Day 3 dogs facial expressions, seem like he is ready to go for walks and play fetch but his body is still tense and he can no longer walk. Taken to vet and left there on day 3. The evening of day 2 dog became paralyzed in hind legs. Didnt pee or po for over 24 hours. Could no longer be carried outside due to pain (dog would bite you) On days one and two dog was able to walk but he walked wobbly with legs not in correct position sort of sticking out. Very strange. Dog is at vet now and prognosis is bad if he cannot regain movement of hind legs he will have to be put down. I am in shock as I am not ready to put my dog down he is only 4.

Kills fleas, ticks, and dogs – I never leave reviews, but I hope to save someone the heartache of missing their best friend. My dog is well within the weight limit (6 month cane corso) and has never had health issues. Very healthy puppy. After applying this she could not eat, drink, barely breathe, or move. I had to carry her just to pee. Defecated herself because she's unable… Read more

to move. I called the 1800 and was told to bathe her and take her to a vet. Thanks no thanks! Please find something else to give to your dog

Shih T'zu having a horrible reaction – I bought Advantix on Friday and administered it on my 11 year old Shih T'zu. Throughout the evening and night he was digging at his backside and very itchy, rolling over trying to scratch uncontrollably. He is also twitching and jumps up from his sleep and can't seem to settle. This has been day 3 and the same thing this morning, very itchy,… Read more

biting at his backside and very jerky. I called the vet and was told to watch him. I would never use this product again and I hope this settles down very soon. We have used other products with no problems.

Shih T'zus BEWARE – Put this crap on my poor wee Shih T'zu. Took him for a walk less than an hour later. After 5 minutes he sat down which he Never does on a walk. Coaxed him back up for 100 ft + he did the same thing. 3rd time he lay right down + wouldn't get up. I had to carry him home. He was very lethargic. I bathed + scrubbed him well + rinsed with lots of… Read more

water. Now he is suffering tremors. Most reports I have read that state these symptoms all mention Shih T'zus. Willy's symptoms are: lethargy, weakness in back legs, full body tremors. Hopefully he will eat + drink tomoro.

Disappointing: worked for less than 2 weeks – I applied as directed and did not bathe my crossbreed dog (to avoid reducing its effectiveness) but after 13 days she had a lot of fleas. Will not be buying again. Show details

Great product been using it for 9 years – I been using it for 9 years on my border collie it worked really well. Never have I problem with it. No reaction to treatment flea die in second I think it kill one tick I saw on him that good to know that work. Show details

My Dog Had a Toxic Reaction – We purchased the product on a recommendation from the people at our Local Petco Store. The product is very expensive and made our dog sick. After a $90 Vet visit he told us this product should not be sold. In essence it created a Toxic reaction in our dog. We now have to wait and see if the condition worsens or may get better. The Vet said we will… Read more

not know for another 48 hours. Heartbreaking to see how our dog is reacting to this poison. I would not recommend this to anyone.... I cant even find a way to reach someone at the company. All you get is an outside Vet line. I do't want a Vet line. I want to speak to the manufacturer. So I am out of pocket $140.00 for Product and visit to the Vet and have nothing but a sick dog.

Only repeled insects to face and into ear! – I bought the 2-pack and I put this on my dog who was scratching and itching and had hair missing from pea-sized spots along his rib cage. Within about 12 hours, he stopped scratching around his rib cage, where he had been infected. But after about 15 hours, he suddenly started scratching his face. He was scratching his face for about 2 days. … Read more

Then he developed an infected bubble, about pea-sized, on his face! And every day over the next week, his scratching of his face increased, and he developed another pea-sized spot where his hair was missing, in addition to the infected pea-sized spot about an inch or so away, which was now healing. Over the following 2 weeks, the itching increased to what it was before the application.

I returned the batch to the Petco where I had bought it. I asked if it was expired. They tried to research the Lot No. on the box, but could find no decoder for the Lot Np., and they found a claim that K9 Advantix II does not expire.

I was skeptical, since so many people gave positive reviews. I could not help but wonder if I got a bad batch or if the effectiveness had expired...maybe the Lot No. could show the date that medicine was manufactured. But I could find no help.

So Petco let me exchange the remaining medicine for one that seemed to have a Lot No. with letters further down the alphabet (which I hoped was an indicator that it was more recently manufacture).

The new box Lot No. was KP0D26F KP0C5DU.

I applied the new box medicine. And this time, since I applied the medicine as the instructions indicated, along the dog's back, resulting in the dog being attacked in the face... I decided to begin the application closer to new problem area, and applied it at the back of his head and down his neck as well as between his shoulder blades and down his back.

After about 12 hours, the dog began shaking his head, and scratching at his ears. He reminded me of a kid who got water in his ears after swimming.

It looked like the bugs were now fleeing (no pun intended) into his ears!

It has now been 4 days since the application. The dog was scratching at his ear vigorously and shaking his head with fervor for 3 days. And now he his scratching at his whole body all the time.

What in the world?!!!

I spent a week researching fleas, ticks, the lifecycles, the medicines for pets; and I feel like an expert. The dog has been isolated to a linoleum section of the house for about 6 weeks now, with his bedding being changed and washed in hot water every week. He was being washed weekly until the first application of K9 Advantix II, a month ago, when we put off bathing him to every 2 weeks (he has not been bathed since the 2nd application of K9 Advantix II, 4 days ago).

I called the phone number on the K9 Advantix II box this morning, and the woman who answered, kept trying to avoid my questions about the product and about any additional information that the Lot No. might give me, and instead kept trying to educate me on flea and tick life cycles. When I interrupted the lesson to ask her to answer my question instead, she put on her supervisor. After being on hold for 8 minutes, and asking the supervisor about the meaning of the Lot No., she also began a lesson about the flea life cycle. And when I pointed out that she was changing the subject, and asked her (a supervisor) if she could just answer my question about the meaning of the Lot No. I gave her, she said, "Maam, if you continue to be this way, I'm going to have to terminate this call." I was struck dumb at the lack of diplomacy and disinterest in actually answering my question about the product's effectiveness if it might be expired and about decoding Lot No. for me. I was not interested in her changing the subject and forcing me to sit through yet another flea life cycle lesson, which I did not need. All I could say was, "Oh, wow." And I hung up in defeat.

My poor dog is not being helped by the K9 Advantix II medicines we got from Petco. THE MEDICINE JUST SEEMS TO REPEL THE INSECT(S) TO THE NON-TREATED AREA: first to his face, and then, when I applied the product about a month later to the back of the head, into his ear. And now he's itching the rib cage again.

He hasn't had a problem like this before.

I'm trying Frontline Plus next.
