K9 Advantix Allergies in Dogs

I used this product for the first time after Frontline stop working for my two dogs. They both started acting agitated and restless. I talked with a Bayer representative who told me to bath them with Dawn soap twice, wasted my time bathing them. The reaction from the Advantix II was still there. Called back to Bayer, now the rep said the symptoms would go away in 72hrs after the wash with Dawn, but I was told before the wash the tingling would go away in the same 72hrs and if there were any more reactions I should see my vet. Your product caused these problems and now cause me to spend time and money dealing with my distressed dogs. These Bayer reps are just reading a script and allowing you to vent your frustrations. This product needs to be taken off the market!!! I will be calling to report this product, as we all should do!!!!!!!!!!!!

I’ve had my terrier mix for 10 years now he’s always been fine with Advantix an advantage always been sensitive to flea bites had irritated skin from flea bites so I decided to put them on preventative Advantix up until two years ago I haven’t been able to use Advantix either one of them because he had an allergic reaction and had to go to the emergency veterinarian to treat him for allergic reaction where he was panting restless and huge Hives . I have no idea how to help him what other flea prevention can I give him without risking his life? thank you.

I administered K9 Advantix II for the 2nd time to my one year old dog, Brett. The first time nothing. This time he is experiencing skin irritation and is so miserable. It’s very sad to watch. It’s a weekend so the Vet is closed and I don’t think his symptoms are severe so I’ve followed the advice of your posts. I washed the area with a mild soap and I’ve just given him a Benadryl. Thankfully he’s now resting. I hope he fully recoverers soon. I’m very worried.

I received Advantix 2 from my vet yesterday. Him not taking the time to fully educate me on the risks when I asked, was a red flag I should have heeded. I applied the solution at 10am this morning and after reading horror stories, washed it off with shampoo within 20 minutes of the application. My 12 week old mini doodle who is usually full of energy and loves playing outside, is lethargic and won’t play indoors or outdoors. She just wants to sleep (it’s now 4 hours later). I am praying that I got enough of the solution off of her and that she is fine in a few more hours. I am changing to a holistic vet and look forward to seeing a DR that truly cares for the welfare of my pet, not just the rebate dollars he gets for selling toxic chemicals.

I never leave reviews but I will leave a review about this awful product anywhere I can. Yes it kills fleas, and ticks..and dogs! I have a very healthy dog and almost as soon as I gave her this medicine she started to go downhill fast. She won’t eat, has been vomiting, diarrhea, can barely move won’t even look at you when you call her, can’t even go outside to pee I need to carry her and she even messed herself because she couldn’t make it on her own. Drooling excessively and just so sad she just lays there. I carried her to the bath and washed off this poison. Find anything else to give your dog! After talking with them on the phone they just said to bathe her and take her to a vet if she doesn’t get better. This medicine destroyed my dog. The worse part is that they take no accountability. Truly a terrible experience, after being told to wait it out it is unclear if she will make it.

I had put this product on my dog. I noticed some of it had ran down his back so I wiped it up. Then my neighbors had dumped liquid over my fence onto the ground where my dogs run back and forth. In a couple of days only one of my 4 dogs started getting open sores on his back. I am not certain if it is from the product coming in contact to his back or there was something fungal in what they dumped.

I have given Advantix II in the last few years to my now 6 year old beagle, with no problem. This time, after 24h, he was showing signs of lethargy and he is normally quite active. He also started licking his tail a lot. It has now been 2 days since I gave it, what can I do?
Thanks!

On September 13 very early morning we applied k9 advintix which we’ve have always used before. By late after noon on sept 14 we were rushing my dog to the vet. Not sure if she had a stroke or not. Turns out she has facial paralysis (Bell’s palsy). She can’t blink her right eye and her right side of her mouth is very droopy. Dribbling water when drinking and drooling.
Now due to the potential dryness from not blinking we must apply eye lubricant 4 times daily.

I’m not sure if this was a freak accident or possibly related to her k9 advantix treatment.

I tried K9 Advantix for the second time on my 3 (almost 4) year old Morkie. She is 15 pounds so I used one dosage of the Medium dog kind and immediately she started developing this constant twitching where this was applied in the 3 areas on her back and her back would lock up right and hard. The next thing she’s completely twitching and not able to sleep because of it unless I was massaging her back or the added the weight of my arm was on her. I called the Emergency Bayer phone number as recommended on the box and they told me my dog was experiencing a neurological reaction from the two toxins in this product. They told me she was experiencing a pins/needle sensation and it’s a temporary paralysis of the sub dermis skin layer and to bathe her in Dawn dish soap immediately to remove the chemicals with the detergent in Dawn soap. She went through these side affects for 4 full days but I’m happy that I didn’t lose her or come out with long term affects.

I thought K9 Advantix II was a miracle last year in ridding my 2 Pomeranian's of fleas then. I used it this year as a preventative. Now my 1 1/2 year old is sooo itchy. It breaks my heart. Its been a week with no hope. I used SOOS anti itch shampoo and and have been giving her Benadryl on the daily. No improvement. I took her to the Vet and he said he could offer her a shot that would help with the itch, but he has never heard of an allergy to this. I thought that to be strange. My other 3 year old pom was itchy as the other times they were on it for a day or 2 and it was done. I don't know what else to do for my little one. I don't want to keep running to the vet for no real help. I guess from reading everyone's experience is that I should wait it out the month until it leaves her system?? I wish I saw updates from everyone. I am grateful that she is showing no other symptoms but extreme itchiness.

I have never tried Advantix and to my embarrassment never read about topical treatments before purchase. Puzzled by my dog's twitching and shaking like a leaf, I began to read about Advantix, and it seems like my dog is having an allergic reaction to those pesticides. After reading more about various anti-parasite treatments, I could not believe that the ingredients (carcinogenic neurotoxins) are sold and marketed freely as a safe products. And if anyone tells you that it is harmless, ask them to demonstrate that point by putting that treatment on their child every month. Several of my neighbors' dogs have died of cancer and I blamed that on the pesticide-treated grass, but Bayer and other corporate giants may have been the merchants of death instead.

What are the major neurological and general side effects of K9 Advantix II? I think my dog may be having a reaction. I gave her her first ever dose on 5/16 and about an hour later she started becoming agitated and uncomfortable. She was scratching at her back where I put the application. Maybe 5 hours later her reaction wasn’t so bad but she was still trying to get at her back. Never had these kinds of symptoms in the past when I used Frontline Plus or Revolution so I’m assuming it is something in Advatix that is causing this. It is now 5/19 early in the morning and she is still scratching her back. It is not as bad as he first few hours post application but she still occasionally tries to get at her back. My dog has allergies/dry skin and sensitive skin so I’m used to her scratching but it was the reaction she had after I put the drops that worries me as well as she never really scratches her back normally. Her skin never really turned red or developed hives and she is still drinking, eating, using the bathroom and nearly acting like her normal lively self other than her being uncomfortable in her back region. Not really shaking or sleeping differently either. Sometimes though, and I started noticing this yesterday, she runs and kind of leans to one side like her back is crooked or something. It does not happen every time she runs but when it does happen she doesn’t run far and then sort of stops running to scratch her back so maybe she does that because she’s uncomfortable. She’s not stumbling and her balance is okay, would this classify as neurological symptoms from the medicine, or should I be on the lookout for something else. Also how long would I expect this reaction to last. It has been just about 72 hours since application. When would it be necessary to take her to a vet?

I just applied K-9 Advantix II to my tiny 5month old Schnorkie about 5lbs and she is usually a very exuberant pup but since I gave her the meds on her back she has been very lethargic the complete opposite of her normal self. Please advise. Concerned for my fur baby.

Applied Advantix II as directed (and as I have been doing for years) yesterday, late morning. This morning she threw up her breakfast and, after her walk, took a healthy drink of water which came up about 2 minutes later. Her BM has also gotten quite soft. I can think of nothing else that has changed in the past few days and I'm puzzled by the timing of this.
Right now, I've been giving her small helpings of cooked rice which she has held down so far. For this latest feeding, I added a half of a pack of FortiFlora (a probiotic) to help with the stool issue.
Any other ideas?

I gave my 3 month old shiba Inu and 5 year old papillon k9 advantix the night of two days ago and just this morning the both of them have started itching and biting themselves nonstop!! We’ve used this product on the both of them before. We started to switch my shibas food last night and he threw up his food. Then this morning I woke up to him gagging but he never threw up. That was when both dogs started to itch and I realized that it was probably not the foods fault but the k9 advantix. Help?

We recently rescued an 18-lb.,8 yr old shihtzu that was treated with K9 Advantix II the day we brought him home. He seemed ok for the first few days, but as time has gone on, he has stopped eating,seems lethargic just wanting to lay in his crate/sleep all day. Could this be caused by the K9 Advantix treatment? It was a week & a half ago that he was treated with Advantix, & these symptoms have begun just over past few days. Before this, he enjoyed walking, playing fetch, & was eating ok. Please help!! Thank you.

I applied K9 Advantix II to both of my dogs Thursday night and have used this product before. My boxer has always acted a little weird after but my Shichon has never acted weird. But one Friday my Shichon was very lethargic all day long. He had no energy and didn’t eat or leave the couch. Could this be a reaction to the Advantix II. It was a new box for both. Help!

I put K9 Advantix 2 on my bichon/maltese mix. She is 7.6 lbs. A day after I applied it there was a small raised circle where the medicine was placed. Today, the area looks to be an open rash and bleeding a little. Should I bath the dog and apply peroxide? Will it heal on own?

I gave my do K9 advantix II May and June 21st. July 21st he became very ill. Very lethargic, nausea and vomited once. He will not eat. His fever went to 104. Could this be a reaction to the Advantix? His blood work, xray and ultra sound and normal. The fluid treatment is bringing his fever down.

I applied K9dvantixIi to to my lab on Thursday. On Saturday she became very lethargic and would not eat.. On Saturday I also went to my daughter's house. She has two dogs. They played. Today one of her dogs is acting the same way
Is it possible her dog is having problems because of their contact even if he did not lick the application site?

Hi, I've used advantix on my beagle for 7 years and she seems ok. But after 2 months of using it on my boyfriends 11 year old Shephard he seems to have severe dandruff. Could this be from the advantix? It is also June in New York so it could just be seasonal? Thanks!

My 2 1/2 year old SD (Jr) gets flaking off of his skin where K9 Asvantix has been applied. He is not sick. Nor is he irritated. He eats very well. He is on a LID diet (Allergic to chicken). I wonder if it is caused by the flea meds. And if there are anything else I could give him?

How can I determine my dog is having a toxic reaction to Advantix when the Vets and Bayer are saying its unlikely? My dog was given the appropriate dosage of K9 Advantix II within 2 hours he had liquid diarrhea and vomiting, we were up all night with him. The next day he continued to have loose poop, lethargic, and vomited a couple of times in the morning then was holding down water in the afternoon into the evening. This morning he woke up with bloody diarrhea pouring out of him, lethargic and now is at an ER vet for a plasma transfusion, IV fluids, antibiotics and much more. It is uncertain he will make it through the night. I KNOW what the cause is, but why won't Vets or the company stand up and take responsibility?

I noticed a small area of redness on my dogs side where he is scratching with his back paw. It was after applying the advantex but I'm not completely sure it was from that. It wasn't on the site where applied. So if it may have caused a small skin irritation should I use it again or discontinue using that one? (80lbs dog used 55+ k9 advantix)

I put K9 Advantix II on my 10 lb Pomeranian and by the next day she had explosive and watery diarrhea. I took her to the vet and checked her for intestinal parasites and was clear. We are going on week 3 and the diarrhea is more solid but mushy despite her being on a bland diet this entire time. I had never used this product before and am wondering if it is possible that the Advantix is what is causing her diarrhea? Otherwise she has been fine. Same energy level, same appetite, etc. ideas???

I correctly applied K9 advantix to my healthy 7 year old 70 lb dog. I had used it before with no reaction but this was a newly purchased 4 pack. 45 hours after application he starting breathing heavily, drooling excessively, was very agitated and nervous. I tried to walk him thinking it may help but his hind legs were weak- he had trouble lifting leg to urinate and could not stay in squat position to deficate. Then he threw up clear foam with a few pieces of undigested that must have been from from the night before.I washed his back 3 times thinking he had absorbed the advantix and it was making him sick. he was extremely sick for 12 hours, went to vet who checked for stomach blockage but his did not have a blockage.

I feel this was a reaction to advantix. Any similar stories??

I applied adavntix to my chihuahua last night (used proper dose for his size) almost 2 hours later started itching like crazy and trying to bite and lick the foot he was scratching with. I gave him a bath to wash it all off and some Benedryl on my vets advice. But this morning he is still biting at his foot I did notice a small blister like area on the foot which was not there before treatment. Any advice on what I can do to help ease the foot irritation now!

My dog is 23lbs and is on the large dog formula (21-55lbs) of K9 Advantix II. For the 24 hours after giving her the topical, she becomes lethargic. She still eats, but "mopes" all day and part of the next day. She will play if engaged but would rather lay and sleep for those 24 hours. It resolves after that 24 hour period. I have thought of giving her a dose one lower than her recommended weight but I'm worried about it becoming ineffective. Is this a normal reaction?

How long will allergic reaction to advantix last? I gave my 7 month old pit bull advantix between the shoulder blades as instructured and two days after Hess not eating and has vomited once he's not playful or acting normal

Can previous flea bites still itch and how long? My dog is very sensitive to flea bites. But this isn't the first time you've had a fleas. When he was a puppy he had fleas but then they were not bothering him he didn't scratch he didn't bite himself. Anyways on May 26th the vet told me my dog had fleas. Applied Frontline that day vacuumed that day and have been vacuuming ever since every other day. Had my carpet steam cleaned and been fighting this very aggressively. Prior to May 26th he was scratching a lot for a month couldn't find any fleas so thought this was allergies from the environment. I have switched over to Advantix because they say it repels fleas seems like it's working so far in the last 3 days my dog has scratched maybe once or twice. I use a flea comb on him everyday last two weeks and I might have found two or three fleas although that may mean nothing. So I'm wondering if old flea bites can still cause my dog to scratch

I applied the k9 advantix 5 days ago and noticed that bear is lossing fur and has redness and puss coming out of a the area he also has been itching the area could it be because of the treatment
