What are K9 Advantix Allergies?

K9 Advantix is a popular waterproof, topical agent used to kill and prevent fleas and ticks from infestation on dogs. This product is applied to the dog once a month. K9 Advantix is available in two varieties: the original K9 Advantix and K9 Advantix II. There are differences between the two varieties, as the original K9 Advantix is effective in the prevention and killing of ticks and fleas; however, this original type does not kill the eggs, pupae, and larvae of either pest. In order for K9 Advantix to be effective, the ticks and fleas must hatch first before the product can kill them. 

K9 Advantix II will eliminate the pests in every stage and is highly effective at repelling these pests before they make contact with the coat of the dog. K9 Advantix II also works against mosquitoes, flies, and lice.

Permethrin and imidacloprid are two powerful ingredients in the K9 Advantix products. K9 Advantix II also contains the repellent pyriproxyfen. Upon application, dogs may have side-effects from either type of this product.

K9 Advantix allergies in dogs occur when dogs are exposed to the chemicals within K9 Advantix or K9 Advantix II. The chemicals within the products cause an adverse reaction within the dog’s body, which is marked by a variety of symptoms.

Diagnosis of K9 Advantix Allergies in Dogs

If you suspect your dog is having an allergic reaction to K9 Advantix or K9 Advantix II, it is important to make an appointment with your veterinarian. Once you take your dog to the veterinarian, the medical professional will assess your dog’s symptoms. Your dog may show a variety of symptoms, and the severity may vary depending on the allergic reaction of your companion.

The veterinarian will ask you questions pertaining to everything “new” you have introduced into your dog’s life. He may ask you about various foods, allergens within the home, or anything that you have recently applied to your dog. With those questions, you may come to the conclusion that you recently applied the flea and tick treatment.

Treatment of K9 Advantix Allergies in Dogs

The veterinarian will treat your dog symptomatically. Symptoms depend on your dog, as every dog may react differently. Treatment methods may include:

Fluid Support

If your dog is having a gastrointestinal reaction and has been vomiting or has had diarrhea, the veterinarian may give him fluid support. Fluid support will rehydrate him; fluids may be given intravenously or subcutaneously underneath the skin, usually at the neck area. The amount of fluids given depends on your dog’s size, species, age, and the severity of dehydration.

Decontamination

Decontamination of your dog’s fur and skin is another treatment method to rid your dog of the flea and tick solution. The veterinarian will cleanse the dog with the detergent of his choice and thoroughly rinse your dog. 

Medication

Depending on your dog’s condition, the veterinarian may give your dog medication to lessen the symptoms. Medications may also help detoxify your dog’s system.

Recovery of K9 Advantix Allergies in Dogs

Once it is determined that your dog has an allergy to K9 Advantix or K9 Advantix II, the key to recovery and management is to remove the product from the dog and to stop using the product in the future. Once your dog recovers from this allergic episode, the prognosis is very good.

When you take your dog home, your veterinarian may give you directions on how to care for him in terms of rinsing and cleansing him and applying any topical solutions, if given to you by the veterinarian.

In terms of flea and tick treatment, there are alternatives if your dog is allergic to the K9 Advantix products. Many dog owners seek out natural and holistic flea and tick treatments if their dog is allergic to the commercial brands. It is very important to apply a tiny bit of the solution to only one small section of your dog’s body to see if he has any reaction before you continue to use the product.

Has Symptoms

I usually use advantage on my dog but this month decided to use advantix 2 for ticks. A few hours later he started shaking his head and dropping one of his ears. I cleaned the ear out but it was very clean. Now he continues to shake his head periodically dropping both ears here and there. Both ears are clean and have no smell.

While Advantage contains only Imadacloprid, Advantix 2 contains Imidacloprid, Permethrin and Pyriproxyfen. So it is possible your dog has a sensitivity to one of the new I gradients. More common side effects reported include skin irritation, redness and lethargy. Issues with the ear would not be expected after using this product. I would want to rule out a primary ear issue. It's not always easy to detect an ear infection or a foreign body deep within the ear and we sometimes need to look inside the ear with an otoscope. I would advise a vet check to ensure there is no underlying issue with the ears and go from there.

Little Tired, Vomited After 3 Day Of Application

He runs and chases squirrels when on his walks but when at home he seems tired and does not have a lot of energy. He hasn't been eating a lot either and just vomited after 3 days of application of new flea medicine. Do I need to take him to a vet or should I just give him a bath and see if he does better.

Hello, So sorry to hear about your dog. You can start with giving him a bath. This should start to help pretty quickly. If he continues to vomit and act lethargic, it would be best for him to see your vet. Good luck.
