Yes, K9 Advantix II for dogs is a perfectly safe flea and tick control product. It is specifically formulated for canines, and when used according to the manufacturer’s (Bayer) guidelines, it is safe and efficient. 

Namely, the product is made exclusively for external use and is supposed to be used on dogs and puppies over seven weeks of age and over 4 pounds of body weight. 

K9 Advantix II is an over-the-counter monthly flea, tick, and mosquito treatment. However, it is always advisable to consult with your trusted veterinarian before using any product. Based on where you live, your dog might need year-round flea and tick products and medications. 

Is K9 Advantix II a Good Flea Medicine?

Yes, K9 Advantix II for dogs is a good flea medicine. Generally speaking, for a flea product to be labeled as good (effective), it must kill between 98% and 100% of the fleas within 12 hours of application and then prevent new infestations for at least four weeks. 

K9 Advantix II for dogs fits this description and is considered a good flea medicine. The product kills fleas in all life stages (eggs, pupae, larvae, and adults) and is efficient against several other ectoparasites. For example, K9 Advantix II repels and kills ticks (American Dog Ticks, Lone Star Ticks, Brown Dog ticks, and Deer Ticks), chewing lice, mosquitoes, and biting flies (sand and stable flies). 

This broad-spectrum protection is important as external parasites are responsible for various vector-borne diseases in dogs. Here is a list of some internal parasites and diseases dogs get from fleas, ticks, and other ectoparasites:   

In addition to transmitting pathogens, external parasites can inflict painful bites and local skin irritation at the bite site. Additionally, in sensitive dogs, fleas may trigger an allergic reaction called Flea Allergy Dermatitis (FAD).

K9 Advantix II Active Ingredients

K9 Advantix II for dogs features three active ingredients: Imidacloprid, Pyriproxyfen, and Permethrin. They all act similarly by targeting the nervous system of the ectoparasites, which ultimately leads to their death.

What are the Side Effects of K9 Advantix II for Dogs?

On rare occasions, K9 Advantix II may trigger a gastrointestinal upset like vomiting and diarrhea or local skin irritation at the application site like burning, tingling, and itching sensation followed by redness and numbness. Other reported side effects include lethargy and/or agitation. 

The risk of side effects by K9 Advantix II for dogs is very low. However, individual sensitivities are always an option when using a pesticide product. Therefore, it is highly advisable to monitor your dog after application. 

In case of adverse reactions, wash your dog with a detergent-based soap, ideally, Palmolive or Dawn. Then call your veterinarian or the Bayer Emergency Support Line for treatment advice. 

K9 Advantix II for Dogs Dosage 

K9 Advantix II Dosage for Dogs

K9 Advantix II for dogs is available in four different dosage versions for different weight and size categories. Here are the K9 Advantix strengths: 

For dogs weighing over 55 pounds, it is not advisable to use more than one K9 Advantix II tube per treatment. 

If you forgot to administer the K9 Advantix II monthly dose to your dog, apply it as soon as you remember and then continue with the determined monthly schedule. You must never double-dose your dog, as overdoses are possible. If you suspect a K9 Advantix II overdose, call your vet or Poison Control Center immediately. 

A single K9 Advantix II application gives protection for up to one month, or four weeks. However, when dealing with cases of severe pest infestations, it is recommended to give more than one dose per month.

K9 Advantix II for Dogs Usage Guidelines

Once you have the K9 Advantix II product you need to know how to use it correctly. First of all, we must recommend careful handling and washing the hands after use. Also prior to application, the dog needs to be dry for a minimum of 24 hours and while applying the solution, be careful not to get any liquid into the dog’s eyes and mouth.

With these precautions in mind, follow these steps to open the product: 

  • Remove the foil from the original package 
  • Use scissors to open the foil and draw the applicator tube 
  • Hold applicator tube in an upright position and pull cap off 
  • Turn the cap around and place it with its other end on top of the tube
  • Twist cap, break the seal, and remove the cap. 

Once the tube is opened, for easy application, follow these guidelines: 

  • Keep your dog in a standing position 
  • Divide the dog’s fur into two sections to expose the skin 
  • Place the tip of the tube directly over the skin and gently squeeze
  • Repeat on several spots until you have used the entire contents of the tube. 

The liquid needs to be evenly applied in different spots located between the top of the back to the base of the tail. For smaller dogs, you can divide the entire contents into two or three spots and for larger dogs into four to six spots. 

Avoid applying an excessive amount of solution on one spot as it will get into the fur or run off the side of the dog. Applying a larger portion of the solution on one spot may also cause local irritation. 

If you have a cat, make sure it stays separated from your dog for at least 24 hours after using K9 Advantix II. Cats cannot metabolize some of the active ingredients in the product making it potentially toxic. 

Finally, a word or two on storage. For maximum efficacy, always store the K9 Advantix II tubes in a cool and dry place. To prevent hazards, keep the unused tubes in their original package and out of the dog’s reach. Also, dispose of the empty tube safely in a dog-proof trash can.  

How Long After Applying K9 Advantix II can I Touch My Dog?

Ideally, you can touch your dog two days after applying K9 Advantix II. This is because the product’s remnants stay on the dog’s skin for a max of 48 hours, and Bayer suggests not to touch your dog until the product is entirely absorbed.  

Does K9 Advantix II Kill Fleas Already on Dogs?

Yes, K9 Advantix II kills fleas that are already on dogs. However, keep in mind that flea control products cannot stop fleas from jumping from the environment onto the pet. Instead, they will kill the fleas after they jump on the dog. 

How Long Does it Take K9 Advantix II to Kill Fleas?

K9 Advantix II kills fleas within 12 hours of application. It needs two hours to kill re-infesting fleas from the environment and protects dogs from future reinfestations for one month, or four weeks. 

How is K9 Advantix II Different from K9 Advantix?

K9 Advantix II offers more superior prevention and treatment than K9 Advantix because it features an added active ingredient  Pyriproxyfen which is an Insect Growth Regulator that is potent against all parasitic life stages, including eggs, larvae, adults. 

Other than that, both products are very similar. They are both formulated and manufactured by Bayer and belong to the same line of products. However, K9 Advantix is the brand’s primitive version, while K9 Advantix II is the improved formula.
