What diseases can mosquitoes transmit to your dog?

When it comes to mosquitoes, it’s not just the buzzing and biting that can annoy you and your pet; it’s the bloodsucking, too. By piercing the skin and drinking directly from a blood vessel, mosquitoes’ bites can result in serious consequences that may compromise your dog's health and happiness.

Top questions about K9 Advantix® II
How long after using another topical product do I need to wait before applying K9 Advantix® II?

Please consult your dog’s veterinarian for their recommendation.

 

How long does K9 Advantix® II last?

A single application of K9 Advantix® II keeps working for a month.

 

Can I bathe my dog after applying K9 Advantix® II?

Yes! However, we suggest bathing your dog before applying K9 Advantix® II. Your dog needs to be dry at the time of application.

If you choose to bathe your dog in between treatments, we recommend use of a general grooming shampoo for pets.

 

Can I apply K9 Advantix® II more than once a month?

A single application of K9 Advantix® II remains effective for four weeks. However, if the dog has a severe infestation, retreatment within a month may be necessary. Do not retreat more than once every seven days. After flea control is attained, return to a monthly treatment schedule.

 

Why do I still see fleas after using K9 Advantix® II?

Although K9 Advantix® II kills fleas on your dog, there may still be fleas in your dog’s environment that have since jumped on after treatment. Luckily, with K9 Advantix® II, new fleas are killed within 2 hours with protection against further infestation for at least 4 weeks. As fleas die they are no longer able to stay hidden against your dog’s skin, and therefore you may also be seeing dying fleas coming to the surface of your dog’s fur coat.

 

How long does it take for K9 Advantix® II to work on fleas?

K9 Advantix® II kills fleas within 12 hours. New fleas that jump on the dog from the surroundings, such as grass, carpet and pet bedding, are killed within 2 hours with protection against further infestation for at least 4 weeks.

 

Can my dog go swimming after using K9 Advantix® II?

Yes! Your dog is free to take a dip after K9 Advantix® II has been on for 24 hours. More frequent swimming may keep the product from working for the full 30 days.

 

How does K9 Advantix® II work?

Not all products work the same way: K9 Advantix® II is applied to the pet's skin, spreading the active ingredients over your dog's body to kill fleas, ticks and mosquitoes through contact. No biting required!

 

How do I apply K9 Advantix® II?

Use only on dogs. DO NOT USE ON CATS or other animals. Do not apply to dogs weighing less than 4 lbs.

Remove applicator tube from the package. Use scissors and peel down foil.

Hold applicator tube in an upright position. Pull cap off tube.

Turn the cap around and place other end of cap back on tube.

Twist cap to break seal, then remove cap from tube.

The dog should be standing for easy application. Evenly apply the entire contents of the tube along the top of the dog's back, from the shoulder down to the base of the tail. The number of spots depends on the size and weight of your dog (please refer to the product label). At each spot, part the hair until the skin is visible. Place the tip of the tube on the skin and gently squeeze to expel a portion of the solution on the skin. Do not apply an excessive amount of solution at any one spot that could cause some of the solution to run off the side of the dog. Do not get this product in your dog’s eyes, or allow your dog to ingest this product.
