How to open:

  • Be sure tube is at bottom of pouch.
  • Using scissors, cut the pouch across the top and remove tube.

How to apply:

  • Use only on dogs.
  • 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. The entire contents of the K9 Advantix II tube should be applied evenly on the top of the back from the shoulder to the base of the tail. 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.

Frequently Asked Questions

How is K9 Advantix II different from K9 Advantix?

With the addition of an insect growth regulator (IGR), K9 Advantix II kills all life stages of fleas. K9 Advantix II also prevents development of fleas, flea eggs, larvae (maggots), and pupae (cocoons), and prevents fleas on a treated dog from infesting your home.

What is the benefit of repellency?

Repellency helps prevent ticks, fleas, and mosquitoes from attaching, biting or feeding. A repelled parasite doesn’t bite or attach. If it doesn’t bite or attach, it can’t transmit the organisms that may cause disease.

What is the difference between K9 Advantix II and other tick and flea products?

K9 Advantix II repels and kills ticks, fleas, and mosquitoes. It repels biting flies and kills lice, too. Its repellency activity and broad spectrum make K9 Advantix II different from other tick and flea products.

Is K9 Advantix II waterproof?

Yes. There is no need to reapply the product after weekly swimming or a bath. For best results, use a non-detergent shampoo.

Can I use K9 Advantix II on my cat?

No. K9 Advantix II must not be used on cats because of a cat’s unique physiology and inability to metabolize certain compounds.

    I have had 4 dogs in my life. My most recent is a chihuahua named Bella. I have used this product for years. It's very simple to use. Simply open the tube and apply to the back of the dog's neck. I guess it works because I have never had a tick problem with any of my dogs that I used it on. The only downside is the cost. I refer to it as Liquid Gold because it is expensive. There are different doses for different size dogs. The larger the dog, the more it costs, which does make sense. It costs about $10 a dose, and that is the cheapest I have found it. It comes in 2, 4, and 6 doses. There may be more dose sizes available but due to the cost, the most I've bought at one time was I have had 4 dogs in my life.

Of course the more you buy, the less it costs, but 4 doses is the amount of money I wish to pay at one time. So, I do recommend it. My dogs have never had adverse reactions to it and it works. … more

  • Money wasted

    By on

    This medication was a hard and large waste of our money, but most importantly of our pets quality & overall happiness in life. I additionally did the usual kickstart of capstar &/or its equivalent treatments along with usual routine of using flea traps & environmental control rituals of washing their bedding and surroundings etc. This product absolutely did not work for my 2 pets. I even made sure was not the same as last 6 month treatment. (Due to flea possible capabilities to adapt/ evolve/ or strengthened flea immunity it was considered when choosing the product at time of purchase.) Terribly disappointed and frustrated!

  • Best price I found

    By on

    I always get Advantix 11 for our toy poodle I find it works the best. I searched and found that Chewy had it for the best price. I will continue to order from Chewy because they have a good selection and good prices...

  • Disappointed

    By on

    I have a 3 month old puppy I just adopted and this poor baby has really been suffering with fleas. This product did not work in the slightest. I'm really disappointed. He's now waiting on a new medication that I paid extra to over night because I feel so bad for him. Now I'm out the money I paid for this product and he's had to suffer with fleas for no good reason.

  • Have used this product for years on my small dogs

    By on

    I have had many tea cup poodles over the past 20 years and now I have Chihuahua's. I live in a city where everyone has at least one dog or up to four dogs. The population of deer is very high (tic's) I never have to worry about anything bothering my doggies with this protection each month. My dogs are very happy.

  • Dependable flea and tick repellant

    By on

    I've used this product for years on 2 dogs, a Spaniel and a Min-Pin. It is very reliable at controlling both fleas and ticks. Chewy has the best price on this product. I ordered it one day and received it the next day-awesome! I would Chewy .com for all my pet products.

  • Still deciding

    By on

    I am still hesitant about K9 advantage. My dog is picking up fleas here and there with the first application. I am now on 2nd application and still observing. As far as for Chewy I love the service I just wish that they offered better discounted prices.
