You should always have ways to protect furry friends from ticks, fleas and other pests. When it's time, make sure to have the Elanco K9 Advantix II Topical Flea and Tick Treatment for Dogs on hand. With a waterproof formula, this dog flea and tick solution offers long-lasting protection against ticks, fleas, chewing lice and biting flies, even after swimming or bathing. This helps to decrease their risk of developing diseases. Not only that, but the flea and tick solution for dogs also eliminates fleas at all their life stages, ensuring pets won't become impacted by reinfestations.How it Works

When you apply K9 Advantage to your pet, it spreads at the hair root level over the skin's surface, assisted by the movement of the body, which provides all-over coverage. This revolutionary chemistry impairs the flea's nervous system, which kills the flea. Since reinfestation is likely to come from outdoors or the pet's environment, those new fleas will also be killed within 2 hours. K9 Advantage protects your pet from further infestation of fleas for up to one month.

Special Precautions

  • Refer to K9 Advantix II Adverse Reactions if your pet experiences any side effects to this medication.
  • Separate dogs for 12 hours following product application, ensuring that the product is completely dry, if your household also includes cats.
Overdose Information

Contact your closest emergency animal hospital.

Side Effects

Rarely, the following side effects have been noted in dogs between six and nine days following application:
  • Unsteadiness
  • Depression
  • Weakness
These symptoms resolved by day ten post-application with no intervention.

The following side effects also occurred during laboratory effectiveness studies after application, and could be attributed directly to this medication. They may also be secondary to the burden of intestinal parasites or other pre-existing conditions.
  • Nasal discharge
  • Ocular discharge
  • Coughing
  • Lethargy
  • Anorexia
  • Vomiting
  • Bloody stools
  • Diarrhea
Reactions at the application site could include:
  • Mild erythema (skin redness)
  • Appearance of white deposits on hair
  • Greasy or stiff hair
These reactions typically resolved without intervention within 2 and 48 hours.

Storage

Don't refrigerate. Store in a dry and cool place.

Tips

Do not handle treated dogs, or allow children to do so, until the site of application dries. You can help ensure this by treating your dog in the evening and not allowing them to sleep with human family members.

  • Available in 2-, 4-, 6- and 12-month supplies of dog flea and tick solution, depending on their weight
  • Topical treatment works to prevent and treat ticks, mosquitoes, chewing lice, biting flies, eggs and fleas for up to 1 month
  • Reapply monthly for complete, year-round protection
  • Works to eliminate the following ticks: American dog ticks (which can carry Rocky Mountain spotted fever) and deer ticks (which can carry Lyme disease)
  • Ideal for use with dogs and puppies 7 weeks of age and older
  • Prevents flea eggs, larvae and pupae from maturing and kills new fleas within 2 hours, ending the flea life cycle and preventing reinfestation
  • Helps to decrease the risk of parasite-transmitted diseases and stress
  • Waterproof formula stays on even after bathing or swimming
  • Convenient, easy application works to kill fleas in 12 hours with same-day efficacy
  • Fragrance-free design allows for gentle use on sensitive skin
  • Note: Avoid handling treated dogs until the medication dries, and keep children from touching dogs, as well; it's recommended to treat pups in the evening and not let them sleep with other human family members or children

Helpful and quick to use

5 hours ago
[This review was collected as part of a promotion.] So far after 3 days there have been no negative side effects from the dose! It is very very small and kept in a tiny container. It makes it easier to distribute onto my dog and get all the spots that i need. The instructions are very clear and helpful. Easy to follow and get complete coverage for my dog since she loves going outside all day. Its easy to open with a top stab thing on the lid. Throw away all together in the trash. Definitely keep away from water and kids and cats! Worked well for my dog very pleased with the product!

[This review was collected as part of a promotion.] We loved this product! It was easy to use and our little guy had no problem letting us put it on him. It didn’t smell bad or weird so that was a plus. I’d absolutely recommend! 0 fleas and ticks
