K9 Advantix Flea, Tick, and Mosquito Protection for Dogs

K9 Advantix

Brand Overview

K9 Advantix is a topical ‘spot-on' treatment combining permethrin and imidacloprid to protect dogs from fleas, ticks, lice, mosquitoes, and biting flies. Permethrin repels and kills ticks and mosquitoes, while imidacloprid kills adult fleas. Applied once a month, K9 Advantix provides fast-acting, water-resistant protection for dogs from 7 weeks of age (weighing at least 1 kg). Its unique formulation deters mosquitoes and biting flies, making it especially useful in regions with mosquito-borne diseases (e.g., heartworm) or fly-transmitted conditions (e.g., sandfly dermatitis).

Key Benefits

Multi-pest protection: Kills fleas, ticks (including Ixodes scapularis, Rhipicephalus sanguineus), lice, and repels mosquitoes and biting flies. Rapid kill: Imidacloprid begins killing fleas within 6 hours; permethrin starts repelling ticks and mosquitoes immediately on contact. Water-resistant: Maintains efficacy after swimming or bathing (avoid water exposure for 48 hours post-application). Monthly convenience: Single application covers multiple ectoparasites, reducing the need for separate treatments.

Usage & Dosage

Use the appropriate K9 Advantix pipette based on body weight:

• K9 Advantix for Small Dogs (1 – 4 kg): One 0.4 mL pipette monthly.
• K9 Advantix for Medium Dogs (4 – 10 kg): One 0.8 mL pipette monthly.
• K9 Advantix for Large Dogs (10 – 25 kg): One 2.5 mL pipette monthly.
• K9 Advantix for Extra Large Dogs (25 – 40 kg): One 4.0 mL pipette monthly.

Part the fur at the base of the neck and apply the entire pipette contents directly to the skin—never apply to the coat. Do not bath or swim the dog for 48 hours after application to ensure optimal absorption. Repeat every 30 days to maintain efficacy. If your dog gains significant weight between applications, switch to the appropriate pipette size at the next dose.

Safety & Considerations

K9 Advantix is well tolerated; mild local reactions—such as temporary hair loss, redness, or itchiness at the application site—may occur. Synthetic pyrethroids (permethrin) are highly toxic to cats; ensure no treated dog contacts cats until the application site has dried completely. Avoid contact with the eyes and mouth; if accidental ingestion occurs, seek veterinary advice. Not suitable for puppies under 7 weeks or dogs weighing less than 1 kg. Pregnant and lactating bitches can be treated, but consult your veterinarian first. Keep unused pipettes in original packaging in a cool, dry place, away from direct sunlight and children.

Frequently asked questions

How quickly does K9 Advantix start working?

Imidacloprid kills fleas within 6 hours of application, and permethrin repels and kills ticks and mosquitoes on contact.

Can I bathe my dog right after applying K9 Advantix?

No—wait at least 48 hours post-application to ensure full absorption and sustained efficacy.

Is K9 Advantix safe for dogs with sensitive skin?

Some dogs may experience mild irritation; monitor the application site and consult your vet if persistent redness or itching occurs.

Can I use K9 Advantix and Frontline Plus interchangeably?

Both products contain imidacloprid, but only K9 Advantix contains permethrin (to repel mosquitoes and ticks). Do not use both simultaneously to avoid overdosing imidacloprid.

What if my dog licks the application site?

If the dog licks the site before it is dry, mild gastrointestinal upset may occur. Ensure the application site is dry and inaccessible until fully absorbed.
