How long does it take for K9 Advantix to start working?

I applied K9 Advantix to my dog yesterday morning, and I'm wondering how quickly I can expect it to start working. We went for a long walk in the park, and I noticed he was still trying to scratch and bite at fleas. How soon should I see the fleas go away, and is there anything more I should be doing in the meantime?

Answer

K9 Advantix typically begins to kill fleas within 12 hours of application, but it may take a day or more to completely eliminate all fleas on your dog. Consistent scratching and biting might continue for a little while as the treatment takes full effect.

  • Fleas can still be visible after initial treatment but should decrease significantly within 24 hours.
  • While K9 Advantix starts working quickly, a complete infestation may require additional environmental treatments.
  • If itching persists beyond a few days, consult with a veterinarian to rule out other causes of skin irritation.

It's important to ensure that your dog's environment—such as their bedding and play areas—is also treated for fleas, as this will help prevent reinfestation. Fleas can still jump onto your dog from untreated areas, so a comprehensive approach is key.

Frequently Asked Questions

  • How soon after applying K9 Advantix can I bathe my dog?

    It's best to wait at least 48 hours after application to bathe your dog. This ensures the product has fully absorbed into the skin and is effective.

  • Can K9 Advantix be used on cats?

    No, K9 Advantix is specifically formulated for dogs and can be toxic to cats. Never apply dog-specific flea treatments to cats.

  • What should I do if my dog has a reaction to K9 Advantix?

    If you notice redness, swelling, or any other signs of an allergic reaction at the application site or elsewhere, contact your veterinarian immediately for advice.
