What to know before buying

  • The listing says external use on dogs only and not to use on cats. It also says to keep the product out of reach of children. It claims waterproofing starts 24 hours after application, not immediately.

Listing details to confirm

The listing's dog-weight instructions conflict: the title says X-large dogs over 55 pounds, while a feature specifies 21–55 pounds. Confirm the correct weight range for this exact package before applying. The title and description also disagree on whether the size is X-large or extra large, and the listed breed-size field says Large. Follow the package label, which the listing instructs buyers to read before each use.

Who is it for?

A good fit for

  • Dog owners seeking a topical treatment that the listing claims addresses fleas, ticks, mosquitoes and several other pests.
  • Buyers who want a six-dose pack and can verify that its weight range matches their dog.

Less suited to

  • Cat owners, since the listing says not to use this product on cats.
  • Buyers unable to confirm the correct weight range from the package label or seller.

Customer feedback praises ease of application and mosquito prevention, while reports about flea control, overall effectiveness, duration, value and skin effects are mixed. Some customers report month-long protection and no irritation, while others say the treatment did not last or work for them and describe itching. That variation matters because the listing's up-to-30-day claim is not a guarantee of an individual dog's experience. Confirm the weight range and monitor your dog for reactions.

Positive themes

  • Customers report that the drops are easy to apply.
  • Customers appreciate the mosquito-prevention capability.

Mixed feedback

  • Customers disagree about flea prevention and overall effectiveness.
  • Reported duration varies, from month-long protection to claims that it did not last.
  • Feedback on value and skin effects is mixed, including reports of itching and reports of no irritation.
