    “I used a leading collar for two years, but it seemed to lose effectiveness after four or five months. Since switching to the Resawell Flea & Tick Collar, its monthly refresh has made a real difference, and my dog has stayed flea- and tick-free.”

    “My Golden spends weekends in the woods, and I used to find ticks constantly. Since using the Resawell Flea & Tick Collar, I haven’t found a single one. Its monthly reset makes sense—why trust a six-month-old collar to remain at full strength?”

    “My vet recommended imidacloprid and flumethrin as the gold standard for flea and tick prevention. Resawell combines both at full clinical strength and is easy to apply and odorless, while my dog doesn’t even notice it.”

    Cecilia G.

    Resawell’s monthly-replacement approach gives your dog a fresh collar every 30 days. The formula combines imidacloprid and flumethrin, with regular replacement at the centre of the routine instead of wearing the same collar for six to eight months.

    Unroll the collar and remove the plastic tabs. Fasten it around your dog’s neck with enough room for two fingers. Thread the end through the loop, then trim the excess, leaving approximately one inch. Adjust the fit to your dog’s neck.

    Each collar is designed for 30 days of use. Replace it monthly to keep your dog’s protection routine consistent.

    Each collar is designed for 30 days of use. Replace it monthly to keep your dog’s protection routine consistent.

    Imidacloprid targets fleas, flea larvae and lice, while flumethrin helps kill and repel fleas and ticks. Together, they help manage existing pests and reduce reinfestation.

    The collar is designed to be odorless and non-greasy. Check the package’s age, weight and fitting requirements before use. If your dog develops irritation or another reaction, remove the collar and contact your Check this link for more information.

    The collar works externally, while supplements are given orally. Compatibility depends on the specific supplement and your dog’s health, so check with your veterinarian before combining products.

    How Does It Work?

      Not Just a Flea Collar—It’s Monthly Protection Reset

      Other collars promise six or eight months of use, but their active ingredients may weaken over time, leaving your dog less protected.

      Resawell is different:

      • Clinical-Strength Dual Action: Imidacloprid and flumethrin kill pests on contact and disrupt their life cycle.
      • Monthly Potency Reset: Monthly replacement keeps protection at peak strength instead of relying on a weakened six- or seven-month-old collar.
      • Complete Lifecycle Control: Imidacloprid targets adult fleas, larvae, and eggs to help prevent reinfestation.
      • Waterproof Full-Body Coverage: The ingredients spread through your dog’s coat and skin and remain effective through baths, swimming, and rain, while staying odorless, non-greasy, and invisible.

      What you’ll notice: No more fleas at home, ticks after walks, excessive scratching, infestations, or costly vet treatments for preventable pests.

      Resawell delivers maximum-strength protection every day of the year.

      Packaging claims: Imidacloprid kills fleas, flea larvae, and lice, while flumethrin kills and repels fleas and ticks.

      3 Simple Steps to Full Protection

      Step 1: Unroll the collar and remove all plastic strips or tabs.

      Step 2: Fasten it around your dog’s neck, leaving enough room for two fingers.

      Step 3: Pull the excess through the loop and trim it, leaving 1 inch—or 2 inches for growing puppies.

      Replace every 30 days for maximum protection.
