Customer Questions & Answers

  • Question: What is K9 Advantix II XL and how does it work?

    Answer: K9 Advantix II XL is a veterinarian-recommended topical treatment designed for dogs weighing over 55 lbs. It effectively repels and kills fleas, ticks, and mosquitoes. The formula contains active ingredients that disrupt the life cycle of these pests, not only killing the adult insects but also preventing future infestations. When applied to your dog's skin, it spreads across the body through the skin's natural oils, providing continuous protection. This makes it ideal for dogs living in areas with high pest activity, ensuring your pet stays comfortable and protected.
  • Question: How often should I apply K9 Advantix II XL to my dog?

    Answer: K9 Advantix II XL should be applied once a month for optimal protection. Regular application is crucial, as it maintains a barrier against fleas, ticks, and mosquitoes throughout the month. In addition, if your dog swims or gets frequent baths, consulting your veterinarian about the best application schedule is advisable. This is particularly important for active dogs who may be exposed to ticks and other pests during outdoor activities.
  • Question: Is K9 Advantix II XL safe for my dog?

    Answer: Yes, K9 Advantix II XL is considered safe for dogs over 55 lbs when used as directed. It's specifically formulated for larger breeds and has undergone rigorous testing to ensure its safety and efficacy. However, it is important to avoid using this product on cats or dogs under the specified weight, as it can cause adverse effects. Always consult your veterinarian prior to beginning any new treatment to ensure it's appropriate for your dog’s individual health needs.
  • Question: What are the active ingredients in K9 Advantix II XL?

    Answer: K9 Advantix II XL contains three active ingredients: imidacloprid, permethrin, and pyriproxyfen. Imidacloprid works by targeting the nervous system of insects, leading to paralysis and death. Permethrin repels and kills ticks and mosquitoes on contact, while pyriproxyfen inhibits the development of flea eggs, preventing future infestations. This combination makes K9 Advantix II XL a powerful solution for maintaining your dog's pest-free status.
  • Question: Can K9 Advantix II XL be used in conjunction with other treatments?

    Answer: It is essential to consult your veterinarian before combining K9 Advantix II XL with other flea and tick treatments or medications. Some products may interact negatively, leading to increased risk of side effects or reduced effectiveness. Your vet can recommend a comprehensive pest control strategy tailored to your dog's unique needs and lifestyle, ensuring maximum protection against pests.
  • Question: What should I do if my dog has an adverse reaction to K9 Advantix II XL?

    Answer: If you notice any unusual behavior or symptoms such as excessive scratching, redness, or swelling at the application site, contact your veterinarian immediately. It's crucial to provide them with details of when the treatment was applied and any other products your dog is currently using. Prompt action can help address any potential issues and ensure your pet's safety and comfort.
  • Question: How does K9 Advantix II XL protect against mosquitoes?

    Answer: K9 Advantix II XL offers effective mosquito protection by repelling these pests before they can bite your dog. The permethrin component works to keep mosquitoes at bay, reducing the risk of mosquito-borne diseases such as heartworm. This is particularly beneficial for dogs that spend a lot of time outdoors or in areas where mosquitoes are prevalent during warmer months.
  • Question: Where can I buy K9 Advantix II XL in Turks and Caicos?

    Answer: You can purchase K9 Advantix II XL from Ubuy in Turks and Caicos. Ubuy is a reliable online retailer providing a convenient shopping experience, making it easy to find veterinary-recommended products for your pet’s health and well-being.
  • Question: Is K9 Advantix II XL waterproof?

    Answer: Yes, K9 Advantix II XL is designed to remain effective even after exposure to water. While it retains its efficacy after your dog goes swimming or is bathed, it's still recommended to wait a few days after applying the treatment before bathing your dog to ensure full absorption. This allows the product to establish its protective barrier, giving your dog optimal defense against fleas, ticks, and mosquitoes.
  • Question: Can I use K9 Advantix II XL on puppies?

    Answer: K9 Advantix II XL is not suitable for puppies under seven weeks of age. It's formulated for adult dogs over 55 lbs, and younger dogs may need specially designed treatments. Always consult your veterinarian to find the most appropriate flea and tick prevention products tailored to puppies' specific age and weight.
