Customer Questions & Answers
-
Question:
What is K9 Advantix II used for?
Answer: K9 Advantix II is a topical treatment designed to protect dogs from fleas, ticks, and mosquitoes. It works by affecting the nervous system of these parasites, leading to their elimination on contact. By using K9 Advantix II, you can help maintain your dog's health and comfort, especially during peak flea and tick seasons. Regular application aids in preventing infestations, making it an ideal choice for pet owners living in infested areas. -
Question:
How do I apply K9 Advantix II to my dog?
Answer: To apply K9 Advantix II, ensure your dog is dry and healthy. Open the tube and part your dog's fur on the back of the neck until the skin is visible. Squeeze the tube gently to apply the entire contents directly onto the skin. Avoid touching the treated area until it’s dry. This method ensures that the treatment is absorbed properly and provides full protection. Frequent use as per instructions maximizes effectiveness in flea and tick prevention. -
Question:
Is K9 Advantix II safe for all dogs?
Answer: K9 Advantix II is safe for dogs weighing between 21-55 lbs. However, it should not be used on cats or pets under this weight range. Always consult with your veterinarian before starting any new treatment, particularly if your dog has underlying health conditions or is on other medications. It's crucial to ensure the product is suitable for your pet's specific needs to avoid any adverse reactions. -
Question:
How often should I apply K9 Advantix II?
Answer: K9 Advantix II should be applied once every month for optimal effectiveness in controlling fleas, ticks, and mosquitoes. Regular monthly applications help break the flea lifecycle and ensure continuous protection for your dog. This schedule works effectively in various climates and helps keep your pet safe from pest-related health issues during buggy seasons or when traveling. -
Question:
Can I bathe my dog after applying K9 Advantix II?
Answer: It’s recommended to wait at least 24 hours after applying K9 Advantix II before bathing your dog. This waiting period allows the treatment to fully absorb into the skin for maximum protection. After this duration, you can bathe your dog, but be mindful of using dog-safe products to maintain the treatment's effectiveness. Following these guidelines ensures your pet continues to benefit from the flea and tick prevention. -
Question:
What should I do if my dog has a reaction to K9 Advantix II?
Answer: If you observe any unusual symptoms such as excessive scratching, lethargy, or difficulty breathing after applying K9 Advantix II, you should contact your veterinarian immediately. Identifying the reaction early is key to addressing any potential issues effectively. Your vet might suggest alternative treatments or conduct a thorough examination to determine the cause of the reaction. -
Question:
What is the difference between K9 Advantix II and similar products?
Answer: K9 Advantix II is unique due to its dual action against fleas and ticks, as well as its efficacy in repelling mosquitoes. Many similar products may focus on treating infestations rather than prevention. The inclusion of multiple active ingredients in K9 Advantix II enhances its effectiveness in keeping your dog pest-free in various environments. This makes it a preferred choice for many pet owners aiming for comprehensive protection. -
Question:
How long does K9 Advantix II take to work?
Answer: K9 Advantix II starts working within 12 hours to eliminate fleas and ticks. Once applied, it quickly spreads across your dog's skin, providing immediate protection. If your dog is already infested, you may notice a decrease in scratching and discomfort within a short time as the treatment takes effect. This rapid action helps to ensure your dog feels comfortable and safe from pests shortly after application. -
Question:
Can K9 Advantix II be used alongside other flea treatments?
Answer: It's essential not to mix K9 Advantix II with other flea treatments unless directed by a veterinarian. Doing so could reduce its effectiveness or increase the risk of adverse reactions. If your dog is currently on another flea treatment and you wish to switch to K9 Advantix II, consult your veterinarian for guidance on the best way to proceed for a safe transition. -
Question:
Where can I buy K9 Advantix II?

They offer a variety of pet care products, ensuring that you find exactly what you need for your furry friend.
