When I first started looking for a reliable flea and tick treatment for my small dog, K9 Advantix quickly caught my attention. After using it and researching extensively, I want to share my experience and tips to help you decide if it’s the right choice for your furry friend.
Why I Chose K9 Advantix for My Small Dog
I needed a product that was effective against fleas, ticks, and mosquitoes but also safe for my dog’s size and sensitive skin. K9 Advantix is specifically formulated for small dogs, which gave me confidence that the dosage was appropriate. Plus, it offered broad-spectrum protection that worked well during the warmer months when pests are most active.
What’s Inside K9 Advantix Small Dog Formula?
The active ingredients include imidacloprid and permethrin, which work together to kill fleas and ticks on contact. I liked that it also repels mosquitoes, which is a bonus in my area. The solution is applied topically, so it doesn’t upset my dog’s stomach like oral medications sometimes do.
How to Use K9 Advantix Safely
Applying the drops between the shoulder blades is easy and quick. I always make sure my dog is dry before application and avoid bathing her for at least 48 hours afterward to ensure the treatment stays effective. I also keep her away from other pets for a little while after applying it, just to be safe.
Things to Consider Before Buying
- Dog’s Weight: K9 Advantix small dog version is designed for dogs up to 10 pounds. Using it on a larger dog might not be safe or effective.
- Allergies and Sensitivities: I checked with my vet to make sure my dog wasn’t allergic to any ingredients. If your dog has skin sensitivities, do a patch test first.
- Water Exposure: If your dog swims or bathes frequently, you may need to reapply the treatment more often.
- Other Pets: Since permethrin is toxic to cats, I keep my cat separated during application and until the product dries completely.
