My Buying Guide on ‘Advantage II Extra Large Dog’

When I decided to take care of my furry friend, an extra-large breed, I knew I needed a reliable flea and tick prevention solution. After doing some research and talking to fellow pet owners, I came across Advantage II for Extra Large Dogs. Here’s a comprehensive guide based on my experience to help you decide if it’s the right choice for your beloved pet.

Understanding Advantage II

Advantage II is a topical treatment designed specifically for dogs over 55 pounds. I was impressed to learn that it not only kills fleas but also targets their eggs and larvae, breaking the life cycle. This means fewer fleas in the long run, which is something I definitely want for my pet.

Key Features

  1. Fast-Acting Formula: From my experience, Advantage II starts working within 12 hours to eliminate fleas. I noticed a significant reduction in scratching and discomfort shortly after application.
  1. Long-Lasting Protection: The treatment lasts for up to 30 days, providing continuous protection. I appreciate not having to reapply every week, which can be a hassle.
  1. Water-Resistant: Even though my dog loves to play in the water, I found that this treatment remains effective even after bathing or swimming, which was a relief.

How to Apply

Applying Advantage II is a straightforward process. I followed these steps:

  1. Ensure the Coat is Dry: Before application, I made sure my dog’s coat was completely dry.
  1. Use the Applicator: The product comes with a convenient applicator. I carefully part my dog’s fur at the base of the neck and apply the solution directly to the skin.
  1. Avoid Bathing Right After: I waited at least 24 hours before bathing my dog to ensure the treatment could absorb properly.

Safety Considerations

It’s crucial to keep safety in mind. I always read the label for any warnings. Advantage II is safe for dogs over 7 weeks old, but I made sure to avoid using it on cats or other animals, as it’s specifically formulated for dogs.

Effectiveness Against Ticks

In addition to fleas, Advantage II also kills ticks. I’ve found this to be particularly beneficial during the warmer months when ticks are more prevalent. However, I always check my dog for ticks after outings in wooded or grassy areas.

Customer Reviews

Before making my purchase, I also looked at customer reviews. Many users reported positive experiences, praising its effectiveness and ease of use. Some mentioned that they noticed a significant decrease in flea-related issues within days, which mirrored my experience.

I found Advantage II to be reasonably priced considering its effectiveness. It’s available at most pet supply stores and online, which makes it convenient for busy pet owners like me.

Conclusion

Overall, I highly recommend Advantage II for Extra Large Dogs if you’re looking for a reliable flea and tick treatment. My experience has been overwhelmingly positive, and I appreciate the peace of mind it provides. Just remember to follow the application instructions carefully, and consult with your vet if you have any concerns. Taking care of my dog’s health is a priority, and Advantage II has certainly made that easier.
