Why I Believe Internal Flea Medicine is Necessary for Dogs

As a dog owner, I have been faced with the challenge of dealing with fleas on my furry companion. These tiny parasites can not only cause discomfort and irritation to my dog, but also spread diseases and infest my home. While external flea treatments, such as shampoos and sprays, may provide temporary relief, I have found that internal flea medicine is necessary for long-term prevention and eradication of fleas.

Firstly, internal flea medicine works from the inside out. It is ingested by the dog and travels through their bloodstream, making it an effective method to eliminate fleas that may be hiding in hard-to-reach areas on their body. This means that even if my dog licks or grooms themselves after treatment, they will still be protected against fleas.

Secondly, internal flea medicine not only kills adult fleas but also prevents their eggs from hatching. This breaks the flea life cycle and prevents re-infestation in my home. It also reduces the chances of other pets or humans in my household getting infested with fleas.

Moreover, internal flea medicine provides long-lasting protection compared to external treatments which can wear off after a few days. This

My Buying Guide on ‘Internal Flea Medicine For Dogs’

As a dog owner, I know how frustrating it can be to deal with fleas. Not only do they make your dog uncomfortable, but they can also infest your home. That’s why finding the right internal flea medicine for dogs is crucial in keeping your furry friend and your home flea-free. After extensive research and personal experience, I have compiled a buying guide to help you choose the best internal flea medicine for your dog.

Understanding Internal Flea Medicine

Before diving into specific products, it’s essential to understand what internal flea medicine is and how it works. Internal flea medicines are oral medications that are designed to kill fleas from the inside out. These medicines are absorbed into your dog’s bloodstream and then spread through their skin, killing fleas on contact.

Factors to Consider

When looking for internal flea medicine for dogs, there are a few key factors to consider.

Effectiveness

The first thing you should look for is the effectiveness of the medication. Make sure to check the active ingredients and their concentration levels. The most common active ingredients in internal flea medicines are lufenuron, nitenpyram, spinosad, and selamectin. It’s essential to choose a product that targets not only adult fleas but also their eggs and larvae.

Age and Weight Restrictions

Some internal flea medicines have age and weight restrictions, so it’s crucial to read the label carefully before purchasing. Giving your dog the wrong dose can be dangerous and may not effectively treat or prevent fleas.

Administration

Consider how easy it is to administer the medication to your dog. Some come in pill form, while others are chewable tablets or flavored liquids that can be added to food or given directly into the mouth.

Safety

It’s essential to choose an internal flea medicine that is safe for your dog. Some products may have potential side effects or interactions with other medications your dog is taking. Always consult with your veterinarian before starting any new medication.

Recommended Products

After researching various brands and consulting with my veterinarian, I have found some highly effective and safe options for internal flea medicine for dogs.

1) NexGard Chewables: This monthly chewable tablet contains afoxolaner as its active ingredient and effectively kills fleas within 24 hours.

2) Trifexis: This monthly tablet has both spinosad (flea killer) and milbemycin oxime (heartworm prevention). It also comes in different weight categories making it suitable for all sizes of dogs.

3) Revolution: This topical solution contains selamectin as its active ingredient, which not only kills fleas but also prevents heartworms, ear mites, sarcoptic mange mites, and certain types of ticks.

In Conclusion

Finding the right internal flea medicine for dogs may take some trial-and-error as every dog reacts differently to medications. Always consult with your veterinarian before starting any new medication for your pet. With this buying guide in hand, I hope you can make an informed decision when choosing an effective and safe internal flea medicine for your furry friend.
