Flea and tick infestations are some of the most common health issues that dogs face, and they can lead to a variety of uncomfortable and potentially dangerous conditions. From skin irritation to serious diseases like Lyme disease and Rocky Mountain spotted fever, parasites pose a significant threat to the well-being of dogs. Preventive measures, such as oral medications, are essential for effective control. One such medication widely used for protecting dogs from fleas and ticks is Nexgard for dogs. This blog provides an in-depth look at how Nexgard for dogs works, its benefits, potential side effects, and why it’s an essential part of parasite control for pet owners.

The Impact of Fleas and Ticks on Dogs

Fleas and ticks are more than just annoying pests—they can cause a variety of health problems for dogs. Fleas are notorious for causing itching, discomfort, and skin infections. In some cases, dogs can develop flea allergy dermatitis, a condition that causes intense itching and inflammation of the skin. Ticks, on the other hand, can transmit harmful diseases like Lyme disease, Ehrlichiosis, and Anaplasmosis, which can lead to severe complications if left untreated.

Additionally, both fleas and ticks can lead to anemia, especially in puppies and smaller dogs, due to blood loss from excessive feeding. As such, parasite prevention should be a top priority for dog owners to ensure their pets’ health and comfort.

What is Nexgard for Dogs?

Nexgard for dogs is an oral medication designed to prevent and treat flea and tick infestations. Unlike topical treatments that are applied directly to the skin, Nexgard for dogs is a chewable tablet that works systemically. After ingestion, the active ingredient in Nexgard enters the bloodstream and is distributed throughout the dog's body. When fleas or ticks bite the dog, they ingest the active ingredient, which disrupts their nervous system, leading to paralysis and death.

Nexgard for dogs is effective against a variety of tick species, including the black-legged tick (which transmits Lyme disease), the American dog tick, the brown dog tick, and the Lone Star tick. In addition, it provides rapid relief from fleas, killing them within hours of ingestion. This makes Nexgard for dogs an excellent choice for managing flea and tick infestations and preventing future outbreaks.

How Does Nexgard Work?

The active ingredient in Nexgard for dogs is Afoxolaner, which is an insecticide that targets the central nervous system of parasites. When a dog takes Nexgard, the ingredient is absorbed into the bloodstream, where it remains effective for a month. When fleas or ticks bite the dog, they ingest the active ingredient, which interferes with their nervous system, ultimately causing the parasites to die.

One of the key benefits of Nexgard for dogs is its ability to start killing fleas within 4 hours and ticks within 24 hours of ingestion. This rapid action helps prevent the spread of diseases that fleas and ticks may carry and provides quick relief from the discomfort caused by infestations.

Benefits of Nexgard for Dogs

1. Effective Flea and Tick Control

The most obvious benefit of Nexgard for dogs is its effectiveness in preventing and treating flea and tick infestations. Fleas and ticks are a constant threat to dogs, and Nexgard offers a simple and effective way to protect pets from these parasites.

2. Convenient Monthly Administration

Unlike some topical treatments, which need to be applied every few weeks or require careful application to avoid skin irritation, Nexgard for dogs is a chewable tablet that is given once a month. The ease of administration is one of the reasons many pet owners prefer oral medications.

3. No Messy Residue

Since Nexgard for dogs is administered orally, there is no need to worry about greasy or oily residue on the dog’s fur. This makes it a clean, hassle-free option for parasite control, especially for dogs with long or thick coats.

4. Fast Action

Nexgard begins working quickly, killing fleas within hours and ticks within a day. This rapid onset of action provides fast relief for dogs suffering from flea and tick infestations.

5. Palatable and Easy to Administer

The chewable tablet is often flavored to appeal to dogs, making it easy for pet owners to give their dogs the medication without a struggle. Dogs typically consume the medication like a treat, which reduces the stress and effort required to administer it.

6. Broad Spectrum of Protection

In addition to controlling fleas and ticks, Nexgard for dogs helps protect against several types of ticks, which are important to consider given the various diseases they can transmit. Lyme disease, Rocky Mountain spotted fever, and other tick-borne illnesses are common in many parts of the U.S., and preventing tick infestations is crucial.

Potential Side Effects of Nexgard for Dogs

While Nexgard for dogs is generally well-tolerated, there are some potential side effects that pet owners should be aware of:

• Vomiting and Diarrhea: Some dogs may experience gastrointestinal upset after taking Nexgard. This is generally mild and temporary.

• Lethargy: In rare cases, dogs may experience a decrease in energy levels, appearing tired or sluggish.

• Loss of Appetite: A decrease in appetite is another rare side effect, though it usually resolves on its own.

• Neurological Symptoms: In rare cases, seizures or tremors have been reported, particularly in dogs with a history of seizures or neurological disorders.

If any of these symptoms persist or worsen, it’s important to contact a veterinarian to ensure the dog is responding well to the medication.

Important Considerations Before Using Nexgard for Dogs

Before administering Nexgard for dogs, there are several important factors to consider:

1. Age and Weight Restrictions

Nexgard for dogs is typically approved for use in puppies aged 8 weeks and older and weighing at least 4 pounds. Always verify that the medication is appropriate for the dog’s age and weight before use.

2. Health Conditions

Dogs with pre-existing health conditions, especially those with a history of seizures, should be evaluated by a veterinarian before starting Nexgard. It’s essential to discuss any medical conditions or medications the dog is currently taking with the vet.

3. Missed Doses

If a dose of Nexgard is missed, it should be administered as soon as possible. However, if more than a few days have passed, it may be necessary to contact a veterinarian to determine the best course of action.

4. Consistency

To ensure continued protection, it’s important to give Nexgard on a consistent monthly schedule. Missing doses can leave the dog vulnerable to flea and tick infestations, reducing the effectiveness of the treatment.

Alternatives to Nexgard for Dogs

Although Nexgard for dogs is a popular option for flea and tick prevention, there are other methods of control available:

• Topical Flea and Tick Treatments: Spot-on treatments are applied directly to the dog’s skin and provide protection for several weeks.

• Flea and Tick Collars: These collars release chemicals that repel and kill fleas and ticks over an extended period.

• Other Oral Medications: There are other oral medications available that offer similar protection against fleas and ticks.

Each of these options has its own set of benefits and potential drawbacks. Pet owners should consult with a veterinarian to determine which method is best suited to their dog’s needs and lifestyle.

Conclusion

Nexgard for dogs offers an effective, convenient, and fast-acting solution for protecting dogs from fleas and ticks. Its monthly chewable tablet formulation provides reliable protection against parasites, while its ease of use makes it a popular choice among pet owners. While there are potential side effects, they are generally mild and temporary. As with any medication, it is essential to consult with a veterinarian to ensure that Nexgard is the right choice for a particular dog, especially for those with pre-existing health conditions.

Regular flea and tick prevention is crucial for maintaining a dog’s health and comfort. By understanding how Nexgard works and what it offers, pet owners can make informed decisions about the best way to protect their furry companions from the dangers of flea and tick infestations.
