If you’re a dog owner, you’ve likely heard about the importance of flea and tick prevention. These pesky parasites not only cause discomfort but can also transmit serious diseases to your furry friend. One popular solution on the market is NexGard, a highly effective flea treatment for fleas and ticks. But what exactly does NexGard do to dogs? Let’s dive into the details.

What is NexGard?

NexGard is a veterinary-prescribed medication designed to protect dogs from fleas and ticks. Manufactured by Boehringer Ingelheim, this chewable tablet is known for its palatability and ease of administration. NexGard’s primary active ingredient is Afoxolaner, an insecticide and acaricide that targets the nervous systems of these parasites, ultimately killing them.

How Does NexGard Work?

Active Ingredient: Afoxolaner

Afoxolaner is a member of the isoxazoline class, which works by inhibiting the function of specific neurotransmitters in fleas and ticks. This disruption in their nervous system leads to paralysis and death of the parasites.

Mechanism of Action Against Fleas

Once your dog ingests NexGard, Afoxolaner is rapidly absorbed into the bloodstream. When fleas bite your dog, they ingest the blood containing Afoxolaner, which affects their central nervous system and kills them within hours.

Mechanism of Action Against Ticks

NexGard is equally effective against various tick species. It works by disrupting the neurotransmission in ticks, leading to their death before they can transmit any diseases to your dog.

Benefits of Using NexGard

Effectiveness in Flea and Tick Prevention

NexGard is proven to be highly effective in killing adult fleas before they can lay eggs and in controlling tick infestations. This makes it an excellent choice for preventing both flea infestations and tick-borne diseases.

Ease of Administration

One of the biggest advantages of NexGard is its chewable form, which most dogs find tasty and easy to consume. Unlike topical treatments, there’s no mess, and you don’t have to worry about the product washing off.

Safety Profile

NexGard is FDA-approved and has a well-documented safety profile. When used as directed, it is safe for most dogs.

Dosage and Administration

Recommended Dosage for Different Dog Sizes

NexGard comes in different dosage strengths suitable for dogs of various sizes. It’s essential to administer the correct dosage based on your dog’s weight to ensure efficacy and safety.

How to Administer NexGard

Administering NexGard is straightforward. Simply give your dog the chewable tablet once a month, either with or without food. It’s that easy!

Safety and Side Effects

Common Side Effects

While NexGard is generally safe, some dogs may experience mild side effects such as vomiting, diarrhea, or lethargy. These symptoms are usually short-lived and resolve on their own.

Rare but Serious Side Effects

In rare cases, more severe side effects such as seizures have been reported. If your dog shows any unusual symptoms after taking NexGard, contact your veterinarian immediately.

Contraindications and Precautions

NexGard should not be used in dogs with a history of seizures or in pregnant or lactating females without veterinary advice. Always consult your vet before starting any new medication.

Comparing NexGard with Other Flea and Tick Preventatives

Oral vs. Topical Treatments

Oral treatments like NexGard are convenient and eliminate the risk of washing off, unlike topical treatments. However, some owners may prefer topical solutions due to concerns about oral ingestion.

Comparison with Other Oral Treatments

NexGard is often compared to other oral treatments like Bravecto and Simparica. While all are effective, the choice may depend on factors like duration of action and individual dog tolerance.

Comparison with Topical Treatments

Topical treatments like Frontline and Advantage are also popular. These treatments are effective but can be messy and less convenient than chewables like NexGard.

Effectiveness of NexGard

Clinical Studies and Trials

NexGard has undergone extensive clinical testing, demonstrating high efficacy in killing fleas and ticks. Studies show that it begins working within hours and maintains its effectiveness for a full month.

Real-World User Experiences

Many dog owners report positive experiences with NexGard, noting significant reductions in flea and tick infestations and ease of administration.

How Long Does NexGard Last?

Duration of Effectiveness

Each dose of NexGard is effective for one month. Consistent monthly dosing ensures continuous protection against fleas and ticks.

Factors Affecting Longevity

Factors such as your dog’s metabolism, weight, and health status can influence how long NexGard remains effective. Always follow the recommended dosing schedule.

NexGard for Puppies and Older Dogs

Safety and Efficacy in Puppies

NexGard is safe for puppies as young as 8 weeks old and weighing at least 4 pounds. It’s an excellent option for early flea and tick prevention.

Considerations for Senior Dogs

Older dogs can also benefit from NexGard, but it’s essential to consult your vet, especially if your senior dog has any underlying health conditions.

NexGard and Other Medications

Interaction with Other Medications

NexGard can be safely used alongside many other medications. However, always inform your vet about all the medications your dog is taking to avoid potential interactions.

Veterinary Advice on Combining Treatments

Your vet can provide guidance on whether NexGard can be combined with other flea and tick preventatives or medications for optimal protection.

NexGard and Dog Breeds

Any Breed-Specific Considerations

NexGard is suitable for all dog breeds. However, some breeds with a higher incidence of genetic conditions, such as MDR1 gene mutation, may require additional caution.

Working dogs, show dogs, and dogs with specific lifestyle needs can all benefit from NexGard’s convenient and effective protection.
