FAQs on Nexgard

1. Can Nexgard Affect My Dog’s Behavior or Mood?

While Nexgard primarily targets parasites, it’s natural to wonder about its impact on your dog’s demeanor. Generally, Nexgard does not directly influence behavior or mood. However, the relief from itching and discomfort can lead to a noticeable improvement in your dog’s overall well-being and activity levels. If you observe any drastic behavioral changes post-administration, it’s prudent to consult your veterinarian, as these could stem from other underlying issues.

2. How Does Nexgard Fare in Different Climates?

The efficacy of Nexgard remains consistent across various climates. Whether you’re in a humid tropical region or a dry, cold area, Nexgard’s formula is designed to maintain its potency. However, environmental factors can influence the prevalence of fleas and ticks. For instance, warmer climates might see a higher flea population, necessitating strict adherence to the monthly dosing schedule.

3. Interaction with Other Medications: What Should I Know?

Introducing any new medication to your pet’s regimen warrants a discussion with your vet, especially regarding potential interactions. Nexgard has been tested for compatibility with various common medications and has shown no adverse interactions in most cases. However, if your dog is on a unique medication or has a complex medical history, a vet consultation becomes even more crucial to ensure safe co-administration.

4. Is Nexgard Suitable for Dogs with Sensitive Stomachs?

Dogs with sensitive stomachs often pose a challenge when it comes to oral medications. Nexgard, while generally well-tolerated, can cause gastrointestinal upset in some dogs. If your dog has a history of digestive issues, it’s advisable to administer Nexgard with food and monitor closely. In cases of severe sensitivity, your vet might suggest alternative flea and tick prevention methods.

5. How Does Nexgard Impact the Dog’s Skin and Coat?

Nexgard’s action is internal, targeting the nervous system of fleas and ticks. It does not have a direct effect on the skin and coat. However, by eliminating fleas, which are common causes of allergic dermatitis, Nexgard can indirectly contribute to a healthier skin and coat. It’s important to differentiate between the effects of Nexgard and symptoms of flea allergy dermatitis, which might take time to resolve even after flea elimination.

6. What Happens if a Dose is Missed or Delayed?

Consistency is key with Nexgard. A missed or delayed dose can leave your dog vulnerable to flea and tick infestations. If a dose is missed, administer it as soon as you remember and resume the monthly schedule. Do not double dose to compensate for the missed one. If you’re frequently missing doses, setting reminders or discussing alternative treatments with your vet might be beneficial.

7. Can Nexgard be Used in Conjunction with Other Flea and Tick Preventatives?

Using multiple flea and tick preventatives simultaneously is generally not recommended unless specifically advised by your vet. This approach can increase the risk of overmedication and potential side effects. If you’re considering additional preventatives, perhaps due to a severe infestation, consult your vet for the safest course of action.

8. How Long After Bathing My Dog Can I Administer Nexgard?

Nexgard can be administered regardless of your dog’s bathing schedule. Its efficacy is not affected by bathing or swimming, as it is absorbed internally and not dependent on skin and coat conditions. However, for optimal absorption, it’s advisable to administer Nexgard on a dry coat, ensuring that the dog’s skin is not overly hydrated from recent bathing.

9. Nexgard’s Role in Managing Flea Allergy Dermatitis (FAD)

Flea Allergy Dermatitis, a common ailment in dogs, is often exacerbated by flea bites. Nexgard, by eliminating fleas rapidly, plays a significant role in managing FAD. It reduces the potential for flea bites, thereby minimizing the allergic reactions. However, it’s crucial to understand that while Nexgard tackles the cause (fleas), additional treatment may be necessary for the allergic symptoms, which a veterinarian should supervise.

10. Duration of Nexgard’s Effectiveness in Water-Loving Dogs

For dogs that love swimming or require frequent baths, the effectiveness of Nexgard remains a concern for many pet owners. Fortunately, Nexgard’s performance is not compromised by water exposure. Its active ingredient, afoxolaner, is absorbed into the bloodstream, making it resistant to washing off. This feature ensures that water-loving dogs remain protected without the need for more frequent dosing.

11. The Safety of Nexgard for Pregnant or Nursing Dogs

The use of Nexgard in pregnant or nursing dogs is a topic that requires careful consideration. While studies have shown Nexgard to be safe in these cases, it’s always advisable to consult with a veterinarian. The vet can weigh the benefits against any potential risks, ensuring the health and safety of both the mother and her offspring.

12. Nexgard’s Effectiveness Against Different Tick Species

Nexgard is formulated to be effective against a variety of tick species, which is vital given the diverse tick populations across different regions. While it’s highly effective against common species like the American Dog Tick and the Black-legged Tick, its efficacy can vary slightly with different species. Regular checks for ticks, even when using Nexgard, are recommended, especially in areas with high tick prevalence.

13. Handling Potential Side Effects of Nexgard

While Nexgard is generally well-tolerated, side effects can occur in some dogs. These may include gastrointestinal upset, lethargy, or skin reactions. If you notice any adverse effects, it’s important to contact your veterinarian immediately. They can provide guidance on managing these symptoms and decide whether to continue with Nexgard or consider alternative treatments.

14. The Impact of Nexgard on Young Puppies

Nexgard is approved for use in puppies 8 weeks of age and older, weighing at least 4 pounds. For young puppies, it’s essential to adhere to these guidelines to ensure safety. The puppy’s developing system can handle the medication effectively from this age, providing them with the necessary protection against fleas and ticks without undue risk.

15. Combining Nexgard with Natural Flea and Tick Repellents

Some pet owners are interested in combining Nexgard with natural repellents for added protection. While Nexgard is sufficient for flea and tick control, adding natural repellents like certain essential oils or diatomaceous earth can be considered. However, it’s important to consult with a veterinarian before combining treatments, as some natural products might irritate your dog’s skin or interfere with Nexgard’s efficacy.

16. Nexgard’s Storage and Shelf Life Considerations

Proper storage of Nexgard is essential for maintaining its effectiveness. It should be stored at room temperature, away from direct sunlight and moisture. The shelf life of Nexgard, as indicated on its packaging, should be adhered to. Using expired Nexgard can reduce its effectiveness and may not provide the full protective benefit against fleas and ticks.
