Does NexGard Protect Against Heartworm?
NexGard has cemented its place in the pet care industry as a leading flea and tick preventive. With so many pet owners transitioning to oral preventives for their furry friends, the question that frequently arises is: Does NexGard also protect against heartworm?
1. NexGard vs. NexGard Spectra: Know the Difference
The first and foremost thing to understand is the distinction between NexGard and NexGard Spectra. While both are products from the same brand, they cater to different needs.
- NexGard: Primarily designed for the treatment and prevention of flea and tick infestations in dogs.
- NexGard Spectra: A more comprehensive solution, this protects against fleas, ticks, heartworm, lungworm, hookworm, whipworm, and other intestinal parasites.
2. The Heartworm Threat: Why Prevention is Crucial
Heartworms are parasites transmitted through the bite of an infected mosquito. Once a dog is bitten, these worms mature and can eventually occupy the heart and lungs, leading to severe complications and even death. With no vaccine available for heartworm disease, prevention remains the primary defense mechanism for our pets.
3. How NexGard Spectra Fights Off Heartworm
Unlike the standard NexGard, NexGard Spectra contains an ingredient that works against heartworm larvae, ensuring they don’t mature into adult worms. Given monthly, it ensures consistent protection, preventing any chances of infestation.
4. Considering Combined Treatments
Some vets recommend a combination of treatments for complete protection. For instance, while NexGard takes care of fleas and ticks, another medication like Heartgard can be administered for heartworm prevention. Always consult with your veterinarian to decide on the best combination and dosage for your pet.
5. Side Effects and Considerations
As with any medication, it’s essential to be aware of potential side effects. While most dogs tolerate NexGard Spectra well, some might experience digestive issues, lethargy, or itching. Always monitor your pet after administering any new medication and report any unusual behavior to your vet.
6. NexGard Spectra: The All-in-One Solution?
While NexGard Spectra does offer broader protection compared to its counterpart, it’s vital to understand what it does not cover. For example, certain specific parasites or conditions might require specialized treatment. Discussing your dog’s lifestyle, environment, and potential exposure risks with a veterinarian will help tailor the best protection plan.
7. Final Takeaway
NexGard Spectra, with its dual protection against external and internal parasites, offers an effective solution for those looking to consolidate their pet’s preventive regimen. However, always keep an open dialogue with your vet, ensuring that your beloved four-legged friend receives the comprehensive care they deserve.
FAQs about NexGard and Heartworm Protection
1. What is the active ingredient in NexGard Spectra that combats heartworm?
The active ingredient responsible for offering protection against heartworm in NexGard Spectra is moxidectin. This compound specifically targets the heartworm larvae, preventing them from maturing into harmful adult worms.
2. Can I give NexGard and NexGard Spectra simultaneously?
It’s not advisable to administer both products simultaneously as NexGard Spectra already contains the benefits of NexGard with added protection against more parasites. Double dosing can lead to potential overdose and increased risk of side effects. Always consult your vet before making decisions on medication combinations.
3. How long after administering NexGard Spectra does protection begin?
For fleas and ticks, protection begins within hours. However, for heartworm and other internal parasites, the protection is more about disrupting the lifecycle, which requires consistent monthly dosing to ensure that any larvae ingested by the dog during the month are rendered harmless.
4. Are there breeds that are particularly sensitive to NexGard Spectra?
While NexGard Spectra is generally safe for all breeds, some dogs might exhibit sensitivity, particularly those with a history of seizures. Always start with the recommended dosage and monitor your pet closely, especially the first time they receive any new medication.
5. Can puppies take NexGard Spectra?
Yes, NexGard Spectra is suitable for puppies, but there are age and weight restrictions. Puppies should be at least 8 weeks old and weigh more than 4.4 pounds. As with all medications, it’s essential to consult your vet for the right dosage and administration frequency.
6. Does NexGard Spectra also protect against other types of worms besides heartworm?
Absolutely! Apart from heartworm, NexGard Spectra provides protection against lungworm, hookworm, and whipworm, ensuring comprehensive internal parasitic control.
7. How does NexGard Spectra compare with other combination treatments like Simparica Trio or Heartgard?
Each of these products has its unique formulation and spectrum of protection. While NexGard Spectra covers a broad range of parasites, Simparica Trio and Heartgard might focus on specific combinations. It’s always best to discuss with your vet about regional parasite prevalence and your dog’s specific needs to choose the right product.
8. Is there a recommended time of year to start NexGard Spectra for heartworm prevention?
Heartworm prevention should be a year-round commitment, irrespective of the season. While mosquitoes, the primary carriers of heartworm, are more prevalent in warmer months, they can be found year-round in many regions. Continuous protection ensures no gaps and optimal health for your pet.
9. What should I do if I miss a dose?
If you miss a dose, administer NexGard Spectra as soon as you remember. It’s essential to get back on track with monthly dosing and consult your vet if multiple doses are missed, as this might expose your dog to potential risks.

While no specific drug interactions have been identified, always inform your veterinarian about any other medications, supplements, or treatments your dog is receiving. This ensures a holistic approach to your pet’s healthcare and avoids any potential adverse reactions.
11. How does NexGard Spectra’s efficacy compare over time?
The effectiveness of NexGard Spectra remains consistent when administered monthly. Like many other preventatives, its potency is designed to last the full 30 days. However, skipping or delaying doses can compromise its efficacy, potentially exposing your dog to parasites.
12. Can NexGard Spectra be administered to pregnant or lactating dogs?
Currently, there haven’t been adequate studies on the effects of NexGard Spectra on pregnant or lactating dogs. It’s crucial to consult with your veterinarian before administering any medication to such dogs, as they may have specific needs or vulnerabilities.
13. Are there common side effects associated with NexGard Spectra?

Typically, the expiration date is printed on the packaging. It’s recommended to use the product before this date to ensure its full efficacy. Store in a cool, dry place, away from direct sunlight to maintain its potency.
15. Is it safe to touch or handle the NexGard Spectra chewable after breaking it from its packaging?
Yes, NexGard Spectra is safe to handle. However, always ensure you wash your hands after administration, especially before handling food. Keeping the medication out of children’s reach is also crucial.
16. How does NexGard Spectra differ from topical flea and tick treatments?
NexGard Spectra is an oral medication, eliminating the potential mess or concern about washing off that comes with topical treatments. Being ingested, it circulates in the dog’s bloodstream, killing parasites upon biting, rather than on contact. This method can be more convenient for pet owners who bathe their dogs frequently or whose pets are often in water.
17. What precautions should be taken when starting NexGard Spectra for a dog with a history of allergies?
For dogs with known allergies, it’s essential to introduce any new medication with caution. While allergic reactions to NexGard Spectra are rare, it’s best to monitor your dog closely during the initial doses. Any signs of hives, difficulty breathing, or swelling should be addressed immediately with your veterinarian.
18. How does NexGard Spectra impact the environment, considering its elimination through feces?
All medications, including NexGard Spectra, are metabolized and excreted, which can end up in the environment. Currently, there’s no strong evidence suggesting significant environmental harm from NexGard Spectra. Still, it’s always a good practice to pick up after your dog and dispose of feces appropriately.
19. Can NexGard Spectra be given with food?
Yes, NexGard Spectra can be given with or without food. Some pet owners find it easier to administer the chewable by mixing it with their dog’s meal.
20. What steps should I take if I suspect an overdose of NexGard Spectra?
If an overdose is suspected, it’s essential to contact your vet or an emergency animal clinic immediately. Symptoms might include increased salivation, vomiting, or increased pacing. Early intervention can help manage any potential adverse effects.
21. How does NexGard Spectra interact with other medications?
While NexGard Spectra is typically safe to use alongside many common canine medications, interactions can occur. Before starting your dog on NexGard Spectra, provide your vet with a comprehensive list of any current medications or supplements your pet is taking.
22. Can puppies be given NexGard Spectra?
NexGard Spectra is suitable for puppies, but there are age and weight guidelines. Typically, it can be given to puppies from 8 weeks of age and weighing at least 4 pounds. Always check the product label or consult your vet for age and weight restrictions.
23. If my dog has had adverse reactions to other flea treatments, is NexGard Spectra a safer alternative?
Every dog reacts differently to medications. While some dogs that experienced negative side effects with other treatments tolerate NexGard Spectra well, it’s not guaranteed. A gradual introduction and close monitoring are advised when switching flea treatments.
24. How does NexGard Spectra work at a molecular level?
NexGard Spectra contains the active ingredients afoxolaner and milbemycin oxime. Afoxolaner targets the nervous system of fleas and ticks, leading to overstimulation and eventual death. Milbemycin oxime affects the neurological system of heartworms and intestinal parasites, disrupting their life cycle and eliminating them.
25. Can I split a NexGard Spectra chewable between two dogs?
It’s not advisable to split the chewable. The distribution of active ingredients may not be even throughout the chewable, potentially leading to under-dosing or overdosing. Always administer the appropriate size and dosage for each individual dog’s weight.
26. What happens if my dog vomits shortly after taking NexGard Spectra?
If your dog vomits within a few hours of taking the medication, it might not have been fully absorbed. It’s best to consult your veterinarian on whether to administer another dose or wait until the next scheduled dose.
27. Does NexGard Spectra protect against tapeworms?
While NexGard Spectra covers a broad spectrum of parasites, it does not specifically target tapeworms. If tapeworm prevention or treatment is a concern, discuss additional or alternative treatments with your vet.
28. How long should I wait to bathe my dog after giving NexGard Spectra?
As NexGard Spectra is an oral treatment, there are no restrictions regarding bathing or swimming. The treatment won’t wash off, and its efficacy won’t be diminished by water exposure.
29. Can NexGard Spectra cause resistance in parasites over time?
Resistance is a concern with any anti-parasitic medication. However, the combination of active ingredients in NexGard Spectra and its mode of action reduce the risk of resistance development. Still, rotating treatments under a vet’s guidance can further mitigate potential resistance.
30. How is NexGard Spectra different from generic alternatives?
NexGard Spectra has undergone extensive testing to ensure its safety and efficacy. While generic alternatives may contain similar active ingredients, their formulation, absorption rate, and other inactive ingredients can vary. It’s essential to consult your vet about the suitability and reliability of any generic alternatives.
