When it comes to protecting our furry friends from pests, the battle against fleas remains at the forefront of every pet owner’s mind. Two products that frequently come up in conversations are Comfortis and NexGard. But how do they compare, and which one is right for your dog?
What are Comfortis and NexGard?
Comfortis: An oral flea preventative, Comfortis starts working within 30 minutes, eliminating over 98% of fleas in just four hours. Its active ingredient, spinosad, targets adult fleas, ensuring that they can’t reproduce.
NexGard: Not only is NexGard effective against fleas, but it also combats ticks. As a chewable tablet, it disrupts the life cycle of both pests, offering protection for a full month.
Efficacy: Which Works Better?
Both products are extremely effective against fleas. Comfortis has the edge in speed, starting its action in as little as 30 minutes, while NexGard usually takes a few hours. However, both guarantee almost complete elimination of adult fleas within 24 hours.
NexGard has an advantage here, as it’s also a tick preventative. Comfortis does not offer protection against ticks, meaning if ticks are a concern in your area, NexGard might be the better choice.
Side Effects: What to Look Out For
Every medication has the potential for side effects, and these flea preventatives are no exception.
Comfortis: The most common side effect observed is vomiting, especially if the dog hasn’t eaten before taking the tablet. Other side effects might include reduced appetite, lethargy, or diarrhea.
NexGard: Some dogs might experience vomiting, diarrhea, dry or flaky skin, and lethargy. Although rare, more serious side effects can occur, so always monitor your pet after administering a new medication.
Cost: Breaking Down the Price
The price of both medications varies depending on where you purchase them, the size of the pack, and any discounts or promotions. Generally, NexGard tends to be more expensive given its dual-action against fleas and ticks. However, the peace of mind knowing your pet is protected might be worth the extra cost.
Considerations for Specific Breeds
Certain breeds, like Greyhounds, are known for their sensitivities to medications. While both Comfortis and NexGard are considered safe for most breeds, always consult with your veterinarian before making a choice, especially if you own a breed with known sensitivities.
The Final Verdict
Ultimately, the choice between Comfortis and NexGard boils down to your specific needs:
- If you’re looking for a rapid-action, flea-only treatment and are on a tighter budget, Comfortis might be your pick.
- If you want comprehensive protection against both fleas and ticks, and are okay with a slightly higher price tag, NexGard is the way to go.
Either way, always make informed decisions based on your dog’s health, breed, age, and environment. And remember, regular check-ups with your vet are the best way to ensure the well-being of your beloved pet.
FAQs on Comfortis vs. NexGard
1. How do Comfortis and NexGard work?
Comfortis: The active ingredient, spinosad, targets the nervous system of adult fleas, rendering them paralyzed and leading to their eventual death. Since it targets only adult fleas, it prevents them from reproducing.
NexGard: NexGard contains the active ingredient afoxolaner, which interferes with the nervous system of fleas and ticks, causing over-stimulation and eventual death.
2. Can I use Comfortis and NexGard concurrently?
It’s essential to avoid mixing flea and tick medications without consulting your veterinarian. Each medication is designed with specific dosages in mind, and combining them could lead to an overdose or potential negative interactions.

Both Comfortis and NexGard are oral treatments. Administering with food can help decrease the chances of stomach upset and ensure better absorption of the medication.

Comfortis: It’s a monthly treatment, which means you should give your dog a new dose every 30 days.
NexGard: Similarly, NexGard is also administered monthly. Ensure consistent monthly dosing for continued protection.

If your dog exhibits any unusual symptoms or reactions after taking either medication, consult your veterinarian immediately. Monitoring your pet for a few hours post-administration can help detect early signs of discomfort or adverse reactions.
11. How does resistance develop, and are Comfortis or NexGard affected?
Over time, parasites like fleas and ticks can develop resistance to certain treatments due to genetic mutations. However, as of now, there have been minimal reports of resistance towards the active ingredients in both Comfortis and NexGard. Regularly alternating between different classes of preventatives can help delay resistance development.

14. How do environmental factors affect the efficacy of these treatments?
Environmental infestations can impact the perceived effectiveness of these treatments.

Regular cleaning, vacuuming, and treating outdoor areas can augment the efficacy of oral preventatives.

If your dog has existing health issues like liver or kidney problems, or a history of seizures, consult your vet before starting any new medication. They will evaluate the potential risks and benefits, offering alternatives if needed.
