💬 What’s the Difference Between NexGard and NexGard Spectra?

Although they share a similar name, NexGard and NexGard Spectra have key differences in the range of protection they offer. Let’s break it down:

ProductParasites CoveredFrequency of Use💡 Tip
NexGardFleas, TicksMonthlyGreat for pets that only need external parasite protection.
NexGard SpectraFleas, Ticks, Heartworms, Roundworms, HookwormsMonthlyIdeal for all-around protection against both internal and external parasites.

💡 Pro Tip: If your dog is only at risk of fleas and ticks, NexGard may be the simplest solution. However, if you want comprehensive protection that includes worms, NexGard Spectra is the better option.


🧴 How Does Drontal Compare to NexGard and NexGard Spectra?

Drontal is not an anti-flea or anti-tick medication, but rather a broad-spectrum dewormer that targets intestinal worms such as roundworms, tapeworms, and hookworms. It’s often used in conjunction with flea and tick preventatives like NexGard or NexGard Spectra.

ProductParasites CoveredFrequency of Use💡 Tip
DrontalRoundworms, Hookworms, TapewormsEvery 3 monthsUse Drontal alongside flea/tick treatments for full parasite control.
NexGardFleas, TicksMonthlyCombine with Drontal for internal parasite protection.
NexGard SpectraFleas, Ticks, Heartworms, Roundworms, HookwormsMonthlyProvides all-in-one coverage for internal and external parasites.

💡 Pro Tip: If your dog doesn’t require heartworm prevention but needs deworming, Drontal combined with NexGard is an effective approach. For all-in-one protection, consider NexGard Spectra.


🐕‍🦺 Which Product Offers the Best Flea and Tick Protection?

Both NexGard and NexGard Spectra are highly effective against fleas and ticks. They work by killing parasites before they have a chance to reproduce or cause disease. However, Drontal does not protect against external parasites like fleas or ticks.

ProductFlea and Tick ProtectionSpeed of Action💡 Tip
NexGardYes – Kills fleas within 4 hours, ticks within 48 hoursFast actingIdeal for dogs that regularly encounter fleas and ticks.
NexGard SpectraYes – Same flea and tick protection as NexGardFast actingBest for dogs who need additional worm protection alongside flea/tick control.
DrontalNo flea/tick protectionN/ANot designed for flea or tick prevention.

💡 Pro Tip: If fleas and ticks are your primary concern, NexGard is highly effective. For all-in-one parasite protection, go with NexGard Spectra to handle internal and external threats.


🌱 Which Product is More Convenient to Use?

When it comes to convenience, NexGard Spectra stands out as it covers both external (fleas, ticks) and internal parasites (worms) with just one chewable tablet. Drontal, on the other hand, is typically given every three months and only handles internal parasites, so it needs to be combined with another product like NexGard for complete protection.

ProductFormParasites Covered💡 Tip
NexGardChewable TabletFleas, TicksMonthly dose is easy to administer with food.
NexGard SpectraChewable TabletFleas, Ticks, WormsOne chewable covers everything—ideal for busy pet owners.
DrontalTabletWorms (roundworms, tapeworms, hookworms)Use every 3 months for worm control, but pair with flea/tick prevention.

💡 Pro Tip: If you’re looking for a one-and-done solution to manage all parasites, NexGard Spectra is the most convenient. For more targeted internal worm treatment, Drontal paired with NexGard is effective but requires multiple products.


🐾 Is NexGard Spectra Safe for All Dogs?

Yes, NexGard Spectra is generally considered safe for dogs, but as with any medication, there are specific guidelines to follow. NexGard Spectra is safe for use in puppies over 8 weeks of age and weighing more than 4 pounds. However, if your dog has a history of seizures or neurological issues, you should consult your vet before starting NexGard or NexGard Spectra, as afoxolaner, the active ingredient, can sometimes exacerbate these conditions.

Similarly, Drontal is safe for most dogs, but it is important to dose correctly based on your dog’s weight. Drontal is also safe for pregnant and lactating dogs, which may be a consideration for breeders.

ProductAge RequirementSafety Notes
NexGard8 weeks and older, 4 lbs+Safe for most dogs, but consult your vet if your dog has seizures.
NexGard Spectra8 weeks and older, 4 lbs+Use with caution in dogs with neurological conditions.
Drontal2 weeks and olderSafe for pregnant and lactating dogs.

💡 Pro Tip: Always consult your vet before starting a new medication, especially if your dog has underlying health conditions like epilepsy. For general use, NexGard Spectra is a well-tolerated and comprehensive option for most dogs.

🗝️ Key Takeaways for NexGard, Drontal, and NexGard Spectra:

  • NexGard is excellent for flea and tick prevention but does not protect against worms.
  • NexGard Spectra covers both fleas, ticks, and internal parasites, making it the most comprehensive solution.
  • Drontal is a reliable dewormer, but it requires a separate flea/tick treatment, such as NexGard, for full parasite protection.
  • For ultimate convenience and all-around protection, NexGard Spectra is the best one-stop option, while combining Drontal and NexGard can offer flexibility based on your pet’s needs.

When deciding between NexGard, Drontal, and NexGard Spectra, it’s important to consider the specific parasite risks your dog faces. Whether you need full coverage or targeted treatment, these options ensure your dog stays protected from harmful parasites year-round. 🐾


Comment: “Can I give NexGard and Drontal together, or should I choose NexGard Spectra instead?”

Yes, you can safely give NexGard and Drontal together, and many pet owners do this to cover both external (fleas and ticks) and internal parasites (worms). NexGard provides excellent protection against fleas and ticks, while Drontal is a broad-spectrum dewormer that targets roundworms, tapeworms, and hookworms. Combining the two allows you to address both types of parasites effectively.

However, if you’re looking for convenience, NexGard Spectra is a more streamlined option. It offers all-in-one protection by covering both external parasites (like fleas and ticks) and internal parasites (like heartworms, roundworms, and hookworms). With NexGard Spectra, you only need to administer one chewable tablet monthly, which can simplify your routine.

That being said, there are situations where using NexGard and Drontal separately might be preferable:

  • If your dog doesn’t require heartworm protection, you can use NexGard with Drontal instead of opting for NexGard Spectra, which covers heartworm.
  • Some pet owners prefer using a specific dewormer, like Drontal, if they need to target certain types of worms that may not be as effectively managed by general products.

💡 Pro Tip: If you’re looking for simplicity and comprehensive coverage, NexGard Spectra is the easiest solution. However, for dogs that may not need full parasite protection (e.g., no heartworm risk), using NexGard and Drontal together provides flexibility and effective parasite control.


Comment: “Does NexGard Spectra protect against tapeworms like Drontal does?”

No, NexGard Spectra does not specifically protect against tapeworms. While it covers a broad spectrum of parasites, including fleas, ticks, heartworms, roundworms, and hookworms, it does not target tapeworms, which is where Drontal shines. Drontal is a powerful dewormer that is particularly effective at treating tapeworm infestations in dogs.

Tapeworms are often contracted when a dog ingests fleas carrying the tapeworm larvae, so regular flea control (like NexGard or NexGard Spectra) can help reduce the risk of tapeworm infection. However, if your dog has been diagnosed with tapeworms, you’ll need a specific treatment like Drontal or another tapeworm dewormer to eliminate the problem.

💡 Pro Tip: While NexGard Spectra provides comprehensive protection against most parasites, you’ll need to supplement with Drontal or another tapeworm-specific dewormer if your dog is at risk or shows signs of tapeworms.


Comment: “Can I switch from NexGard to NexGard Spectra if my dog needs worm protection?”

Yes, switching from NexGard to NexGard Spectra is a seamless transition if your dog now requires protection against worms in addition to fleas and ticks. Both products are part of the same family (manufactured by Boehringer Ingelheim) and use the same active ingredient, afoxolaner, for flea and tick protection. The main difference is that NexGard Spectra adds milbemycin oxime, which targets heartworms, roundworms, and hookworms.

When switching to NexGard Spectra, your dog will benefit from the same monthly dosage schedule, but with the added advantage of internal parasite control. It’s an excellent option for dogs that:

  • Are exposed to areas with high heartworm risk.
  • Need roundworm or hookworm protection.
  • Require a more comprehensive parasite prevention routine.

💡 Pro Tip: If your dog’s parasite risk profile changes—such as moving to an area with heartworm risk or being exposed to contaminated soil—it makes sense to switch to NexGard Spectra for broader protection. Consult with your vet to ensure the switch aligns with your dog’s health needs.


Comment: “How do I know if my dog needs NexGard Spectra instead of regular NexGard?”

Determining whether your dog needs NexGard Spectra instead of regular NexGard depends on the type of parasites your dog is exposed to. Here are a few factors to consider when deciding:

  1. Heartworm Risk: If you live in an area where mosquitoes are prevalent, your dog is at higher risk for heartworm disease, which is spread through mosquito bites. NexGard Spectra includes milbemycin oxime to protect against heartworm, while regular NexGard does not.
  2. Intestinal Worm Exposure: Dogs that are regularly exposed to environments where roundworms or hookworms are common—such as parks, trails, or areas with a lot of other animals—will benefit from NexGard Spectra’s internal parasite protection. If your dog spends a lot of time outdoors or is around other animals, NexGard Spectra is a better choice.
  3. Simplified Treatment: If you prefer to streamline your dog’s parasite prevention routine by using just one product for fleas, ticks, heartworms, and intestinal worms, NexGard Spectra is the more convenient solution. With regular NexGard, you’d need to pair it with a separate dewormer like Drontal or a heartworm preventative.
  4. Veterinary Advice: Always consult your vet if you’re unsure whether to use NexGard or NexGard Spectra. They can assess your dog’s lifestyle and exposure risks to help determine the most appropriate protection plan.

💡 Pro Tip: If your dog only needs flea and tick protection, regular NexGard is sufficient. However, if they’re at risk for heartworms or intestinal worms, switching to NexGard Spectra provides comprehensive coverage in one easy monthly dose.


Comment: “Does NexGard Spectra have more side effects compared to regular NexGard?”

Both NexGard and NexGard Spectra are generally well-tolerated, but some dogs may experience mild side effects with either product. Since both use the same active ingredient for flea and tick control (afoxolaner), their safety profiles are similar. The addition of milbemycin oxime in NexGard Spectra (to protect against heartworms and intestinal worms) doesn’t significantly increase the risk of side effects, though there are some important things to keep in mind:

  • Mild Reactions: Common side effects for both NexGard and NexGard Spectra may include vomiting, diarrhea, lethargy, or loss of appetite. These reactions are typically mild and temporary.
  • Neurological Side Effects: In rare cases, both products can cause neurological issues, such as tremors or seizures, particularly in dogs with a history of epilepsy or other neurological conditions. If your dog has experienced seizures in the past, it’s important to consult your vet before using either product.
  • Allergic Reactions: While rare, some dogs may have an allergic reaction to the ingredients in these medications. Signs of an allergic reaction can include swelling, difficulty breathing, or hives. If you notice any severe reactions, contact your vet immediately.

Overall, the side effect profile of NexGard Spectra is very similar to regular NexGard, and both are considered safe for the vast majority of dogs. However, as with any medication, it’s always best to monitor your dog after administering a new treatment, especially for the first time.

💡 Pro Tip: If your dog has had no adverse reactions to regular NexGard, they’re likely to tolerate NexGard Spectra well too. Always consult your vet if you have concerns about side effects, especially if your dog has pre-existing health conditions like seizures.


Comment: “How long does it take for NexGard Spectra to start working?”

NexGard Spectra begins working quickly, typically killing fleas within 4-8 hours and ticks within 24-48 hours after administration. The active ingredient, afoxolaner, is absorbed into your dog’s bloodstream, where it begins to target and kill fleas and ticks as soon as they bite. The milbemycin oxime in NexGard Spectra also starts working quickly to protect against heartworms and intestinal worms.

  • Fleas: NexGard Spectra kills fleas before they can lay eggs, breaking the flea life cycle and preventing infestations.
  • Ticks: Ticks are killed within 48 hours, preventing them from transmitting diseases like Lyme disease.
  • Worms: Milbemycin oxime in NexGard Spectra starts working right away to protect against heartworms, roundworms, and hookworms.

The protection from NexGard Spectra lasts for a full 30 days, meaning it needs to be administered monthly for continuous protection.

💡 Pro Tip: To get the best results, administer NexGard Spectra on the same day each month to maintain consistent protection. It’s fast-acting and provides broad-spectrum parasite control, making it ideal for dogs at risk of fleas, ticks, and worms.
