When it comes to protecting our furry friends from fleas and ticks, choosing the right product is crucial. Two popular options in the market are NexGard and NexGard Spectra. Both are oral chewables that provide effective protection against parasites. In this article, we will delve into the similarities and differences between these two products to help you make an informed decision for your pet’s health and well-being.

What is NexGard?

NexGard is a renowned flea and tick treatment designed specifically for dogs. It is a monthly oral chewable that contains a powerful active ingredient called afoxolaner. This ingredient works by targeting and killing fleas and ticks upon contact, preventing infestation and providing immediate relief to your furry companion. NexGard is highly effective against the most common species of fleas and ticks, including the hard-to-kill paralysis tick.

What is NexGard Spectra?

NexGard Spectra, on the other hand, is a broad-spectrum parasite preventive that offers protection against fleas, ticks, heartworm, and intestinal worms. It contains two active ingredients: afoxolaner, which targets fleas and ticks, and milbemycin oxime, which protects against heartworm and controls intestinal worms. NexGard Spectra provides comprehensive protection in a single monthly chewable, offering convenience and peace of mind.

Key Similarities between NexGard and NexGard Spectra

Both NexGard and NexGard Spectra share several similarities, making them popular choices among pet owners. Here are some key similarities between the two products:

1. Oral Chewables

Both NexGard and NexGard Spectra come in the form of oral chewables. This makes administration easy and convenient, as you can simply give it to your dog as a treat or mix it with their food. There’s no need to worry about messy topical applications or the product washing off.

2. Monthly Protection

Both products provide monthly protection, ensuring that your dog remains safeguarded against fleas, ticks, and other parasites throughout the month. This regular dosing schedule helps to maintain a consistent level of protection and prevent infestations.

3. Fast-Acting

Both NexGard and NexGard Spectra start working quickly to kill fleas and ticks. NexGard eliminates fleas within 8 hours and ticks within 48 hours of administration, while NexGard Spectra provides rapid action against fleas and ticks within 6 hours.

4. Suitable for Different Breeds

Both products are suitable for use in various dog breeds, including small, medium, and large dogs. However, it is always advisable to consult with your veterinarian to determine the appropriate dosage based on your dog’s weight and health condition.

Key Differences between NexGard and NexGard Spectra

While NexGard and NexGard Spectra share similarities, there are also some notable differences between the two products. Understanding these differences can help you choose the most suitable option for your dog’s specific needs. Let’s explore the key differences:

1. Parasite Coverage

One of the significant differences between NexGard and NexGard Spectra is the range of parasites they protect against. NexGard primarily targets fleas and ticks, whereas NexGard Spectra provides broader coverage by also protecting against heartworm and intestinal worms.

2. Heartworm Prevention

NexGard Spectra is the only product among the two that offers protection against heartworm disease. Heartworms are transmitted through mosquito bites and can cause severe health issues in dogs. NexGard Spectra’s inclusion of milbemycin oxime ensures comprehensive heartworm prevention, which is particularly important in regions where heartworm is prevalent.

3. Intestinal Worm Control

Another significant difference is the control of intestinal worms. NexGard Spectra contains milbemycin oxime, which targets and controls common intestinal worms such as roundworms, hookworms, and whipworms. This added protection is especially beneficial for dogs that may be at risk of contracting these worms.

4. Price

Due to its broader spectrum of protection, NexGard Spectra is generally priced slightly higher than NexGard. However, the added benefits and convenience it offers may outweigh the price difference for pet owners seeking comprehensive parasite prevention.


Choosing between NexGard and NexGard Spectra ultimately depends on your dog’s specific needs and the level of protection you desire. If you are primarily concerned about fleas and ticks, NexGard may be a suitable choice. However, if you want comprehensive protection against fleas, ticks, heartworm, and intestinal worms, NexGard Spectra is the ideal option. Consult with your veterinarian to determine the best choice for your furry friend and ensure their health and well-being.
