When it comes to protecting our furry friends from fleas and ticks, it’s important to choose the right product. Two popular options on the market are NexGard and Capstar. But how do these products compare? In this article, we will explore the key differences between NexGard and Capstar, helping you make an informed decision for your pet’s health and well-being.

NexGard: The Proven Protector

What is NexGard?

NexGard is a chewable flea and tick treatment for dogs. It contains a powerful active ingredient called afoxolaner, which effectively kills fleas and ticks for up to 30 days. NexGard is available in different dosages based on your dog’s weight, making it suitable for dogs of all sizes.

How Does NexGard Work?

NexGard works by targeting the nervous system of fleas and ticks, causing paralysis and ultimately leading to their death. After your dog ingests the chewable tablet, afoxolaner is absorbed into their bloodstream, providing continuous protection against fleas and ticks.

Benefits of NexGard

  • Long-lasting protection: NexGard provides a full month of protection against fleas and ticks, ensuring your dog stays safe and comfortable.
  • Easy administration: The chewable tablet form of NexGard makes it easy to administer to your dog. Most dogs love the taste, making it a hassle-free experience for both you and your furry friend.
  • Water-resistant: NexGard remains effective even if your dog gets wet or goes swimming. This is particularly beneficial for dogs who love water activities.

Is NexGard Safe?

NexGard has been extensively tested and proven to be safe for dogs. However, it is always recommended to consult with your veterinarian before starting any new flea and tick treatment. They will be able to assess your dog’s individual needs and determine if NexGard is the right choice for them.

Capstar: The Fast-Acting Solution

What is Capstar?

Capstar is a fast-acting oral flea treatment for dogs and cats. It contains an active ingredient called nitenpyram, which starts killing fleas within 30 minutes of administration. Capstar is available in different dosages for dogs and cats, ensuring safe and effective flea control for all your pets.

How Does Capstar Work?

Capstar works by interfering with the nervous system of fleas, leading to their rapid death. Once ingested, nitenpyram is absorbed into the bloodstream, ensuring that fleas are eliminated quickly.

Benefits of Capstar

  • Rapid flea control: Capstar starts killing fleas within 30 minutes, providing immediate relief for your pet. This is particularly useful in situations where your pet is heavily infested with fleas.
  • Suitable for all pets: Capstar is available for both dogs and cats, making it a versatile option for multi-pet households.
  • Safe for pregnant or nursing pets: Capstar is safe to use on pregnant or nursing pets, providing peace of mind for pet owners.

Is Capstar Safe?

Capstar is considered safe for dogs and cats, but it is always important to consult with your veterinarian before using any new flea treatment. They will be able to advise you on the most suitable options based on your pet’s specific needs.

NexGard vs Capstar: Which Should You Choose?

Both NexGard and Capstar have their own unique benefits, so the choice ultimately depends on your pet’s individual needs and preferences. Here are some factors to consider when making your decision:

  1. Duration of protection: NexGard provides continuous protection for a full month, while Capstar’s effects last for 24 hours. If you’re looking for long-lasting flea and tick control, NexGard may be the better option.
  2. Immediate relief: If your pet is suffering from a severe flea infestation and you need immediate relief, Capstar’s fast-acting formula can provide quick results.
  3. Water resistance: If your dog loves water activities, NexGard’s water-resistant formula ensures that they remain protected even after swimming or bathing.
  4. Convenience: NexGard’s chewable tablet form makes it easy to administer, while Capstar’s small pill can be hidden in your pet’s food for hassle-free dosing.

Ultimately, it is always recommended to consult with your veterinarian to determine the best flea and tick control option for your pet’s specific needs.


When it comes to choosing between NexGard and Capstar for flea and tick control, both products have their own unique advantages. NexGard provides long-lasting protection and is water-resistant, while Capstar offers rapid relief for severe infestations. By considering your pet’s specific needs and consulting with your veterinarian, you can make an informed decision that ensures the health and well-being of your furry friend.
