NexGard is a popular flea and tick treatment for dogs that offers effective protection against a range of parasites. This chewable tablet is easy to administer and provides long-lasting defense against fleas and ticks. In this article, we will explore the various parasites that NexGard protects against and why it is an excellent choice for keeping your furry friend safe and healthy.

Fleas: The Pesky Bloodsuckers

Fleas are tiny, wingless insects that feed on the blood of animals, including dogs. These pesky parasites can cause a variety of health issues, including itching, skin infections, and even anemia in severe cases. Fleas are not only irritating for your furry friend but can also infest your home, leading to a full-blown flea infestation.

NexGard is highly effective in killing fleas before they have a chance to lay eggs, preventing infestations from taking hold. The active ingredient in NexGard, afoxolaner, works by targeting the fleas’ nervous system, causing paralysis and ultimately leading to their death. This fast-acting treatment starts killing fleas within hours and provides month-long protection.

Ticks: More Than Just Annoying

Ticks are external parasites that can transmit a range of diseases to both animals and humans. These small arachnids attach themselves to the host and feed on their blood. In the process, they can transmit dangerous pathogens, including Lyme disease, ehrlichiosis, and anaplasmosis.

NexGard is highly effective in killing ticks, preventing them from attaching to your dog and reducing the risk of disease transmission. It works by interfering with the ticks’ nervous system, causing paralysis and death. NexGard provides month-long protection against ticks, ensuring that your furry friend stays safe and healthy.

Sarcoptic Mange: The Itch That Won’t Quit

Sarcoptic mange, also known as scabies, is a highly contagious skin disease caused by the Sarcoptes scabiei mite. This microscopic mite burrows into the skin, causing intense itching, hair loss, and skin infections. Sarcoptic mange can spread rapidly among dogs, making it essential to treat and prevent infestations.

NexGard is effective in treating and preventing sarcoptic mange infestations. The chewable tablet kills the mites responsible for the condition, providing relief from itching and promoting the healing of the skin. Regular use of NexGard can help prevent future infestations and keep your dog comfortable and happy.

Demodectic Mange: A Mite Overload

Demodectic mange, also known as demodicosis, is a skin disease caused by an overgrowth of Demodex mites. These mites are naturally present in small numbers on the skin of dogs, but an overgrowth can lead to hair loss, skin infections, and inflammation. Demodectic mange is more common in puppies and dogs with weakened immune systems.

NexGard can help manage demodectic mange by killing the mites responsible for the condition. Regular use of NexGard can help control the mite population and reduce the symptoms of demodicosis. It is important to note that severe cases of demodectic mange may require additional treatment options, so consulting with a veterinarian is recommended.

Ear Mites: The Unwelcome Guests

Ear mites are tiny parasites that infest the ears of dogs, causing irritation, itching, and inflammation. These mites can multiply rapidly and spread to other pets in the household. Ear mite infestations can be uncomfortable and distressing for your furry friend, leading to ear infections if left untreated.

NexGard is not specifically formulated to target ear mites, but its efficacy against other mites suggests that it may provide some relief from ear mite infestations. However, it is crucial to consult with a veterinarian for an accurate diagnosis and appropriate treatment options for ear mites.

Intestinal Worms: Silent Intruders

Intestinal worms, such as roundworms, hookworms, and whipworms, are common parasites that can infect dogs. These worms can cause a range of health issues, including diarrhea, weight loss, and anemia. Some intestinal worms can also be transmitted to humans, making it essential to keep your furry friend protected.

NexGard does not provide protection against intestinal worms. However, there are other deworming treatments available that can effectively eliminate these parasites. Regular deworming, in combination with NexGard’s flea and tick protection, ensures comprehensive parasite prevention for your dog.


NexGard is a reliable and effective flea and tick treatment that provides comprehensive protection for your furry friend. It kills fleas and ticks, preventing infestations and reducing the risk of disease transmission. NexGard also offers relief from sarcoptic mange and can help manage demodectic mange. While it may provide some relief from ear mites, consulting with a veterinarian is recommended for proper diagnosis and treatment. Remember to combine NexGard with regular deworming to ensure your dog is protected against all parasites.
