Nexgard emerges as a potent solution in this battle against pervasive pests. This article explores Nexgard’s specifics, benefits, and why it’s a preferred choice for many pet owners, whether tackling existing infestations or preventing future ones.

Understanding Fleas and Ticks

Fleas and ticks are bothersome parasites causing health problems for both pets and humans. Knowing their lifecycles is crucial for effective prevention and control.

Flea Lifecycle:

    • Egg: Laid by adult female fleas after a blood meal, falling into the environment.
    • Larva: Hatching from eggs, larvae feed on organic debris.
    • Pupa: Larvae transform into adult fleas in a cocoon stage.
    • Adult: Emerges from the cocoon, seeking a blood meal to reproduce.

Tick Lifecycle:

    • Egg: Females lay thousands of eggs in brushy areas.
    • Larva: Hatch, climb onto vegetation, and wait for a host.
    • Nymph: Develop from larvae after feeding.
    • Adult: Latch onto a host for a final blood meal before reproducing.

life cycle of tick

Fleas and ticks carry various diseases that can harm dogs. Lyme disease, transmitted by ticks, is the most common tick-borne illness in the US, causing joint issues and lethargy in dogs. Ehrlichiosis, also from ticks, destroys white blood cells, leading to symptoms like weight loss and anemia. Anaplasmosis, carried by deer ticks, causes fever and joint pain in dogs. Recognizing signs of infestation, like excessive scratching or hair loss, is crucial for your dog’s health.

Why do Pet Parents choose Nexgard for flea and tick prevention?

Nexgard is a popular flea and tick prevention for dogs. Its active ingredient, afoxolaner, is a powerful insecticide that targets the nervous system of fleas and ticks.

Here’s how it works:

    • Blocks Nerve Signals: Afoxolaner blocks specific receptors in the nervous systems of fleas and ticks. These receptors are essential for sending and receiving signals between nerves.
    • Overexcitation and Paralysis: By blocking these receptors, afoxolaner causes uncontrolled nerve activity in fleas and ticks. This overstimulation leads to paralysis and ultimately death.
    • Fast-Acting and Effective: Nexgard starts killing fleas within hours and provides a full month of protection. It’s safe for most dogs over 8 weeks old and weighing more than 4 pounds.

Key Points Simplified

    • Nexgard specifically disrupts the nervous systems of fleas and ticks.
    • This disruption causes paralysis and death, protecting your dog.
    • Nexgard is fast-acting, long-lasting, and generally safe for dogs.

Flea and tick prevention is a critical aspect of pet care, and there are several methods available to protect your dog from these pests:

Prevention Method Description Effectiveness Duration
Nexgard A popular flea and tick preventative for dogs, contains the active ingredient afoxolaner High effect because Nexgard starts killing existing fleas within hours of administration and continues to protect against reinfestation About 1 month
Topical Treatments Liquids applied directly to the dog’s skin. They contain active ingredients that kill fleas and ticks on contact or disrupt their life cycle Topical treatments like K9 Advantix II and Vectra 3D can prevent ticks and fleas from attaching. Products containing fipronil (like Frontline) do not prevent ticks and fleas from attaching, meaning you may still see ticks and fleas crawling on your pet. They will not kill ticks and fleas until after they have attached for 24 hours About 1 month
Collars Worn around the dog’s neck and release insecticides that kill or repel pests Moderate to High effect but the effectiveness can be reduced if the dog is frequently in water. Up to 8 months
Diatomaceous Earth A natural powder made from tiny fossilized aquatic organisms. It’s non-toxic and safe to use around pets. It works by dehydrating fleas and ticks upon contact. Moderate effect but it can vary based on the thoroughness of application Needs to be reapplied after cleaning or rain.
Essential Oils Certain essential oils, like lavender and lemongrass, are known to repel fleas and ticks. They can be diluted and applied to the dog’s coat. Effectiveness can depend on the type of oil used and the concentration. Reapplication is often necessary, especially after bathing
Apple Cider Vinegar A natural repellent that can be sprayed onto the dog’s coat. It’s believed to make the dog’s skin more acidic, thus unappealing to fleas and ticks. Low to moderate effect because it can vary based on the dog’s pH balance. Reapplication is necessary after bathing or swimming.

Clinical studies confirm Nexgard’s efficacy:

A multi-center trial assessed Nexgard’s ability to treat generalized demodicosis in dogs across France, Italy, and Poland. Results revealed a remarkable 98.1% reduction in mite counts and improved skin lesions by Day 84, showcasing its potent acaricidal properties.

Nexgard PLUS, approved by the FDA, offers broad-spectrum protection against fleas, ticks, heartworm disease, roundworms, and hookworms. This beef-flavored soft chew ensures convenient and reliable parasite prevention for pet owners.

Moreover, Nexgard decreases transmission rates of D. immitis and L. infantum, prevalent dog parasites. Post-treatment incidences were reduced to 3.7% and 3.6%, respectively, enhancing its efficacy against these diseases. With a 94.2% and 64% protective efficacy, Nexgard provides comprehensive coverage against canine parasitic diseases.

How to use Nexgard? 

Administering Nexgard to your dog effectively involves understanding the correct dosage and methods to ensure your pet takes the medication willingly. Nexgard’s dosage is based on your dog’s weight:

Dog’s Weight Range Nexgard Dosage (by box color) Active Ingredient Dosage
4 – 10 lbs (2 – 4 kg) Orange Box 11.3 mg of afoxolaner
10.1 – 24 lbs (4.1 – 10 kg) Blue Box 28.3 mg of afoxolaner
24.1 – 60 lbs (10.1 – 25 kg) Green Box 68 mg of afoxolaner
60.1 – 121 lbs (25.1 – 50 kg) Purple Box 136 mg of afoxolaner

Nexgard’s chewable format can be given like a treat, avoiding the issue of wash-off with topical treatments. Continuous monthly administration throughout the year ensures ongoing protection.


For dogs hesitant about medication, disguising the tablet in a treat, such as cheese or peanut butter, can be effective. Making medication a game by interspersing the medicated treat among plain ones can help, as can maintaining a calm demeanor. Always praise or reward your dog post-medication to foster positive associations.

While Nexgard is known to be safe and effective, it can have side effects including vomiting, itching, lethargy, diarrhea, and loss of appetite, with less common issues like dry skin, neurological problems, or allergic reactions. Its safety for breeding, pregnant, or lactating dogs has not been determined. If adverse reactions occur, discontinue Nexgard immediately, especially in the case of severe symptoms like allergic reactions or loss of consciousness.

Additional Preventative Measures

When it comes to using Nexgard, a leading product in flea and tick prevention, it’s essential to understand the comprehensive approach needed to ensure your dog’s environment is as inhospitable to these pests as possible.

Additional Preventative Measures Details
Manage Environment Regularly clean your dog’s living areas, including their bed, toys, and feeding bowls. Use non-toxic flea sprays or powders for added protection. Vacuum your home frequently, especially in areas where your dog spends a lot of time. Fleas can live in carpets and furniture.
Groom Regularly Use a fine-toothed flea comb to check your dog’s coat, especially around the ears, under the collar, and the base of the tail.
Limit Outdoor Time Limit the amount of time your pet spends outdoors, especially in areas known for high flea and tick populations.
Avoid Wild/Stray Animals Prevent your dog from interacting with wild and stray animals, which often carry fleas and ticks.
