Understanding NexGard’s Active Ingredient

To understand how NexGard works against fleas and ticks in dogs, you need to know about its active ingredient. Afoxolaner is the key component in NexGard, a powerful insecticide that disrupts the nervous system of fleas and ticks.

Once your dog ingests NexGard, afoxolaner gets to work quickly. It’s absorbed into your dog’s bloodstream and spreads throughout the body. When fleas or ticks bite your dog, they’re exposed to afoxolaner, which causes hyperexcitation and eventual death in these parasites.

This means that NexGard not only kills existing fleas and ticks on your dog but also prevents new infestations from establishing. The effectiveness of NexGard in eliminating fleas and ticks is directly linked to the potency of afoxolaner.

This active ingredient ensures that your furry friend remains protected from these pesky parasites, allowing them to enjoy a happy and itch-free life.

Mode of Action Against Fleas

Once ingested by your dog, afoxolaner in NexGard swiftly targets and disrupts the nervous systems of fleas, leading to their hyperexcitation and eventual demise. Afoxolaner works by blocking specific receptors in the fleas’ nervous system, called GABA receptors, which are essential for normal nerve functioning. By interfering with these receptors, afoxolaner causes uncontrolled activity in the fleas’ nervous system, resulting in paralysis and death of the fleas.

Unlike some traditional flea treatments that require fleas to bite your dog to be effective, NexGard works systemically. This means that NexGard starts to kill fleas before they even have the chance to bite your dog. Once the fleas come into contact with afoxolaner in your dog’s bloodstream, the process of disrupting their nervous systems begins, swiftly leading to their elimination.

Effectiveness on Ticks

NexGard effectively targets and eliminates ticks by disrupting their nervous systems, ultimately leading to their demise. Once your dog ingests NexGard, the active ingredient Afoxolaner gets to work quickly, entering the tick’s bloodstream when it bites.

Afoxolaner interferes with the ticks’ nerve receptors, causing hyperexcitation, leading to paralysis and death. This rapid action helps prevent ticks from transmitting harmful diseases to your furry friend.

It’s crucial to note that NexGard doesn’t just kill ticks present on your dog; it also disrupts the life cycle of ticks in the environment, reducing the risk of reinfestation.

Duration of Protection

When considering the duration of protection against ticks provided by NexGard, it’s important to understand how long this shield lasts to ensure continuous safeguarding of your dog.

NexGard is designed to offer a month-long defense against ticks. After administering the chewable tablet to your furry friend, the active ingredient, afoxolaner, swiftly starts working. It gets absorbed into your dog’s bloodstream, and when ticks feed on your pet, they ingest afoxolaner, which disrupts their nervous system, ultimately leading to their demise.

Safety Considerations and Side Effects

To ensure the well-being of your canine companion, it’s important to be aware of the safety considerations and potential side effects associated with using NexGard for flea and tick protection. NexGard is generally considered safe for most dogs, but like any medication, there are some factors to keep in mind. Some dogs may experience mild side effects such as vomiting, diarrhea, lethargy, or lack of appetite. These side effects are usually temporary and subside on their own as your dog’s body adjusts to the medication. If these symptoms persist or worsen, it’s advisable to consult your veterinarian.

While NexGard is safe for the majority of dogs, there have been rare reports of more serious side effects such as neurologic signs including tremors, seizures, or ataxia. If you notice any unusual behavior after administering NexGard to your dog, it’s crucial to seek veterinary advice promptly. Additionally, NexGard should be used with caution in dogs with a history of seizures.
