NexGard: What is it Used For?

Hey guys! Ever wondered what NexGard is all about and what it's actually used for? Well, you've come to the right place. Let’s dive deep into the world of NexGard, a popular medication for our furry friends. We'll explore its uses, benefits, and everything you need to know to keep your dog healthy and happy. So, let's get started!

What Exactly is NexGard?

NexGard is a chewable tablet that protects dogs from fleas and ticks. It's a brand name for afoxolaner, an insecticide and acaricide. This medication is designed to kill adult fleas and ticks and is approved for use in dogs and puppies that are at least 8 weeks old and weigh 4 pounds or more. Administered orally, NexGard offers a convenient and effective way to keep your canine companion safe from these pesky parasites.

How Does NexGard Work?

Afoxolaner, the active ingredient in NexGard, works by interfering with the nervous system of fleas and ticks. Specifically, it blocks the passage of chloride ions through GABA-gated chloride channels in the parasites’ nerve and muscle cells. This disruption leads to uncontrolled nervous system activity, resulting in paralysis and death of the fleas and ticks. Because mammals have a different nervous system structure, afoxolaner is safe for dogs when used as directed.

Key Benefits of NexGard

  • Effective Flea and Tick Control: NexGard is highly effective in killing fleas and ticks, providing fast and reliable protection.
  • Convenient Administration: Being a chewable tablet, NexGard is easy to give to your dog, unlike topical treatments.
  • Month-Long Protection: A single dose of NexGard provides protection for a full month, making it a convenient option for busy pet owners.
  • Safe for Most Dogs: NexGard is safe for most dogs and puppies over 8 weeks of age and weighing at least 4 pounds.
  • No Messy Application: Unlike topical treatments, NexGard doesn't leave any residue on your dog’s fur, so there’s no need to worry about it rubbing off on furniture or children.

Why is NexGard Prescribed?

Okay, so why do vets prescribe NexGard? The main reason is to protect dogs from the health issues associated with flea and tick infestations. Fleas and ticks aren't just annoying; they can cause a range of problems, from mild skin irritation to serious diseases. By using NexGard, you're taking a proactive step in safeguarding your dog’s health.

Preventing Flea Infestations

Fleas can cause intense itching and discomfort for dogs, leading to excessive scratching, hair loss, and skin infections. Some dogs are allergic to flea saliva, which can result in flea allergy dermatitis (FAD), a condition that causes severe skin inflammation and discomfort. NexGard effectively kills fleas, preventing infestations and alleviating these symptoms.

Preventing Tick-Borne Diseases

Ticks are carriers of various diseases, such as Lyme disease, ehrlichiosis, and anaplasmosis, which can have serious and long-lasting effects on your dog’s health. Lyme disease, for example, can cause lameness, joint pain, and kidney problems. Ehrlichiosis can lead to fever, lethargy, and bleeding disorders. By killing ticks, NexGard helps prevent the transmission of these dangerous diseases.

Controlling Flea Allergy Dermatitis (FAD)

For dogs with FAD, even a single flea bite can trigger a severe allergic reaction. Controlling flea populations is crucial for managing this condition. NexGard provides rapid relief by killing fleas quickly, reducing the risk of allergic reactions and improving the dog’s quality of life. Regular use of NexGard can significantly decrease the incidence and severity of FAD flare-ups.

Preventing Anemia

In severe flea infestations, particularly in puppies or small dogs, blood loss from flea bites can lead to anemia. Anemia can cause weakness, lethargy, and even be life-threatening if left untreated. By preventing flea infestations, NexGard helps protect dogs from developing anemia.

Common Conditions NexGard Treats and Prevents

Let's break down the specific conditions that NexGard is designed to tackle. Knowing what NexGard prevents will help you understand why it’s such a valuable tool in pet care.

Flea Infestations

NexGard is highly effective in treating and preventing flea infestations. It kills adult fleas before they can lay eggs, thus breaking the flea life cycle. This is crucial for preventing re-infestations and keeping your dog comfortable. Signs of a flea infestation include excessive scratching, biting at the skin, and visible fleas or flea dirt in the fur.

Tick Infestations

NexGard is also effective against several types of ticks, including:

  • Black-legged tick (Deer tick)
  • American dog tick
  • Lone star tick
  • Brown dog tick

By killing these ticks, NexGard helps prevent the transmission of tick-borne diseases. Regular use of NexGard is especially important for dogs that spend time outdoors in areas where ticks are prevalent. Ticks can be found in grassy, wooded, and bushy areas, so it's important to be vigilant about tick prevention.

Lyme Disease

Lyme disease is a bacterial infection transmitted by the black-legged tick (deer tick). It can cause a range of symptoms in dogs, including lameness, joint pain, fever, and lethargy. In severe cases, Lyme disease can lead to kidney damage and neurological problems. By preventing tick bites, NexGard helps reduce the risk of Lyme disease.

Ehrlichiosis

Ehrlichiosis is another tick-borne disease that can affect dogs. It is caused by bacteria transmitted by the brown dog tick, American dog tick, and lone star tick. Symptoms of ehrlichiosis include fever, lethargy, loss of appetite, and bleeding disorders. Early diagnosis and treatment are crucial to prevent chronic complications. NexGard helps protect dogs from ehrlichiosis by killing the ticks that transmit the disease.

Anaplasmosis

Anaplasmosis is a tick-borne disease caused by bacteria transmitted by the black-legged tick and the brown dog tick. Symptoms of anaplasmosis can include joint pain, fever, lethargy, and loss of appetite. In some cases, anaplasmosis can lead to more severe complications, such as kidney damage and neurological problems. By preventing tick bites, NexGard helps lower the risk of anaplasmosis.

Demodectic Mange

While not a primary treatment for demodectic mange, some studies suggest that afoxolaner, the active ingredient in NexGard, may be effective in treating this skin condition caused by Demodex mites. Demodectic mange can cause hair loss, skin lesions, and inflammation. If your dog has demodectic mange, consult with your veterinarian to determine the best course of treatment.

How to Administer NexGard

Giving NexGard to your dog is super easy! Because it’s a chewable tablet, most dogs take it without any fuss. Here’s a quick guide:

  1. Check the Dosage: Make sure you have the correct dosage for your dog’s weight. NexGard comes in different strengths, so it’s important to use the right one.
  2. Offer the Tablet: Simply offer the chewable tablet to your dog. Most dogs will eat it like a treat. If your dog is hesitant, you can try wrapping it in a small piece of cheese or peanut butter.
  3. Administer with Food: If your dog is still reluctant to take the tablet, you can give it with a meal. This can help mask the taste and make it more appealing.
  4. Ensure It’s Swallowed: Watch your dog to make sure they swallow the entire tablet. If they spit it out, try again.
  5. Wash Your Hands: After administering the tablet, wash your hands thoroughly.

Potential Side Effects

Like all medications, NexGard can have potential side effects. While most dogs tolerate NexGard well, it’s important to be aware of possible reactions. Common side effects may include:

  • Vomiting
  • Diarrhea
  • Lethargy
  • Loss of appetite
  • Skin irritation

In rare cases, some dogs may experience more serious side effects, such as seizures. If you notice any unusual symptoms after giving your dog NexGard, contact your veterinarian immediately.

Precautions

Before starting your dog on NexGard, it’s important to consider a few precautions:

  • Consult Your Vet: Always talk to your veterinarian before starting any new medication for your dog. They can help determine if NexGard is the right choice for your pet and advise you on the correct dosage.
  • Age and Weight: NexGard is approved for use in dogs and puppies that are at least 8 weeks old and weigh 4 pounds or more. Do not give NexGard to puppies younger than 8 weeks or dogs weighing less than 4 pounds.
  • Medical History: Inform your veterinarian about any existing medical conditions your dog has, as well as any other medications they are taking. This can help prevent potential drug interactions.
  • Seizure History: Use with caution in dogs with a history of seizures. If your dog has a seizure disorder, discuss the risks and benefits of NexGard with your veterinarian.

Conclusion

So, to wrap it up, NexGard is a fantastic option for keeping your dog safe from fleas and ticks. It’s easy to administer, provides month-long protection, and helps prevent a range of nasty diseases. Always chat with your vet before starting any new treatment, but NexGard is definitely a strong contender for keeping your furry pal happy and healthy!
