What is Nexgard?

Nexgard is a monthly chewable flea and tick preventative for dogs. It contains the ingredient afoxolaner, which kills fleas, ticks, and other parasites quickly and effectively. It not only helps protect your dog from these pests, but also contributes to their overall wellbeing by keeping them free of disease-carrying parasites.

It is easy to administer and comes in a variety of flavors that your dog will love. Nexgard is safe for dogs of all sizes and breeds, and it’s even approved by the FDA for use on puppies as young as 8 weeks old.

With its convenient dosing schedule, you can easily keep your pup protected from nasty parasites throughout the year. So, if you’re looking for a safe and effective way to protect your pup from fleas and ticks, Nexgard is an excellent choice!

How Does Nexgard Work?

Nexgard works by targeting fleas and other pests through an insecticide called afoxolaner. This insecticide is quickly absorbed into the pet’s bloodstream after ingestion, killing any adult fleas or ticks that it comes into contact with. It then continues to spread throughout the body, protecting your pet from any future infestations for an entire month. 

Additionally, Nexgard kills flea eggs and larvae before they have a chance to become full-grown adult fleas, helping to break the life cycle of these pests and preventing future infestations. 

By using this easy-to-administer oral chewable tablet your pet can be kept safe from flea and tick infestations for a full month. Nexgard also provides protection against three other dangerous pests, including American dog ticks, Lone Star ticks, and deer ticks. 

With its fast-acting formula and long-term protection, this flea and tick treatment from Nexgard is the perfect solution for keeping your pet healthy and pest free.  With Nexgard, you can rest easy knowing that your pet is safe and protected.

How is Nexgard Administered?

Nexgard is easy to administer and comes in a variety of flavors that your dog will love. It is available as a monthly chewable tablet that can be fed directly to your dog or mixed into their food.

It is important to follow the instructions on the packaging when administering NexGard, as overdosing can result in serious side effects for your pet. It is also important to note that NexGard should not be administered more than once every month, as this could result in a toxic buildup of the active ingredient afoxolaner in your pet’s body.

Always follow your veterinarian’s instructions and read the product label carefully before administering Nexgard to your pet. For best results, give the medication around the same time each month. It is important to not skip doses as this will reduce the effectiveness of Nexgard in protecting against fleas and ticks. In addition, it is advised to not give Nexgard to your pet if they are pregnant or lactating unless specifically instructed by your veterinarian. If you have any questions about administering Nexgard or about the product in general, talk to your veterinarian for more information.

This medication is available through a prescription from your veterinarian and should always be administered under their guidance and direction. If you have any concerns or questions, speak to your veterinarian before giving Nexgard to your pet.

How Much Does Nexgard Cost?

Generally, a single dose of Nexgard for dogs weighing 4 to 10 pounds costs between $25 and $35 while a single dose for dogs weighing 11 to 24 pounds costs between $35 and $60. For larger dogs over 25 pounds, the cost increases to between $60 and $100 for a single dose.

For cats, the cost of Nexgard is generally lower than dogs, with a single dose costing around $15 to $20.

It’s important to note that these costs may vary depending on where you purchase the medication from and any additional promotions or discounts available.
