Nexgard for Medium Dogs 10.1-24 lbs (Blue) 28mg

It comes as a soft, tasty beef-flavored chewable that is accepted by most dogs, meaning no residue, greasing or staining on the dog’s coat. NexGard monthly chews kill fleas before they can lay eggs, ensuring your dog stays protected from the subsequent infestations too.

It begins killing fleas within four hours after administration and kills the majority of them at eight hours, as indicated by a lab study referenced on the label. Additionally, Nexgard tick treatment is indicated to prevent infections (Borrelia burgdorferi) that cause Lyme disease as a direct result of killing black-legged vector ticks.

Nexgard FAQ

How early can I start treating my dog with NexGard chews?

NexGard Chewables is indicated for use in puppies and dogs from 8 weeks of age that weigh at least 4 lbs.

How does NexGard Chewable work?

NexGard Chewable contains the active ingredient, afoxolaner. After ingestion, the chew is absorbed into the dog's bloodstream. As soon as fleas and ticks take a bloodmeal from the treated dog, they ingest afoxolaner. It overstimulates the nervous system of these parasites, causing hyperexcitation in them. This results in paralysis and death of fleas and ticks.

How effective is NexGard Chewables?

According to a laboratory study cited in the label, NexGard Chews start killing fleas four hours after ingestion and demonstrate nearly complete efficacy at eight hours. This flea & tick treatment provided more than 90% effectiveness against various tick species at 72 hours after tick infestations, as per another lab study referenced in the label.

What does NexGard Chews protect my dog against?

NexGard chews protect dogs against fleas and ticks for one month. It kills adult fleas and treats and controls American Dog tick, black-legged tick, lone Star tick, brown dog tick and longhorned tick infestations. It is also indicated to prevent Lyme disease due to the direct result of killing black-legged vector ticks.

How often should I give NexGard to my dog?

NexGard is a monthly flea and tick treatment for dogs. You should administer one chew every month throughout the year for your dog's uninterrupted protection.

How soon does NexGard begin killing parasites?

According to a laboratory study cited in the label, NexGard Chews started killing fleas four hours after initial administration.

Why do I still see fleas on my dog after treating with NexGard?

Adult fleas you see on your pet only comprise up 5% of the total flea population. The remaining 95% include the immature life stages, including flea eggs, larvae, and pupae, which you may see anywhere in the house where the infested dog spends time. As your dog moves through these areas, newly emerged fleas jump on the pet. NexGard chew should be able to kill these fleas before they can reproduce. To keep your pet from re-infesting fleas, you should continue using NexGard throughout the year.

My dog doesn't go outside. Do I still need to give NexGard to this dog?

Your pet is always at risk of flea and tick infestations. They can get infected when they go out for their business. Fleas can get inside your home by hitchhiking on your shoes or clothes and infect your dog. Therefore, it is necessary to treat all your dogs with NexGard even if they don't go out.

How long before I can bathe my dog after giving NexGard?

Since NexGard is an oral treatment, bathing or shampooing your dog after treatment shall not impact its efficacy.

My dog vomited after giving NexGard; what should I do?

If your dog vomits within two hours of administering NexGard, give another full dose. If the dog vomits after two or more hours, consult a vet before redosing.

Can I combine NexGard Chews and Frontline Plus?

Both NexGard and Frontline Plus are safe for dogs when used individually. However, you should consult a veterinarian before combining these treatments.
