Fleas and ticks turn your lively, tail-wagging dog into a scratching, miserable mess. That's exactly where NexGard for dogs steps in. A lot of dog owners have come to rely on it and for good reason. It's a soft, chewable tablet your dog takes once a month, and it handles both fleas and ticks without the fuss of sprays or spot-on treatments. In this guide, we'll walk you through the full picture: how NexGard actually works inside your dog's body, how to get the dose right, what side effects to watch for, and what makes it the go-to choice for so many households with dogs.
What Is NexGard for Dogs?
NexGard is a monthly, beef-flavoured chewable tablet designed to protect dogs from fleas and ticks. Made by Boehringer Ingelheim, one of the world's leading animal health companies, it's one of the most vet-recommended parasite treatments available today.
The active ingredient in NexGard for dogs is afoxolaner, a powerful insecticide and acaricide that targets the nervous system of parasites. Because it's delivered in a tasty chew rather than a spot-on or collar, most dogs take it like a treat. No mess, no fuss, no chasing your dog around the garden.
NexGard vs. NexGard PLUS: What's the Difference?
You'll often see both names on shelves and it's worth knowing the distinction before you buy.
- NexGard: Targets fleas and ticks. Afoxolaner only. Great for flea and tick-focused protection. Ideal for most everyday dog owners.
- NexGard PLUS®: Fleas, ticks and heartworm. Adds milbemycin oxime. Also covers hookworms and roundworms. One-and-done broad-spectrum coverage.
For most dog owners, standard NexGard for dogs is exactly what they need. If your vet recommends broader internal parasite coverage, NexGard PLUS steps that up significantly. When in doubt, ask your vet, they'll know your dog's specific risk profile.
How Does NexGard Work?
NexGard does its job quietly, working from within. Once your dog chews and swallows the tablet, the active ingredient enters the bloodstream and essentially turns your dog into a no-go zone for parasites.
Any flea or tick that bites and feeds ends up ingesting nexgard afoxolaner for dogs and that's where things go wrong for them. Their nervous system gets hit hard, ending in paralysis and, ultimately, death.
One thing dog owners genuinely appreciate? The NexGard for dogs formula doesn't budge. Bath time, a swim at the lake, a downpour, none of it affects how well it works. That makes it a solid pick for dogs who don't exactly stay clean. Month after month, it keeps doing its job — so your dog stays comfortable, itch-free, and parasite-free.

How Afoxolaner Targets Fleas and Ticks
Afoxolaner belongs to a class of compounds called isoxazolines. Once your dog swallows the chew, it absorbs into the bloodstream. When a flea or tick bites your dog and ingests that blood, the afoxolaner interferes with their nervous system — specifically blocking chloride ion channels causing uncontrolled neural activity and, ultimately, death of the parasite.
The critical thing here is that the drug works systemically, meaning it doesn't need to sit on the skin surface. The parasite has to bite to be affected, which is why it's classified as a treatment and prevention tool rather than a repellent.
How Quickly Does NexGard Start Working?
When your dog is dealing with fleas, every hour counts. Here's roughly what to expect after giving them a NexGard for dogs chew:
- Within the first 30 minutes, it starts taking down existing fleas.
- By the 8-hour mark, flea elimination hits full effectiveness.
- Push that to 12 hours, and any newly arrived adult fleas get eliminated before they even get the chance to reproduce.
- Give it 48 hours, and the majority of ticks from a fresh infestation are gone too.
How Long Does NexGard Last?
One NexGard chew keeps your dog covered for roughly four weeks. Staying on a monthly schedule means there's no window for fleas or ticks to sneak back in, something most vets strongly suggest keeping up regardless of the season, since these parasites don't necessarily die off in cooler weather. Skipping even a single dose can open the door for reinfestation.

What Does NexGard Treat and Prevent?
NexGard for dogs is specifically indicated for:
- Flea infestations: including Ctenocephalides felis and C. canis.
- Tick burdens: from brown dog ticks (Rhipicephalus sanguineus) to Haemaphysalis species and a handful of others, are brought firmly under control.
- Flea Allergy Dermatitis (FAD) gets stopped before it ever starts, since fleas are wiped out before a single bite sets off that miserable allergic chain reaction.
- Household flea contamination prevention: fleas are killed before they can lay eggs.
After treatment, most ticks will be killed within 48 hours. However, since attachment of individual ticks can't be fully excluded, transmission of some tick-borne diseases may still occur in unfavourable conditions. Always check your dog after outdoor activity.

NexGard Dosage Guide for Dogs
The recommended dose is 2.5 mg of afoxolaner per kg of body weight, administered orally once a month. Here's the weight-based dosing guide for NexGard for dogs:
For dogs over 50 kg, combine appropriate tablet sizes to reach the correct dose. NexGard is approved for use in puppies 8 weeks of age and older, and dogs weighing at least 2 kg.
How to Give NexGard to Your Dog
One of NexGard's biggest advantages is its ease of administration. Most dogs willingly eat the beef-flavored chew directly from your hand. If necessary, you can place the tablet in a small amount of food.
- Choose the right size: Weigh your dog and select the correct tablet based on the dosing chart above. Never guess, using the wrong size under-doses or wastes product.
- Offer it by hand: Most dogs take NexGard for dogs directly from your palm like a treat. If your dog is suspicious, try offering it with their regular meal or mixed into a small portion of food.
- Encourage chewing: Let your dog take their time with it, the chew only does its job if they actually bite through it instead of swallowing it in one go. Stick around for a bit to make sure they've gotten the whole thing down.
- Mark the date: Jot the date somewhere you'll actually see it, a phone reminder each month works like a charm.

NexGard Side Effects in Dogs
NexGard flea and tick treatment for dogs tends to sit well with most dogs, though every pup is built a little differently. A handful may hit a rough patch after their first dose or two:
- an upset stomach.
- loose stools.
- low energy.
- turning their nose up at dinner.
These usually sort themselves out within a day.
That said, ring your vet if symptoms persist beyond 24 hrs, muscle tremors or seizures, signs of allergic reaction, or accidental human ingestion.
How to Store NexGard
Keeping NexGard for dogs stored the right way makes a real difference in how well it works.
- Find a dry spot in your home.
- Somewhere that stays under 30°C and doesn't catch direct sunlight.
- A drawer or cabinet usually does the trick.
- Make sure kids and pets can't get into it.
- Leave the tablets sealed in their blister pack until you're actually ready to use one.
NexGard vs. Other Flea and Tick Treatments
There are many flea and tick products available, including topical treatments, collars, sprays, and oral medications.
Oral treatments like NexGard for dogs remove the mess of topicals and the safety concerns that collars can pose around children and other pets. For active dogs who swim or bathe regularly, a systemic chew is particularly practical.
