Bravecto vs NexGard vs Frontline: Which Tick and Flea Protection Fits Your Dog

Bravecto (fluralaner) is a chewable tablet given once every 12 weeks, NexGard (afoxolaner) is a chewable tablet given monthly, and Frontline Plus (fipronil plus S-methoprene) is a monthly topical spot-on rather than an oral tablet. All three protect against ticks, the vector for tick fever (ehrlichiosis and babesiosis), a genuinely serious disease in Indian dogs. The right choice depends on your dog's tolerance for oral medication, bathing frequency, and budget, and the specific product and dosing must come from your vet based on your dog's weight and health history.

Why this matters in India

Tick fever is one of the most common serious infectious diseases Indian vets treat, particularly in dogs who spend time outdoors, live in bungalow or ground-floor settings with access to gardens, or visit parks and grooming salons where tick exposure from other dogs is possible. Unlike in many Western markets where flea prevention is the primary driver of product choice, in India tick prevention is often the more clinically urgent consideration, since fleas, while a nuisance, do not carry a disease burden in Indian dogs comparable to tick-borne ehrlichiosis and babesiosis. This changes which product attributes actually matter here: consistency of tick coverage across the full dosing interval, and whether a product's efficacy is affected by monsoon-season bathing (a genuinely common practice for Indian dogs during and after the rains), are more practically relevant questions for Indian pet parents than they are in drier Western climates.

How each product actually works

Bravecto (active molecule fluralaner) belongs to the isoxazoline drug class. Once absorbed after oral administration, fluralaner circulates in the bloodstream and, when a tick or flea bites the dog and ingests blood, the drug binds to and overactivates specific chloride channels in the parasite's nervous system, causing uncontrolled nerve signalling and rapid death of the parasite. Because the drug remains at effective blood concentrations for an extended period, a single dose provides continuous protection for approximately 12 weeks, meaning four doses a year covers a full annual protection cycle.

NexGard (active molecule afoxolaner) is also an isoxazoline, working through the same general chloride-channel mechanism as Bravecto, but formulated for monthly dosing rather than a 12-week interval. It is given as a flavoured chewable tablet.

Frontline Plus (active molecules fipronil and S-methoprene) works differently: fipronil is applied topically and distributes through the skin's oil glands, killing adult fleas and ticks on contact by disrupting their nervous system through a different mechanism (GABA-gated chloride channel blockade) than the isoxazolines. S-methoprene is an insect growth regulator that prevents flea eggs and larvae from developing into biting adults, addressing the environmental flea life cycle rather than just adult parasites on the dog. Frontline Plus is applied monthly as a spot-on between the shoulder blades.

Bathing, swimming and monsoon considerations

This is a genuinely practical Indian-specific consideration. Because Frontline Plus is a topical product that relies on distribution through the skin's natural oils, frequent bathing, particularly with medicated or degreasing shampoos, can reduce its effective duration between applications, a real issue during Indian monsoon months when dogs often get muddy and are bathed more frequently. Bravecto and NexGard, being orally administered and working through the bloodstream rather than the skin surface, are not affected by bathing or swimming in the same way, which is one practical reason many Indian vets lean toward an oral option for dogs who are bathed frequently or enjoy water play.

What it costs in India (2026)

Prices vary meaningfully by your dog's weight tier (smaller dogs use smaller, cheaper doses of all three products) and by retailer; these figures are illustrative ranges from Indian online pet pharmacy listings at the time of writing, not a fixed national price, so confirm current pricing with your vet or pharmacy before purchase. Buying through your regular vet clinic rather than an unfamiliar online seller also gives you a reliable point of contact if you have questions about a dose or notice anything unusual after administration, which is worth the sometimes-slightly-higher price for many first-time users of these medications.

Which vets tend to prefer, and when

There is no single universally "best" product; mainstream veterinary guidance treats all three as legitimate options when used correctly, and the right choice depends on individual factors. A dog who is difficult to medicate orally, or who has a sensitive stomach, may do better on a topical option despite the bathing caveat. A dog who is bathed frequently, swims often, or whose owner finds monthly topical application messy or difficult (some dogs resent the wet application feeling on their skin) is often better served by an oral option. Owners who struggle to remember monthly dosing may prefer Bravecto's 12-week interval simply because it requires four decisions a year instead of twelve. Dogs with a history of neurological conditions such as seizures are a specific consideration your vet needs to know about before prescribing any isoxazoline-class product (which includes both Bravecto and NexGard), since this drug class has been associated with rare neurological side effects in susceptible individual dogs, though this remains uncommon overall.

A simple way to decide between them

If you want the fewest number of dosing decisions per year and your dog tolerates oral chewables well, Bravecto's 12-week interval is worth discussing with your vet. If your dog refuses chewable tablets or you prefer a monthly rhythm you can pair with other monthly reminders (like a monthly grooming or vet check-in), NexGard's monthly oral format may suit better. If your dog cannot tolerate oral isoxazoline-class medication for a specific medical reason your vet has flagged, or you prefer an established, off-patent option and are prepared to manage the bathing caveat, Frontline Plus remains a reasonable choice. None of these are a wrong choice in isolation; the wrong choice is picking one without discussing your specific dog's health history, bathing habits, and temperament with a vet first, since the products differ enough in mechanism and format that a generic "best one" answer does a disservice to individual dogs with individual needs.

When to see a vet

• Book a consult before starting any of these products: to get correct weight-based dosing and to disclose any history of seizures, neurological conditions, or known sensitivities, all of which affect which product class is appropriate for your specific dog.
• Go now: unusual tremors, wobbliness, or neurological signs appearing after a dose of any isoxazoline-class product; while uncommon, these should be evaluated promptly rather than waited out.
• Book within a week: if you find a tick attached to your dog despite being on a preventive, since no product offers absolute 100% prevention and your vet may want to check for early tick-borne disease signs.
• Routine: if your dog develops mild, transient loose stool or reduced appetite for a day after a dose, mention it at the next visit but this does not typically require an emergency visit on its own.

Frequently asked questions

Kaunsa tick tablet sabse accha hai mere kutte ke liye?

Koi ek product sabse accha nahi hai sabke liye, yeh depend karta hai aapke kutte ke weight, health history, aur kitni baar nahalate hain us par. Apne vet se discuss karke sahi product aur dose choose karein.

Can I switch between Bravecto, NexGard and Frontline?

Discuss timing with your vet before switching, since you want to avoid a gap in protection or accidentally overlapping doses of the same active drug class. Your vet can advise on when the current product's protection window ends and when to safely start the new one.

Do these products protect against tick fever directly, or just kill ticks?

They work by killing the tick before or shortly after it bites, which reduces (but does not with absolute certainty eliminate) the opportunity for tick fever pathogens to be transmitted, since transmission can occur even during a brief attachment in some cases. They are a prevention tool, not a treatment for existing tick fever.

Are these products safe for puppies?

Each product has a minimum age and weight for use, which varies by product and is stated on the packaging and by your vet; do not use any of these in a puppy below the manufacturer's stated minimum age or weight without your vet's specific guidance.

Why is Frontline sometimes cheaper than Bravecto or NexGard?

Frontline Plus uses an older, off-patent drug class (fipronil), which is generally less expensive to manufacture than the newer isoxazoline class used in Bravecto and NexGard, which typically command a price premium as more recently developed drug technology.

Is a combined flea, tick and heartworm product available in India?

Some combination parasiticide products covering multiple parasite types are available in India, though availability varies by brand and region. Ask your vet which combination products they stock or recommend, since consolidating protections into fewer doses can be more convenient for some owners.
