Quick Answer
Both are monthly flea and tick preventives, but they work very differently. NexGard is an oral chew (afoxolaner) that works from inside the bloodstream — fast-acting (kills fleas in 4–8 hours), unaffected by bathing or swimming, and the stronger choice for Flea Allergy Dermatitis and heavier infestations. Frontline Plus is a topical spot-on (fipronil + S-methoprene) — more affordable, a good option for dogs that can’t take oral products, and it comes in a cat-specific version. For most Bangalore dogs, NexGard is the more reliable all-rounder; Frontline Plus is the budget-friendly, topical alternative when used consistently and correctly.
If you’re choosing between an older, familiar spot-on and a newer chewable tablet, this is the comparison you need. Both NexGard and Frontline Plus are given monthly and both target fleas and ticks — but the way they deliver the drug changes how they perform in Bangalore’s year-round parasite pressure.
NexGard vs Frontline Plus — At a Glance

| Dosing interval | Monthly | Monthly |
| Flea kill speed | 4–8 hours | 24–48 hours |
| Spectrum | Fleas, ticks (+ Demodex) | Fleas (all life stages), ticks, lice |
| Affected by bathing/swimming | No (oral) | Avoid bathing 48h after applying; waterproof thereafter |
| Kills flea eggs/larvae | Breaks cycle by killing adults fast | Yes — S-methoprene targets eggs & larvae |
| Cat version available | No (not for cats) | Yes (cat-specific formulation) |
| Approx. cost | ₹550–900 / month | ₹350–550 / month |
| Available at HempyTails | Yes | Yes |
What They Have in Common
- Both are given monthly and cover both fleas and ticks.
- Both are well-established, widely used products with long safety records.
- Both are dosed by your dog’s weight band — weigh your dog before every purchase.
The Differences That Matter
1. Oral vs topical — and Bangalore humidity
NexGard is swallowed and works from the bloodstream, so bathing, swimming and humidity have no effect on it. Frontline Plus sits in the skin’s oil layer; it’s waterproof once settled, but you must avoid bathing for 48 hours after applying, and very frequent bathing can reduce its longevity. For dogs bathed or swum often — common in Bangalore’s climate — the oral route is more foolproof.
2. Speed of kill
NexGard kills fleas within 4–8 hours; Frontline Plus within 24–48 hours. For a dog with Flea Allergy Dermatitis, where every bite counts, NexGard’s faster kill is a real clinical advantage.
3. Infestation control
Frontline Plus has one thing NexGard doesn’t advertise: S-methoprene, an insect growth regulator that stops flea eggs and larvae developing — useful for tackling the 95% of the flea population living in your home. However, modern oral isoxazolines like NexGard control established infestations very effectively by killing adults before they lay, and in heavy infestations they tend to outperform topicals. There have also been reports of some flea resistance to fipronil over the years.
4. Cost and cats
Frontline Plus is cheaper per dose, which makes it a sensible budget choice for consistent, correct use. It also comes in a cat-specific formulation — important, because NexGard is not for cats, and dog flea products must never be used on cats.
Which Should You Choose?
- Most Bangalore dogs, maximum reliability: NexGard — fast, systemic, bath-proof.
- Dogs with Flea Allergy Dermatitis: NexGard, for the faster kill.
- Budget-conscious, consistent application: Frontline Plus.
- Dogs who can’t or won’t take a tablet: Frontline Plus (topical).
- Cats: a cat-specific product such as Frontline Plus for cats — never NexGard.
- High tick-exposure dogs: pair either with a Seresto collar for added repellent protection against tick fever.

Safety Notes
Both products have strong safety records used at the correct weight-band dose. With Frontline Plus, apply to the skin (not the coat) at the base of the neck where the dog can’t lick it, and let it dry. Isoxazolines like NexGard can rarely be associated with neurological signs in susceptible dogs, so mention any seizure history to your vet. When in doubt, dose under veterinary guidance.
Frequently Asked Questions
Is NexGard better than Frontline Plus?
For most dogs, NexGard is the more reliable all-rounder — it acts faster, works from inside so bathing doesn’t affect it, and controls heavy infestations well. Frontline Plus remains a solid, more affordable topical option, particularly for dogs that can’t take oral products and for households that also need a cat formulation. Neither is “bad”; they suit different needs.
Can I use Frontline Plus and NexGard together?
Combining them is generally unnecessary — either alone provides full monthly flea and tick cover, and doubling up offers no proven benefit for routine use. For extra tick protection in high-risk settings, a Seresto collar is usually added instead. Always check with your vet before combining products.
Does Frontline Plus still work if my dog gets wet?
Once it has settled (allow about 48 hours after application with no bathing), Frontline Plus is water-resistant. But very frequent bathing or swimming can shorten its effect. If your dog is in water often, an oral product like NexGard avoids the issue entirely.
Which is safer for my dog?
Both have long, strong safety records at the correct dose. The right choice depends more on your dog’s needs and lifestyle than on a safety gap. Discuss any seizure history (relevant to oral isoxazolines) or skin sensitivity (relevant to topicals) with your vet.
