Questions and answers

Is Frontline Plus worth it over cheaper flea treatments?
It combines an adulticide and an insect growth regulator, so it hits fleas at every life stage, which many budget products do not. At $40.98 for 3 doses at Amazon as of November 4, 2026, it costs about $13.66 per month of protection.
How does Frontline Plus differ from original Frontline?
Original Frontline contains only fipronil and kills adult fleas. Frontline Plus adds (S)-methoprene, which stops eggs and larvae from developing, so it does more to break the infestation cycle.
Does Frontline Plus still work after my dog swims?
Yes. The label says the waterproof formula stays active after swimming, bathing or grooming. Wait until the application site is dry before letting the dog swim.
Can I use Frontline Plus on puppies and pregnant dogs?
It is labeled for dogs 8 weeks and older and is safe for breeding, pregnant and lactating dogs. Do not use it on puppies younger than 8 weeks.
What is in the box?
The 3-dose pack contains three single-dose applicators, one per month. The 6-dose pack covers six months.
When is the best time to buy Frontline Plus?
Prices vary by store and pack size, and flea season drives demand up in spring and summer. Compare per-dose prices across the 3-pack and 6-pack, since the larger pack is often cheaper per dose.
