How to Apply FRONTLINE Spot On

1. Hold the pipette upright and tap the neck so the liquid settles in the main body, then snap off the top along the scored line.
2. Part your dog's coat between the shoulder blades until you can see the skin.
3. Place the pipette tip against the skin and squeeze gently to empty the full contents directly onto the skin — not onto the fur.

Tip: apply in the evening, keep the area dry, and avoid bathing your dog or letting them swim for 48 hours after treatment.

Frequently Asked Questions

How often should I use FRONTLINE Spot On on my dog?

Apply one pipette every 4 weeks for optimal, continuous protection. Protection against fleas lasts up to 2 months and against ticks up to 1 month per application.

Is this the right size for my dog?

This pack is for medium dogs weighing over 10kg and up to 20kg. Weigh your dog before purchase — if your dog is under 10kg or over 20kg, choose the small or large dog pack instead.

What is the active ingredient in FRONTLINE Spot On?

FRONTLINE Spot On contains fipronil, a proven insecticide that kills adult fleas, ticks and biting lice on contact through your dog's coat.

Can I bathe my dog after applying it?

Wait at least 48 hours after application before bathing or swimming. FRONTLINE remains effective with normal bathing afterwards (no more than once a week is recommended).

My dog still has fleas after treatment — is that normal?

Yes, temporarily. New fleas from the environment can jump onto your dog for weeks after treatment — FRONTLINE kills them within 24 hours of contact. For a home infestation, also treat carpets and bedding with a household flea spray and vacuum regularly, and make sure every cat and dog in the house is treated.

Is FRONTLINE Spot On the same as FRONTLINE Plus?

No. Spot On is the original fipronil-only formula that kills adult fleas, ticks and lice. FRONTLINE Plus adds (S)-methoprene, which also stops flea eggs and larvae developing. Spot On remains a highly effective, more affordable choice for routine protection.

Safety: For animal treatment only. Read the enclosed leaflet fully before use. Wash hands after applying and keep out of reach of children. Do not allow your dog to swim in ponds or waterways for 2 days after treatment, as fipronil can harm aquatic life. Consult your vet if irritation persists.
