Key Health Benefits & Dual Action Profile

Flea bites can cause severe discomfort and trigger Flea Allergic Dermatitis (FAD). 4Fleas Dual Action is ideal for sensitive dogs because the active ingredient causes fleas to stop biting within just a couple of minutes of application, and kills them completely within one day. Furthermore, within 20 minutes of treatment, flea larvae in your pet's immediate environment (such as their bedding) will also be killed. Note: Fleas are a common carrier of Tapeworm eggs. If your pet has a flea infestation, it is highly recommended to follow up with a reliable wormer, such as Beaphar WormClear, to target intestinal worms.

Why Shop With Us? — Shipping & Customs Information

We provide transparent, seamless logistics to ensure your order arrives quickly and without administrative hassle.

• Fast Regional Dispatch: Daily dispatches across Ireland & UK with fully trackable premium courier services.
• Zero Tariffs or Duties: Because Northern Ireland continues to be treated as being within the EU single market for goods, all orders dispatched from our warehouse to customers in the UK or the EU are completely free from hidden tariffs, customs duties, or clearance fees.
• Exemption from EU Small-Parcel Charges: Under the EU customs rules targeting low-value imports under €150, standard non-EU parcels face a fixed €3 customs duty stacked on every single distinct item type within a parcel. Northern Ireland is entirely exempt from this regulation. When buying from us, EU customers will never face these multi-item stacked border fees or unexpected delivery charges.

Safe Usage Guidelines & Application

• Application Method: Hold the pipette upright and tap the neck so the contents fall into the main body. Twist the cap to remove it. Gently part the fur between your dog's shoulder blades until the skin is visible, and squeeze the pipette firmly to empty the contents directly onto the skin.
• Age & Status Restrictions: This product must not be used on puppies younger than 8 weeks of age. It is exclusively for use on dogs. Do not use on pregnant or lactating animals.
• Environmental Advice: If your pet currently has fleas, you must treat their environment (carpets, soft furnishings) with a household spray to prevent reinfestation. Do not put an indoor infested pet outside, as the fleas will simply stay indoors and begin biting humans.

Frequently Asked Questions

What does "Dual Action" mean?

Dual Action refers to the treatment's ability to kill parasites in two locations: it kills adult fleas and biting lice directly on your dog's coat, while simultaneously killing flea larvae in your pet's immediate environment (like their bed or favourite rug) within 20 minutes of application.

How fast does it work?

The active ingredient, Imidacloprid, is incredibly fast-acting. Fleas typically stop biting your dog within a couple of minutes of coming into contact with the treatment, and are completely killed within one day.

How long does one pack last?

Each pack contains 2 pipettes. One pipette provides up to 4 weeks of protection against fleas and biting lice. Therefore, a single pack will protect your dog for a total of 8 weeks.

Can I use this on a pregnant dog?

No. Johnson's 4Fleas Dual Action Spot On is not suitable for use on pregnant or lactating female dogs. Always consult your vet for safe alternatives during pregnancy.
