Johnson 4fleas Spot-On Puppies is a fast-acting, topical veterinary treatment designed to prevent and treat flea infestations on very small dogs. It belongs to the AVM-GSL legal category in the UK, meaning it is an over-the-counter medicine that does not require a prescription.
Key Specifications & Eligibility
-
- Target Weight: For puppies and miniature dogs weighing under 4 kg.
- Minimum Age: Safe for puppies over 8 weeks of age.
- Active Ingredient: Imidacloprid (40 mg per 0.4 ml pipette).
- Pack Size: Commonly sold as a 2-pack of pipettes (providing up to 2 months of protection total).
How it Works & Benefits
-
- Dual-Action Relief: It kills adult fleas on contact on your puppy’s body, meaning the fleas do not need to bite your pet to be eliminated. It also treats biting lice (Trichodectes canis).
- Fast-Acting: Fleas stop biting within 3 to 5 minutes of application, and virtually all adult fleas are killed within 12 to 24 hours.
- Environmental Control: As your puppy moves around your home, microscopic traces of the active ingredient shed onto carpets and bedding. This kills flea larvae in the home within 20 minutes of contact, breaking the flea lifecycle.
- Duration: Each individual pipette protects your puppy for up to 4 weeks.
- Water Resistant: The formula remains effective even if your puppy gets caught in the rain or goes for a swim, though frequent shampooing should be restricted.
Application Instructions
- Hold the pipette upright and twist off the cap.
- Part your puppy’s fur at the base of the neck (between the shoulder blades) until the skin is visible.
- Place the tip of the pipette directly against the skin and squeeze firmly to empty the liquid content entirely onto one spot.
- Avoid applying to long fur or directly on top of wounds, and ensure pets cannot lick the application site
