## Description

From the manufacturer 4fleas Spot-on for Medium Dogs (10kg up to 25kg) How it Works Johnson’s 4Fleas Spot-On for Dogs (10kg up to 25kg) uses imidacloprid , a fast-acting topical treatment, to eliminate fleas quickly and effectively. It kills fleas on contact , so they don’t have to bite your dog to die. Within 3–5 minutes of application, fleas stop biting, providing almost instant relief to your pet. The treatment kills 98–100% of fleas within 12 hours , and also kills flea larvae in your dog’s immediate surroundings, helping to break the flea life cycle in your home. Each application protects your dog for up to 4 weeks , preventing new flea infestations from taking hold. In addition to fleas, this spot-on is effective against biting lice on dogs. How to Use To apply one pipette (1.34 ml), first hold the pipette upright and snap off the tip. With your dog standing, part the fur between the shoulder blades (at the base of the neck, in front of the shoulder line). Ensure the skin is visible, and squeeze out the entire contents directly onto that one spot. Do not bathe your dog for 2 days; avoid application to broken or damaged skin. Key Features Fast Relief: Stops fleas from biting within minutes Kills on Contact: 98–100% of fleas killed within 12 hours Breaks the Cycle: Kills flea larvae in the dog’s environment Long-Lasting: Each dose prevents re-infestation for up to 4 weeks Easy Application: Simple spot-on pipette. No pills, no mess Vet-Strength Formula: Contains imidacloprid, a trusted veterinary ingredient Johnson’s 4Fleas Spot-On for Dogs (10kg - 25kg) is a topical flea treatment designed to quickly relieve and protect your dog from fleas. Upon application, this treatment’s active ingredient – imidacloprid – disperses through your dog’s skin oils, destroying fleas on contact before they can bite . This means your dog gets fast relief from itching and irritation; in fact, fleas begin to die and stop biting within just 3–5 minutes of application . Within 12 hours, virtually all fleas on your pet will be eliminated, making 4Fleas one of the fastest-acting treatments available for dogs. The benefits of Johnson’s 4Fleas Spot-On don’t stop at your pet – it also works in the environment. As treated dogs move around, tiny amounts of the active ingredient shed into areas like pet bedding and carpets. This de-activates flea larvae in the immediate surroundings of your dog , effectively breaking the flea life cycle and preventing future generations of fleas from emerging. Each pipette provides up to 4 weeks of continuous protection , ensuring that any new fleas hopping onto your dog are quickly treated before they can start an infestation. Using 4Fleas Spot-On is easy and stress-free for both dog and owner. The small, pre-measured pipette allows for quick application at the base of the dog’s neck, between the shoulder blades. The formula is non-greasy and fragrance-free , so once applied, your dog likely won’t even notice it. It’s a gentle but effective treatment that is safe for dogs between 10kg and 25kg. Regular use of a monthly preventative like Johnson’s 4Fleas Spot-On is essential to keep your dog healthy and comfortable year-round. For best results, use this spot-on treatment as part of a comprehensive flea control program. Treat all pets in the household and consider addressing the home environment with a household flea spray or fogger (such as Johnson’s 4Fleas Household Spray or Twin Fogger) to destroy any remaining eggs or larvae. By attacking fleas on multiple fronts, you can ensure a flea-free home and pet , even during peak flea season. Johnson’s 4Fleas Spot-On for Dogs (10kg - 25kg) offers pet owners a clinically proven, vet-strength solution to protect their canine friends from fleas – providing fast-acting relief and long-lasting peace of mind.

### ⭐⭐⭐⭐⭐ Amazing!
*by A***S on 14 December 2024*

I don't usually leave reviews but I feel like I should for this. My dog was suffering really bad with fleas where nothing we tried worked. This included numerous sprays and cream to repell fleas even garlic tablets but they just wouldn't budge. I came across this on Amazon and read reviews from other people and majority said it worked well so I went for it. No word of a lie within a day the fleas disappeared and going on 10 days now still not a flea in sight which is a relief for me and my dog. No more bites on my legs and my dog is no longer scratching and red raw. Would definitely recommend this product absolute life saver
