Johnson’s 4Fleas Spot-On for Dogs 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. 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.
