Advantage 100 Flea Treatment for Dogs weighing 4-10kg


Advantage 100 is designed for the prevention and treatment of flea infestations on dogs weighing between 4 and 10 kilograms. It is also effective for treating biting lice on dogs.

How Advantage Works

Advantage is a reliable flea treatment that prevents and treats flea infestations. It also has an environmental larvicidal effect, controlling the flea lifecycle in the pet's surroundings.


- Fleas are eliminated within one day following treatment. - A single treatment prevents further flea infestation on dogs for up to four weeks. - Suitable for the treatment of flea allergy dermatitis (FAD) in dogs, if diagnosed by a veterinary surgeon.

Usage Instructions

- Repeat treatment after four weeks. - Do not treat more frequently than once weekly, even if re-treatment is necessary.

Re-infestation and Environmental Considerations

- Re-infestation from new fleas in the environment may continue to occur for six weeks or longer after treatment is initiated. - Depending on the level of fleas in the environment, more than one treatment may be required. - For enhanced environmental control, consider using an appropriate environmental treatment against adult fleas and developing stages. - To further reduce the environmental challenge, it is recommended to treat all cats, dogs, and rabbits in the household.

Effectiveness in Wet Conditions

The product remains effective even if the animal becomes wet, such as after exposure to heavy rain or swimming (for dogs). However, re-treatment may be necessary based on the presence of fleas in the environment. In such cases, do not treat more frequently than once weekly.

Special Considerations

- Treating a nursing bitch with Advantage provides protection against fleas for the entire litter. - Advantage can be used on puppies from 8 weeks of age.
