recommendations:
One Johnson’s 4Fleas11.4mg tablet should be given to small dogs weighing 1 kg to
11.0 kg when a flea infestation is detected. The frequency of treatment depends on
the degree of infestation. In the case of a severe flea infestation, it may be necessary
to treat the animals every day or every other day, until the flea infestation is
controlled. Treatment may be resumed if fleas reappear. No more than one treatment
should be given per day.
Tablets should be given orally, with or without food. In order to improve palatability,
tablets can be disguised in a small quantity of food immediately prior to
administration.
