Considering the accurate bodyweight of the animals is important before administering the medicine. The usual prescribed dosage for the treatment of adult dogs and cats is 100mg/2.2lbs. For puppies and kittens that are less than six months of age, administer 50mg/2.2lbs for 3 days continuously. The medication is safe to be used in pregnant animals too; provide 25mg/lbs from 40 days of pregnancy. The medication should be mixed with food.
