Pinkroot is a drug which has been much used as a vermifuge, and is reasonably safe and reliable. In very large doses it has a narcotic effect, but this is altogether obviated by combining it with cathartics. The fluid extract of pinkroot and senna is a combination which acts admirably in many cases of worms in puppies, causing little or no gastric disturbance. The dose for them when four or five weeks old is fifteen drops; for matured dogs, from one to two teaspoonsful in a little water. In all cases this remedy should be given twice a day for three or four days, after which a generous dose of castor oil should be administered.

In giving medicines for the destruction of worms, certain precautions in feeding should be observed. If but one, and a large dose of a drug is to be depended upon, food should be withheld until after the bowels have moved freely. If the drag has to be given three or four days, the diet should be simple and as limited as the condition of the animal will permit, and as long an interval as possible between the feeding and the administration of the medicine be allowed.

Other drugs, among them areca nut, are to a certain extent active in the destruction of the round-worm; they are however more deadly to the tapeworm and will be considered among the remedies advised for the removal of that pest.

Considering the great fatality among puppies caused by worms, not alone of the greatest importance is the treatment after their existence is obvious, but a means preventive is equally as urgently demanded.
