If the mixture is not retained, from an eighth[1] to half a grain of santonine, with from half[1] to two grains of jalapin, may be given, made into a pill, twice a week half an hour before food. When six weeks old, fox-terriers and other breeds of similar size and strength, and also, of course, bigger ones, may be dosed with powdered areca nut and santonine. Give one grain of the former to every pound the dog weighs, and to the dose of this medicine add from the eighth[1] to half a grain of santonine. This may be given in a cachet, and about half an hour afterwards give the puppy a drink of warm milk. Should the bowel not operate freely in the course of an hour, from half[1] to two teaspoonfuls of castor oil is recommended. Repeat the vermifuge in the course of a few days. “Ruby” is also an excellent remedy for worms in young dogs. It is a good plan to dose puppies regularly from time to time, say once a month, for worms. With regard to the treatment of tapeworms in adult dogs, there is nothing better than the old-fashioned remedy, freshly powdered areca nut. The dose is one grain to every pound the dog weighs, but more than two drachms should never be given at a time to the biggest dog. Unfortunately this medicine often induces vomiting, but if it is given in cachets it is less likely to do so. About half an hour after the medicine has been administered some warm milk or clean soup may be given the dog to drink, and a couple of hours after the dose from a dessertspoonful[1] to two tablespoonfuls of castor oil should be given. Another good remedy for tapeworm is the oil of male fern, and the doses are the same as for areca nut. This medicine may be bought in gelatine capsules, but castor oil must be given afterwards, as recommended after the previously mentioned remedy. It is advisable to dose all adult dogs for worms, whether they exhibit any symptoms of having these parasites or not, about three or four times a year. =Worm (Maw)=: _Symptoms_: A dog is said to have maw worms when pieces or segment of tapeworm are found adhering to the back parts. These are not distinct worms, but segments of tapeworm, which come away naturally when a worm is breaking up in the bowels, due to natural causes and changes. _Treatment_: The same as for tapeworms. =Wounds=:
