2l6 THE MANAGEMENT AND DISEASES OF THE DOG. 



A great variety of anthelmintics have been recommended ; 

 but for this particular worm there is probably nothing better 

 than castor-oil and santonine. As with the lumbricoids of 

 man, so with those of the cat and dog ; in either case they 

 seem powerless to resist the action of this remedy. In the 

 human subject I have known a grain of santonine sufficient 

 to expel a lumbricoid as large as a lob-worm ; and in the dog 

 or cat similar experiences have followed the employment of 

 from three to five grain doses. Several of my pupils have 

 adopted this mode of treatment with success. 



The employment of more powerful vermifuges is rarely 

 necessary ; and even the areca-nut powder should generally 

 be reserved for tapeworm. Areca-nut jDowder is unquestion- 

 ably a good vermifuge, as I can testify from personal experi- 

 ence ; and I observe that it is strongly recommended by 

 " Stonehenge," in his admirable memoir, " On the Manage- 

 ment of Dogs." It is, however, rather as a taeniafuge than as 

 a lumbricifuge that the merits of areca-nut powder stand out 

 most conspicuously. The powder may be given in half 

 drachm or one-drachm doses, followed by castor-oil and re- 

 peated twice or thrice in the day. In bad cases turpentine 

 may be cautiously resorted to, and, when given, should be 

 combined with twice as much either of castor or linseed oil. 

 The dose of turpentine should be rarely more than one drachm, 

 and in no case should it exceed two drachms in the very 

 largest dog. Three drachms of turpentine have been known 

 to occasion violent convulsions in the full-grown dog ■, and in 

 the case of young puppies such a dose would probably prove 

 fatal. Calomel, in one to three grain doses, is a favorite 

 remedy with some ; but, considering its varied action, it 

 should only be restored to when other remedies have failed. 

 The mechanical irritants, such as powdered tin and glass, or 

 even cowhage, should in all cases be~ eschewed, because they 

 are liable to cause much suffering without entailing any ade- 

 quate result. 



It is also worthy to remark that, after the expulsions of
