Variola : Dogpox. 361 



Symptoms. After a febrile condition of variable length, but 

 usually of a high intensity, red spots appear on the head, neck, 

 chest, belly or inside the arms and thighs, at first like flea bites, 

 but passing through the stage of papule to become vesicular on 

 the sixth day. About the ninth or tenth day they become 

 purulent, and in two or three days more a black, concave, 

 circular crust has formed which is soon detached. The eruption 

 may be local or general, discrete or confluent and the issue of the 

 case will depend much on this character. In exceptional cases 

 the eruption invades the mouth, eye, throat, stomach, or intes- 

 tines. Croker notes the accompaniment of a fatal lobular 

 catarrhal pneumonia. 



It must be carefully distinguished from urticaria, eczema, and 

 eruptions due to pustulating irritants. 



Treatment is in the main the same as for .sheep, care being 

 taken to secure prefect cleanliness, pure air, dry clean litter, 

 easily digested food, and protection from crowding, undue heat, 

 cold or wet. Buttermilk and other acidulous and diuretic drinks 

 are recommended, and careful attention to the state of the bowels 

 throughout. 



Prevention is still more important, and better than any treat- 

 ment would be the most rigorous measures for its extinction 

 along the lines laid down for sheep pox. Whether the infection 

 has been derived from man or sheep it must be looked on as 

 eminently dangerous to the class of animal from which it 

 originated, and every available means used for its extinction. 



DOG POX : VARIOLA CANINA. 



Dog pox is rare, the affection occurring especially in the 

 young. It is said to be derived in certain cases from smallpox 

 patients (Weiskopf), and in others from sheep pox (Roll). The 

 latter claims that the dog has also its own specific form. 

 Dupuis and others claim experimental transmission from man to 

 dog. At the .same time eruptions connected with gastric or 

 hepatic disorder, distemper, eczema, or aphthous fever are liable 

 to be mistaken for it. 



Symptoms. The young animals suffer from fever for a day or 

 two, followed by heat and redne.ss on the sides and belly, and 

 points of deeper red, like flea bites, which gradually evolve
