DISEASES OP THE BLOOD. 6l 



disease specially affects young dogs (under eighteen months 

 old), and very young animals almost always succumb to the 

 fever and prostration present, especially as in young 

 animals the disease passes through its several phases most 

 rapidly. 



Treatment consists in careful nursing of the patient, 

 disinfection, isolation, and, when necessary, stimulants, 

 vegetable tonics, and febrifuges. It is stated that in case 

 of recovery the animal is free from future attacks ; a pro- 

 perty of disease which has received the technical name of 

 " unidty." Heat is said to favour eruption and confluence 

 of the vesicles, whereas cold checks the eruption, and undue 

 exposure is almost sure to prove fatal to an affected animal. 



Glanders is communicable to the dog. Lafosse men- 

 tions a case where the animal became affected through 

 living in a stable with a glandered horse ; Polli induced 

 the disease in dogs by intravenous injection of disease 

 matter and spreading it on wounds ; Renault conveyed 

 it to dogs by inoculation from horses, and reinoculated 

 horses from these dogs successfully ; one third of the dogs 

 inoculated took the disease ; the infected dogs lived from 

 three and a half to five months. Hertwig failed to cause true 

 glanders by feeding dogs on the flesh of glandered horses, 

 although Nordstrom succeeded. St. Cyr found the 

 induced disease seldom fatal except when caused by intra- 

 venous injection, and he remarks that probably one attack 

 ensures future immunity, but this has not yet been estab- 

 lished. Chancres seldom appear on the nasal membrane in 

 the dog ; in Nordstrom' s cases there was bloody discharge 

 from the nostrils, oedema of the head, redness of the eyes, 

 and death, although generally spontaneous cure follows. 



Measles. — In 1876 a case was related before the Epi- 

 demiological Society where a dog (which four years before 

 suffered from distemper) licked the hand of a child suffer- 

 ing from severe measles. In twelve days' time the animal 

 sickened, a nasal discharge appeared on the second day, 

 and on the fourth day it died with marked congestion of 

 the throat and air-passages ('Veterinary Journal,' iii, p. 226) . 



Cholera has been supposed communicable to and by
