CONTAGIOUS DISEASES OF DOGS. 613 



run from 120 to 160, with elevated temperature. Frequently 

 an opacity spreads OA'er the cornea, quickly succeeded by ulcera- 

 tion. The first of the ulceration is generally seen in the center 

 of the cornea, and is circular. The ulcer widens and deepens; 

 sometimes it eats through the cornea, and the aqueous humor 

 escapes. As the disease advances, the dog becomes so feeble at 

 the end of a week that it can scarcely stand. The appetite is al- 

 most entirely lost. Food is quickly vomited or passes through the 

 intestinal canal in a fetid, ill-congested condition. At the end of 

 a fortnight the symptoms may abate in intensity and the dog 

 slowly regain its strength. Sometimes epileptic fits come on, 

 making a serious complication. If a second fit come on within a 

 day or two the dog is generally lost. These fits may appear with- 

 out warning; if their approach be carefully watched, they may 

 possibly be prevented. The champiug of the lower jaw will be 

 seen at least twelve hours before the first fit. 



The inflammation extends to the lungs in some cases, pro- 

 ducing pneumonia. If the ear be placed to the chest, the crepi- 

 tating sounds of pneumonia will be detected. Intestinal compli- 

 cations are indicated by violent vomiting and purging. The 

 fax-es vary from white, with a slight tinge of gray, to a dark slate 

 color. By degrees mucus begins to mingle with the fsecal dis- 

 charge, and then streaks of blood. The case when in this condi- 

 tion is almost hopeless. Jaundice is a frequent complication. 

 An intense yellowness suddenly appears all over the dog. The 

 result of this complication is usually unfavorable. In most in- 

 stances cutaneous eruptions are seen on the inner surface of the 

 thighs and other parts where the hair is thin and downy. These 

 eruptions peel off in large scales, causing the hair to be filled 

 vith them. 



Treatment. — In the early stages, if the bowels are at all irreg- 

 ular, a small dose of castor oil is to be prescribed. The dose 

 varies from a teaspoonful for a young puppy to an ounce for a 

 well-grown dog. After the purgative acts I have received the 

 best results from sal. acetate of ammonia, four drachms; nitrous
