io8 DOGS 



PLEURISY. 



This is inflammation of the lining membrane of the chest and 

 frequently exists together with disease of the lung substance. 



Treatment. — The same as for inflammation of the lungs {see 

 page 107, par. 5). A veterinary surgeon should be called in. 



MANGE. 



Cause. — The mange mite or acarus. It is easily conveyed 

 from one dog to another, and from mats and furniture. 



Treatment. — Sulphur is a specific for true mange, but the 

 disease is often confounded with eczema {see Eczema, page 104). 

 Apply an ointment containing one part of sulphur to four 

 parts of lard and repeat every two or three days. A little 

 flowers of sulphur in the food is also desirable. 



FOLLICULAR MANGK 



This is the kind that does not spread rapidly all over a dog, 

 but is of slow development and is usually confined to the back, 

 extending from the poll to the root of the tail. 



Cause. — A parasite known as demodex follicidornm. Its 

 habits are such that it is not easily got at and destroyed. 



Treatment. — Wash the parts with soft soap and hot water, 

 and apply creosote one part, liquor of potass one part, olive oil 

 twelve parts. Repeat twice weekly. 



MOUTH CANKER. 



Causes. — Indigestion from injudicious feeding. Old age, 

 broken teeth. 



Treatment. — The canine dentist is required in such cases. 

 He can extract all the offending members and scale the others. 

 The mouth being rid of these, a few stomachic doses (as soda 

 and rhubarb) are all that is required beyond judicious dieting.
