206 MANGE. 



meet every variety. They are proved by long" experience, 

 and a succesbfiil practice. Tobacco water is often used for the 

 cure of this complaint, and, in very sh'g-ht cases, it frequently 

 does some g^ood ; but, unless used with extreme caution, it is 

 a most dang-erous remedy, from the tendency all dogs have to- 

 lick themselves ; and when they do this with tobacco, the 

 effects are often fatal. I have myself seen several poisoned 

 by these means. Great caution is also requisite, for the same 

 reasons, with all kinds of washes in which there is any thing" 

 active, as mercurials, &c. It is also a common practice to 

 dip mang^y dog's in the tanners' pits; but it is a very filthy, 

 and not often an efficacious, one, except in very slight cases: 

 in such instances, an infusion of oak bark, with a little alum, 

 would of course do as well. 



Having detailed the outward applications, it becotnes ne- 

 cessary to mention the internal ones that are required. 

 When mang-e is generated, the constitution must be at fault 

 to produce it ; and, when it is taken, it will itself affect the 

 constitution : so that in all, except very slight cases indeed^, 

 some internal remedies are requisite. In very full habits, and 

 particularly in red mange, bleeding is very proper *. I have 

 also, in some instances, experienced benefit from a seton 

 placed in the neck as a counter drain, particularly when the 

 head has been much affected. It is also very requisite to at- 

 tend particularly to the food : whatever has been injudicious, 

 both as to quantity and quality, should be altered. Fre- 

 quently a total change in the manner and matter of feeding- 

 assists the cure very materially.— 8ee the subject o/Feeding. 



Purges, when regularly administered, often prove very use- 

 ful ; for which purpose Epsom salts may be given, two or 

 three times a week, in mild doses. But the most effectual 

 internal remedy is a judicious use of alteratives. Red mang-e 



* In the Philosophical Transactions, No. xxv, p. 451, is detailed a 

 case of a mangy dog successfully treated by transfusing into liim the 

 l)lood from a healthy dog. How far a similar result would follow i?s 

 other cases is doubtful.
