140 DISEASES OF THE GREYHOUND. 



say that I have had little opportunity of studying them, but of 

 late years I have seen and healed almost every variety. True 

 mange, being undoubtedly contagious, as well as most probably 

 hereditary, will sometimes intrude into the best-regulated kennels. 

 It is usually divided into the scabby and the red mange, but if 

 the subject were carefully studied, it would be found that there 

 are several distinct eruptions, which are confounded together 

 under the head of scabby mange. In one kind of the former, we 

 have an eruption which is most probably produced by a vegetation 

 similar to that found in the human scald head. In this form the 

 disease is highly contagious and not constitutional, and the erup- 

 tion consists of numerous pustules, at first distinct, but afterwards 

 coalescing, and forming one or more large scabs. The hair does 

 not at first fall of, but ultimately gets thin by degrees, until at 

 last it disappears. This eruption is very troublesome to cure, 

 and none but applications containing poisonous ingredients are 

 of the least benefit. Their use, therefore, is attended with 

 considerable danger to the dog, unless mixed with some article 

 which he will not lick ; but the itching is so violent, that he can 

 scarcely be prevented from biting himself, even by the most 

 disagreeable application. It is better to put on a muzzle of wire 

 or pierced leather, and to keep it on while the remedies are being 

 used, except at feeding time. The constitutional treatment should 

 depend on the state of the dog : if too high in condition, he 

 should be purged and kept low in diet ; and if, as is generally 

 the case, reduced in flesh and strength, then the contrary treat- 

 ment by tonics and nourishing diet should be tried. No applica-
