4 GO DISEASES OF THE SKIN 



of eczema. More rarely it is found following distemper. It appears 

 1)ehind the ears, on the neck, and at the root of the tail, from which 

 locations it may gradually extend. The animals give off a slightly 

 rancid or foetid odor and are slightly itchy in the early stages. There 

 may be a bran-like dandruff which increases in amount, later accompanied 

 by desquamation of the external epithelium. The hair feels oily and 

 unhealthy, imparting to the hand a peculiar, foetid, unpleasant odor, 

 characteristic of this disease. The hair gradually falls out, and the 

 animal becomes bald. The treatment consists in bathing with strong 

 sulphur soap, or soaps containing benzoin, and the application of sali- 

 cylic and sulphur ointments. 



Seborrhoea Oleosa. — This appears, as a rule, in the parts having the 

 most hair, yet it may also be observed in the crural surface and folds. 

 It frec{uently develops after distemper and is sometimes observed as a 

 result of the irritation caused by acari. The skin feels as if it were 

 oiled, and leaves the hand oily after having stroked the animal. Want 

 of cleanliness may occasionally produce a modification of this condition. 



Seborrhoea praeputi has been described by Schindelka as appear- 

 ing in dogs with very narrow contracted foreskins, and has no similarity 

 or connection with phimosis. The preputial orifice continually dis- 

 charges a foetid, oily-like fluid, greenish in color, and has much more 

 consistency than the discharge in blenorrhcea of the prepuce. The 

 treatment consists in cleansing of the penis with an antiseptic soap and 

 followed by dusting the affected parts with dermatol powder. If phi- 

 mosis is present, the opening must be enlarged by an incision. 



Pemphigus. — This appears in man as a result of a number of diseases, 

 and is indicated by the appearance of a series of vesicles which reappear 

 from time to time and are apt to become chronic. In one case observed 

 by Frohner, a male poodle dog not yet a year old gradually lost flesh 

 and became ansemic. His back and both sides of the body up to the 

 scapula, as well as the upper part of the legs, were denuded of hair, and 

 certain raw spots on the skin about 2 mm. deep, varying in size. They 

 w'ere light rose-red on the border, shiny red in the centre, smooth, glossy 

 and slightly moist on the surface. On the neck and upper sections of the 

 anterior limbs were a number of vesicles the size of a hazelnut covered 

 with dirty brownish-green crusts. These vesicles gave out, when 

 pressed, a yellowish-white pus. The head, tail and posterior parts of 

 the legs were free from vesicles or spots. The appetite was very good, 

 but the animal grew weaker and weaker, and finally was destroyed. 



Impetigo. — This is a condition understood as an eruption of pus 

 vesicles. It is noticed frequently in distemper, and has been observed 

 in old bitches in an advanced state of gestation. Some of them are also 

 afflicted with endometritis.
