200 THE MANAGEMENT AND DISEASES OF THE DOG. 



pimples makes their appearance, which rapidly become pus- 

 tular, break, and exude serum, or, in severe cases, pus. The 

 matter thus exuded forms scabs, or crusts — the skin is thick- 

 ened and chapped as in common mange. 



The itching attendant on follicular mange is not excessive 

 nor continuous. The disease usually commences on the head, 

 and from thence extends to the body ; it is of long duration, 

 and very obstinately yields to treatment. 



Detached hair is rarely replaced, owing to the destruc- 

 tion of the hair follicle. 



Treatment. — The difficulty experieneed in reaching the 

 acari renders curative measures somewhat troublesome and 

 unsatisfactory. Mercurial agents are, perhaps, the most use- 

 ful. White precipitate, combined with sulphur and whale-oil, 

 is a very excellent formula. 



The following ointment (my own prescription) has been in 

 my practice attended with the best results in cases of follicu- 

 lar mange.

The whole to be well mixed, and rubbed on the affected 

 parts for five minutes. Wash off in forty-eight hours with 

 soft-soap and warm water, and when the skin is dry apply to 

 the surface whale-oil ; and the following day, without wash- 

 ing, repeat as before the ointment-dressing. Allow a week 

 to elapse before another dressing of the same, if necessary, is 

 applied. Ift recent cases a third application is not often re- 

 quired. After each dressing, the kennel should be thoroughly 

 cleansed- and disinfected before the dog is suffered to inhabit 

 it. All wood and iron-work should be well scoured with boil- 

 ing water and soda, and to any brick-work, after first brushing, 

 limewash with carbolic acid should be applied.
