Diseases of tJie Ear. 199 



paralysis of the auditory nerve from severe shock. Youatt 

 observes, with regard to cropping: "Deafness is occasion- 

 ally produced by it in some dogs, and constantly in others. 

 The frequent deafness of the pug is solely attributable 

 to the outrageous, as well as absurd, rounding of his ears. 

 The almost invariable deafness of the white, wire-haired 

 terrier is to be traced to this cause." 



Treatment. — If deafness proceed from congenital causes, 

 it is needless to remark that a cure is hopeless. Where it is 

 due to morbid growths, resulting from canker, polypus, or 

 other diseases, the removal of such obstruction is indicated. 

 If from paralysis, counter-irritation behind the ears, by 

 blisters or seton, and the administration of strychnine or 

 nux vomica, are the measures to be adopted. 



SCURFY EARS. 



Scurfy ears are frequently met with in long-haired dogs, 

 and may either be associated with mange, or the result of 

 an over-heated, plethoric habit of body — more frequently 

 the latter. If neglected, this condition is apt to run on to 

 canker. 



Treatment. — An aperient, followed by drachm doses of 

 sulphur in a bolus daily, and a spare, unstimulating diet, 

 usually removes the affection. An ointment composed of 

 sulphur and whale-oil may, in obstinate cases, be applied, 

 with success to the ears.
