Chorea or St Vitus' s Dance 



This is a nervo-muscular trouble, extremely 

 common as a sequel to distemper, often developing 

 during the convalescent stage. It is an affliction 

 that varies greatly in its severity, some dogs having 

 the complaint so slight that the owner may not be 

 aware of its existence. On the other hand it is of 

 so great severity as to necessitate the destruction of 

 the hound. No true pathological knowledge has 

 been ascertained up to the present time. Chorea is 

 characterized by involuntary muscular twitchings, 

 especially about the face and the limbs. These move- 

 ments are sometimes in abeyance during sleep. In 

 slight cases recovery sometimes occurs, but medicinal 

 treatment does very little good.
