VERTIGO. 



Dogs are occasionally seized with a kind of dizziness or 

 vertigo. They suddenly fall, remain unconscious for a 

 minute or two, and motionless ; and then almost as 

 suddenly regain their legs, and with the exception of 

 appearing a little bewildered, seem as though nothing 

 unusual had happened. 



Such seizures are generally due to brain pressure, most 

 frequently from some retarding influence in the return ot 

 blood from the head, as a tight collar, glandular enlarge- 

 ments, bronchocele, etc. A disordered condition of 

 stomach is likewise a predisposing cause, and the suscepti- 

 bility to an attack of vertigo is greater after a full meal, 

 and particularly if any of the above-named obstructions to 

 the circulation also exist. 



Treatment. — This consists in removal of the cause ; neck 

 pressure as far as possible should be avoided ; a healthy 

 state of the digestive organs maintained, with proper ob- 

 servance of hygienics. 



CHOREA. 



Chorea, or St. Vitus's dance, is a purely nervous affec- 

 tion, and is the, result generally of an irritable and impaired 

 condition of the nervous system. It may be general or 

 local. The limbs are frequently first observed affected, 

 ultimately the body, face, and jaws may be involved, the 

 latter exhibiting tetanic symptoms.* 



Symptoms. — Chorea is denoted by a peculiar snatching 

 or twitching of the part affected. If the brain is involved,

 tensively afflicted with chorea ; the jaw can only be opened half an 

 inch, and goes to again with a sharp snap. The lips are convulsed.
