APOPLEXY. 225 
The oxide of zinc is a more potent remedy for nervousness and nervous 
affections than this, and it might be given twice daily. The dose for a dog of 
medium size is two grains; for largest breeds, three grains ; for small breeds, as 
fox-terriers, one grain ; and for toys, one-half a grain. 
To have any marked effect, in nervous cases the zinc must be given regularly 
for a month or more. 
VERTIGO. 
Vertigo, dizziness and giddiness, is an occasional symptom among dogs. 
Occurring in man, sometimes his own head seems to be turning around, while at 
other times everything in sight appears to turn instead. 
When a dog suffers from an attack, it is as a rule immediately after he has 
been lying down. He starts up as usual, but stops while rising, then slowly lifts 
himself, as it were, onto his feet, with difficulty and hesitation. Once on all 
fours he takes a few steps, but reels like one intoxicated, and spreads his legs 
apart to prevent falling. He also closes his eyes for a moment, and likely there 
are a few slight twitchings of the head, which may sway to the side. For per- 
haps half a minute he seems afraid to move ; then suddenly shakes himself, and 
generally starts off as usual; although sometimes vomiting first occurs. 
The most common cause of vertigo is indigestion, accompanied by a disturb- 
ance of the liver which may come under the head of “biliousness.” It may be 
associated with trouble in the internal ear, also occur as a symptom of general 
debility, and more often of brain affection. A collar so tight that it interferes 
with circulation, and consequently causes congestion of the head, may induce an 
attack. 
Manifestly the removal of the cause is the all-important requirement in treat- 
ment; and this is effected in most cases by a generous dose of Epsom salts, 
castor-oil, or a mixture of the syrup of buckthorn and sweet-oil. Although other 
medicines may be needed in a small proportion of cases, correct feeding, judi- 
cious exercise, and better management all around will generally suffice to effect 
a cure after the bowels have been well swept out by the cathartic. 
APOPLEXY. 
The term apoplexy signifies a sudden attack, characterized by loss of con- 
sciousness and profound stupor; and the same is commonly called a stroke or 
shock. 
It is usually abrupt in its occurrence; and while the victim may seem to retain
