The Teeth are subject to disorder and discoloration 
from accumulations of so-called tartar at the neck, 
producing also irritation of the gums and the tooth 
cavity, usually ending in caries or displacement of the 
teeth and ulceration of the gums. The subjects are the 
well fed and pampered pets, especially old dogs, which 
contract a chronic form of dyspepsia, accompanied by 
offensive breath, flow of saliva from the lips, pain and 
inconvenience, until the animal becomes “broken 
mouthed ”—that is, having scarcely a sound tooth. 
To prevent these conditions the dog should be allowed 
to use and clean his teeth in the natural manner, namely, 
the picking of bones and other food sufficiently solid to 
require breaking down. For this purpose the Fibrine 
Cakes of Spratt’s Patent are highly useful. 
Broken Teeth are the result of carrying hard or 
heavy articles. Displacement is the result of irregular 
growth or accumulation of tartar, absorption of the 
alveolar margins, and ulceration of the gums. Extraction, 
with the after observance of hygienic rules, are the means 
of remedy. 
Caries of the Teeth is the result of indigestion and 
improper feeding, probably derived from hereditary 
predisposition or taint. Breeders should especially note 
this fact. Excessive foetor, unusual salivation, dulness,
