34 KENNEL DISEASES. 
result from the inhalation of irritants, as dust, smoke, fumes from chemicals, 
etc. ; and occurring as it does in epidemics, and being often contagious and con- 
veyed from one to another, it is certainly reasonable to infer that it is at times of 
microbic origin. 
In ordinary cases the earliest symptoms of the affection are watery dis- 
charges from the nose, with evident obstruction to breathing through it, sneezing, 
and redness of the eyes, which are also watery. Dogs presenting these signs 
wipe their nose with their paws, and are usually somewhat languid, and not inclined 
to eat nearly as much as usual. They may also have slight fever, but the temper- 
ature is seldom more than one or two degrees above the normal in this affection 
alone. Nor is there considerable quickening of the pulse. Finally, there occurs 
the more or less abundant muco-purulent discharge, and recovery has commenced. 
When produced by the teenia-like parasite the symptoms are somewhat modi- 
fied. In simple coryza due to other causes there is but rarely indeed any bleed- 
ing at the nose; but when the parasite is present, the nasal discharge is more or 
less bloody. It contains more purulent matter, and has a very offensive odor. 
The general system also is more disturbed in such cases; and it is even possible 
for the inflammation caused by the parasite to extend and involve the coverings 
of the brain, and so terminate fatally. The symptoms then are those of acute 
meningitis ; or there may appear a tendency to snap and bite, as in rabies. To 
add to the resemblance of the symptoms of that malady, paralysis of the lower 
jaw may occur, as in the dumb form. 
The natural tendency of the ordinary inflammation in the nose is to extend 
down the throat and into the bronchial tubes. On reaching the former it is 
pharyngitis and laryngitis, and in the latter bronchitis; all of which will be duly 
discussed elsewhere. F 
Coryza alone and uncomplicated is not a common disease in mature dogs, for 
it usually merges into bronchitis ; but very young puppies are quite frequently vic- 
tims of it, and with them it almost always runs its course and ends as such, — 
that is, the inflammation is confined throughout to the nose. 
Frequently occurring attacks of acute coryza might produce the chronic form, 
commonly termed chronic nasal catarrh, that is also sometimes found in old dogs 
whose lungs are unsound, and consequently their systems are steadily breaking 
down. Other cases justify the belief that this chronic trouble is sometimes caused 
by a peculiar germ. 
In ordinary attacks of coryza, to give a purge as soon as the first symptoms 
appear, feed lightly for a week, and keep the patient in comfortable quarters, is 
the treatment advisable for older puppies and mature dogs; and it will generally 
suffice. If, however, the attacks are very intense, and the victims seem quite ill, 
the following might be obtained: Sulphate of quinine, three grains; fluid ex- 
tract of belladonna, two minims; salicylate of sodium, thirty grains; camphor, 
three grains. When the patient is of medium or largest-size breed this mixture
