BRONCHITIS.

Dogs that have been exposed to wet, or that have been put to lie in a
damp or draughty kennel with insufficient food, are not less liable
than their masters to catch a severe cold, which, if not promptly
attended to, may extend downward to the lining membranes of bronchi or
lungs. In such cases there is always symptoms more or less of fever,
with fits of shivering and thirst, accompanied with dullness, a tired
appearance and loss of appetite. The breath is short, inspirations
painful, and there is a rattling of mucus in chest or throat. The most
prominent symptom, perhaps, is the frequent cough. It is at first dry,
ringing, and evidently painful; in a few days, however, or sooner, it
softens, and there is a discharge of frothy mucus with it, and, in the
latter stages, of pus and ropy mucus.

_Treatment_--Keep the patient in a comfortable, well-ventilated
apartment, with free access in and out if the weather be dry. Let the
bowels be freely acted upon to begin with, but no weakening discharge
from the bowels must be kept up. After the bowels have been moved we
should commence the exhibition of small doses of tartar emetic with
squills and opium thrice a day. If the cough is very troublesome, give
this mixture: Tincture of squills, 5 drops to 30; paregoric, 10 drops
to 60; tartar emetic, one-sixteenth of a grain to 1 grain; syrup and
water a sufficiency. Thrice daily.

We may give a full dose of opium every night. In mild cases carbonate
of ammonia may be tried; it often does good, the dose being from two
grains to ten in camphor water, or even plain water.

The chronic form of bronchitis will always yield, if the dog is young,
to careful feeding, moderate exercise, and the exhibition of cod-liver
oil with a mild iron tonic. The exercise, however, must be moderate,
and the dog kept from the water. A few drops to a teaspoonful of
paregoric, given at night, will do good, and the bowels should be kept
regular, and a simple laxative pill given now and then.

DIARRHOEA,

or looseness of the bowels, or purging, is a very common disease among
dogs of all ages and breeds. It is, nevertheless, more common among
puppies about three or four months old, and among dogs who have
reached the age of from seven to ten years. It is often symptomatic of
other ailments.

_Causes_--Very numerous. In weakly dogs exposure alone will produce
it. The weather, too, has no doubt much to do with the production of
diarrhoea. In
