nteritis is rarely seen in a pure form. The mucous
membrane of the intestines is mostly inflamed, but the serous covering, as
a general rule, is in no degree involved. The stomach, however, is almost
in every instance more or less implicated; its inner surface being
inflamed, and its muscular coat so contracted, that the lining membrane is
corrugated, and remains in that condition after death.

The incentives are, unwholesome food, which is the most frequent of the
causes; exposure, especially after a dog has been in winter fantastically
deprived of its long hair over the loins; and over-exertion, to which the
dog is often exposed, no attention being paid to its condition. Anything
which disorders the digestion, or violently shakes the constitution, will
induce it; for in the dog every species of revulsion has a tendency to
attack the bowels. Mange improperly treated has produced it; and this may
be said of almost any skin disease; so that it has been caused not by true
mange or itch alone but by a skin disease having been, under the pretence
of working an immediate cure, driven into the system. Neglected
impactments, or colic, are among its most frequent immediate causes; for
at least three parts of those cases of enteritis submitted to my notice,
have been clearly traced to have commenced with something of that kind.

Of the symptoms of enteritis, colic and constipation, with a hard thin
pulse, are the most prominent. Sickness is not present, or rather I have
not witnessed it, at the commencement of the disorder. The extremities are
cold--the eye has a stupid expression, the pupil being much dilated--the
breath is hot, and the nose dry. The tail is drawn firmly downward, and
pressed upon the anus; the urine is sometimes scanty, always high-colored;
the tongue is rough and clammy, the thirst strong, and the appetite lost.
The dog seeks darkness and privacy, and does not ramble during the early
stage; it will stretch itself out either upon its belly or on its side,
and I have not seen it sit upon its haunches. The abdomen is only of the
heat of the body, which is generally of an increased temperature. Pressure
appears to cause no pain, and the animal rather seems grateful for
friction than to resist it. As the disease proceeds, diarrhoea ensues, and
with it the signs of exhaustion and death generally are exhibited.
Throughout the attack there is a marked disinclination to take any remedy;
which is not always displayed by
