short an attack. The oil is preferable to rhubarb,
but the latter may be tried--the simple, not the compound powder--dose
from 10 grains to 2 drachms in bolus.

It the diarrhoea should continue next day, proceed cautiously--remember
there is no great hurry, and a sudden check to diarrhoea is at times
dangerous--to administer dog doses of the aromatic chalk and opium
powder, or give the following medicine three times a day: Compound
powdered catechu, 1 grain to 10; powdered chalk with opium, 3 grains
to 30. Mix. If the diarrhoea still continues, good may accrue from a
trial of the following mixture: Laudanum, 5 to 30 drops; dilute
sulphuric acid, 2 to 15 drops; in camphor water.

This after every liquid motion, or, if the motions may not be observed,
three times a day. If blood should appear in the stools give the
following: Kino powder, 1 to 10 grains; powder ipecac., 1/4 to 3
grains; powdered opium 1/2 to 2 grains. This may be made into a bolus
with any simple extract, and given three times a day.

The food is of importance. The diet should be changed; the food
requires to be of a non-stimulating kind, no meat being allowed, but
milk and bread, sago, or arrowroot or rice, etc. The drink either pure
water, with a pinch or two of chlorate and nitrate of potash in it, or
patent barley-water if the dog will take it.

The bed must be warm and clean, and free from draughts, and, in all
cases of diarrhoea, one cannot be too particular with the cleanliness
and disinfection of the kennels.

CONSTIPATION,

more commonly called costiveness, is also a very common complaint. It
often occurs in the progress of other diseases, but is just as often a
separate ailment.

Perhaps no complaint to which our canine friends are liable is less
understood by the non-professional dog doctor and by dog owners
themselves. Often caused by weakness in the coats of the intestine.
_The exhibition of purgatives can only have a temporary effect in
relieving the symptoms_, and is certain to be followed by reaction,
and consequently by further debility. Want of exercise and bath common
cause.

Youatt was never more correct in his life than when he said: "Many
dogs have a dry constipated habit, often greatly increased by the
bones on which they are fed. This favours the disposition to mange,
etc. It produces indigestion, encourages worms, blackens the teeth,
and causes fetid breath."

_Symptoms_--The stools are hard, usually in large round bal
