ON TIIE DISEASES OF DOGS. 
affections of the mucous membranes of the respiratory passages 
may be recognized by the general heat of the skin in the neigh- 
bourhood of these parts, by the whitish fur which covers the sur- 
face of the tongue, and the redness of the edges and the point of 
this latter organ ; also, by the foetidity of the breath, the nausea, a 
distaste for every kind of food, and sometimes absolute sickness. 
When the irritation is extended to the internal intestinal mem- 
brane and becomes very intense, miliary eruptions appear on vari- 
ous parts of the bod}', particularly where the skin is thinnest, as 
under the legs and thighs. 
These complications with gastritis and entero-gastritis may be 
dependent on the action of the cause which induced the disease, or 
on a sympathetic participation of the mucous membranes of the 
former passages in a morbid state, or on the inconsiderate use of 
exciting medicines. 
Where irritation of the gastro-intestinal passages exists, it is 
not uncommon to see the animals troubled with worms. It will 
then withdraw itself from notice, seek quiet and obscurity, appear 
dull and peevish, bite on the slightest provocation, and, in short, 
offer all those symptoms which are described by most authors as 
appertaining to dumb madness. 
A complication with irritation of the urinary passages is indicated 
by all these signs, which usually announce a catarrhal state of those 
parts, and also by the appearance of the urine, which becomes 
yellow, and exhales an unpleasant, infectious smell. 
Nasal catarrh in dogs, and especially in young animals, is often 
complicated with cerebral affection, when a sanguineous congestion 
of the brain not unfrequently results. In this case the animal ap- 
pears in a species of coma; he is dull, stupid, lazy, inattentive, and 
lies down almost constantly ; his senses appear obtuse ; occasional 
shiverings are observable, and the skin is very hot. Sometimes 
the animal is excited almost to vertigo — it appears strangely un- 
easy; it runs about without aim or end, backwards and forwards; 
the pupil is dilated, it neither sees, hears, nor understands. This 
state soon becomes aggravated, and the sufferings acute. The ani- 
mal cries almost incessantly, lies down, is restless, convulsed, and 
dies on the fourth or fifth day, without having vomited at all, or had 
more than a very slight flow of matter from the nose.
