SMALL-POX IN THE DOG.

riola in the dog, and I have only found that which Barrier writes 
in the “ Instructions Veterinaires” for 1791*. 
* The following is the Essay to which M. Leblanc refers. It is entitled 
“ Small Pox in the Dog” by M. Barrier, M.V. k Chartres. 
Man, the sheep, the rabbit, and the ox, are not the only animals subject to 
the disease termed small-pox in the first, and claveau in the others. The dog 
is also exposed to it, and I have had the opportunity of observing it three dif- 
ferent times. The following are the symptoms which presented themselves, 
and the treatment which I adopted. 
On the first day the dog is dull, he carries his head and his tail low — his 
eyes are half closed — his muzzle ishotunddry — his tongue is coated, and his 
breath tainted — his pace is slow and staggering — he lies down continually, 
and can scarcely be induced to rise— he frequently vomits — he is constipated 
— his urine is high-coloured — his coat stares, and the hair readily falls ofif — 
his pulse is hard and frequent — and he is altogether changed in his appear- 
ance. 
On the second day he passes much bilious matter by stool — his evacuations 
are dark, and very foetid, or if the constipation continues to the third day, 
then comes diarrhoea, which cannot be stopped for two or three days. The 
animal is now evidently very ill, the countenance betraying his uneasiness and 
anxiety. He seeks for a cold situation — he leaves his bed, and stretches him- 
self on the pavement. A perspiration, seldom seen in the dog, breaks out 
abundantly, and wets the place on which he lies. 
Towards the fourth day, shivering fits come upon him. His hair, especially 
about the head, stands upright, and on that or the following day the head 
becomes covered with pustules. They spread over every other part except 
the back and sides, where there are, comparatively, few ; but they are found 
on the lips, the muzzle, the eyelids, the vulva, the anus, the prepuce, and be- 
tween the toes. The animal walks with difficulty, and cries as he walks. 
These pustules are precisely those of small-pox, or claveau. They are first 
red, then white; then they suppurate, and dry, and fall ofif. 
The eruption is characterized, as in sheep, by its mildness or its confluent 
form. In the first, a hound four years old, it was nine days before it was 
fully out. In the second, a wolf-dog, whose health was scarcely affected by 
it, it quickly appeared, and as quickly dried away. In the third, a Danish 
dog of four months, it was not fully out until the eighteenth day, and then 
it was confluent. 
These animals were kept on broth and milk. Vinegar and camphor were 
administered, but then the milk was omitted — injections of broth and vine- 
gar were thrown up — nitre was sometimes given — and a purgative when the 
scabs began to fall off. 
M. Barrier adds, that this is not the only case of small-pox in dogs. “ Les 
Ephemerides d’Allernagne” make mention of a dog that caught it from a 
person with whom he slept, and M. Huzard relates the following fact : — 
Some sheep died of the clavelde, and were left in a ditch. A pack of hounds 
passing, began to devour the carcasses ; and seventeen of them became ill. 
It was at first thought to be the distemper, because they lost they spirits, 
became weak, paralytic in the loins, and discharged from the nostrils a viscid 
and green humour : but a plentiful crop of inflammatory pustules soon ap- 
peared, and proved the disease to be malignant small-pox. Eleven of them 
died, and the helper at the kennel fell ill, and had his hands and face covered 
with pustules. 
M. Barrier then speaks of a monkey who caught the small-pox from some 
children with whom he was accustomed to play; and of another who caught 
the measles from a child on whose bed it was accustomed to lie. It had all
