ENZOOTIC DISEASE IN DOGS— PNEUMONIA, WITH

EFFECTS OF QUINQUINA WINE, AND 
AN ANALEPTIC REGIMEN. 
By Professor RENAULT. 
ALTHOUGH we cannot attach the same importance to the study 
of the diseases of dogs as we do to that of the diseases of horses, 
sheep, and cattle, it is, nevertheless, not without considerable value, 
since veterinary surgeons are very frequently called in to attend 
on valuable or pet dogs. Sporting dogs are generally those for 
which their skill is required, being most valuable in every sense 
of the word. The owners of large kennels, or packs of sporting 
dogs, are often compelled to have recourse to the veterinary surgeon 
when the outbreak of some epidemic threatens the destruction of 
the greater part of these animals. Unfortunately, however, the 
canine epidemics have been hitherto so little studied, that even 
the very first landmarks are wanting to guide the veterinarian 
along this scarcely trodden path. He is, consequently, compelled 
to study while he should be acting, and thus is not only liable to 
mistake, but, while watching the disease in order to observe some 
symptom that may give him a clue to its character, he loses 
much valuable time, and finds it impossible to save his patients, 
especially as the epidemics usually run their course in an incre- 
dibly short period. These considerations, as well as their in- 
terest in a pathological point of view, have induced me to publish 
the following case, which is, I believe, without parallel in the 
annals of veterinary medicine. 
On the 10th of January, 1834, M. Schikler, having been informed 
that an enzootic had prevailed among his pack for several days, 
and that, out of seventy-two valuable dogs, four were already 
dead, and fifty-seven attacked by the disease, hastened to send to us 
for advice. The animals were at Glatigny, about three miles from
