By this singular name is distinguished a prevalent disease now about to come under our consideration, which was first observed on the continent. The rapidity with which it spread, the strange protean appearances which it assumed, and its too frequent fatal termination, surprised and puzzled the veterinary surgeons; and they called it "la maladie des chiens," the disease or distemper in dogs.
is comparatively a new disease. It was imported from France about one hundred years since, although some French authors have strangely affirmed that it is of British origin. Having once gained footing among us, it has established itself in our country, to the vexation and loss of the sportsman, and the annoyance of the veterinary surgeon. However keepers, or even men of education, may boast of their specifics, it is a sadly fatal disease, and destroys fully one-third of the canine race.
Dogs of all ages are subject to its attack. Many, nine and ten years old, have died of pure distemper; and I have seen puppies of only three weeks fall victims to it; but it oftenest appears between the sixth and twelfth month of the animal's life. If it occurs at an early period, it proves fatal in the great majority of cases; and, if the dog is more than four years old, it generally goes hard with him. It is undeniably highly contagious, yet it is frequently generated. In this it bears an analogy to mange, and to farcy and glanders in the horse.
One attack of the disease, and even a severe one, is no absolute security against its return; although the dog that has once laboured under distemper possesses a certain degree of immunity; or, if he is attacked a second time, the malady usually assumes a milder type. I have, however, known it occur three times in the same animal, and at last destroy him.
catarrh will often terminate in distemper; and low and insufficient feeding will produce it. It frequently follows mange, and especially if mercury has been used in the cure of the malady. When we see a puppy with mange, and that peculiar disease in which the skin becomes corrugated, and more especially if it is a spaniel, and pot-bellied or rickety, we generally say that we can cure the mange, but it will not be long before the animal dies of distemper; and so it happens in three cases out of four. Whatever debilitates the constitution predisposes it for the reception or the generation of distemper. It, however, frequently occurs without any apparent exciting cause.
it is highly contagious cannot admit of doubt. A healthy dog can seldom, for many days, be kept with another that labours under distemper without becoming affected; and the disease is communicated by the slightest momentary contact. There is, however, a great deal of caprice about this. I have more than once kept a dog in the foul-yard of my hospital for several successive weeks, and he has not become diseased. Inoculation with the matter that flows from the nose, either limpid or purulent, and in an early or advanced stage of the distemper, will, with few exceptions, produce the disease; yet I have failed to communicate it even by this method. Inoculation used to be recommended as producing a milder and less fatal disease. So far as my experience goes, the contrary has been the result.
