The sudden appearance of redness of the skin, and exudation from it, and actual sores attending the falling off of the hair, and itching, that seemed to be intolerable, have also been prevalent to an unprecedented extent. This mange, however, is to a certain degree manageable. A dose or two of physic should he given, with an application of a calamine powder, and the administration of the iodide of potassium.
Mr. Blaine gives a most valuable account of mange in the dog, part of which I shall quote somewhat at length. Mange exerts a morbid constitutional action on the skin; it is infectious from various miasmata, and it is contagious from personal communication. In some animals it may be produced by momentary contact; it descends to other animals of various descriptions; there is no doubt that it is occasionally hereditary: it is generated by effluvia of many various kinds; almost every kind of rancid or stimulating food is the parent of it. High living with little exercise is a frequent cause of it, and the near approach of starvation is not unfavorable to it. The scabby mange is the common form under which it generally appears. In red mange the whole integument is in a state of acute inflammation; surfeit, or blotches, a kind of cuticular eruption breaks out on particular parts of the body without the slightest notice, and, worse than all, a direct febrile attack, with swelling and ulceration, occurs, under which the dog evidently suffers peculiar heat and pain. Last of all comes local mange. Almost every eruptive disease, whether arising from the eye, the ear, the scrotum, or the feet, is injurious to the quality as well as the health of every sporting dog: the scent invariably becomes diseased, and the general powers are impaired.
There are several accounts of persons who, having handled mangy dogs, have been affected with an eruption very similar to the mange. A gentleman and his wife who had been in the habit of fondling a mangy pug dog, were almost covered with an eruption resembling mange. Several of my servants in the dog-hospital have experienced a similar attack; and the disease was once communicated to a horse by a cat that was accustomed to lie on his back as he stood in the stall.

These are often unpleasant things to have to do with. A Newfoundland dog had the whole of the inside of his mouth lined with warts. I applied the following caustic: —

. The warts were touched twice every day, and in less than a fortnight they had all disappeared.
Another dog had its mouth filled with warts, and the above solution was applied. In four days considerable salivation came on, and lasted a week, but at the expiration of that time the warts had vanished. The owner of the dog had applied the solution with the tip of her finger; she experienced some salivation, which she attributed to this cause.
The skin of the dog, from the feebleness of its perspiratory functions, is little sensible to the influence of diaphoretics: therefore we trust so much to external applications for the cure of diseases of the skin of that animal.

This is a disease too frequent among females of the dog tribe, and occasionally seen in the male. Its symptoms, local and general, are various. They are usually very obscure in their commencement; they increase without any limit; they are exasperated by irritants of any kind; and in the majority of cases their reproduction is almost constant, and perfectly incurable.
With
regard to the female, it is mostly connected with the secretion of milk. Two or three years may pass, and at almost every return of the period of œstrum, there will be some degree of enlargement or inflammation of the teats. Some degree of fever also appears; but, after a few weeks have passed away, and one or two physic balls have been administered, everything goes on well. In process of time, however, the period of œstrum is attended by a greater degree of fever and enlargement of the teats, and at length some diminutive hardened nuclei, not exceeding in size the tip of a finger, are felt within one of the teats. By degrees they increase in size; they become hard, hot, and tender. A considerable degree of redness begins to appear. Some small enlargements are visible. The animal evidently exhibits considerable pain when these enlargements are pressed upon. They rapidly increase, they become more hot and red, various shining protuberances appear about the projection, and at length the tumour ulcerates. A considerable degree of sanious matter flows from the aperture.
The
tumours, however, after a while diminish in size; the heat and redness diminish; the ulcer partly or entirely closes, but, after a while, and especially when the next period of œstrum arrives, the tumour again increases, and with far greater rapidity than before, and then comes the necessity of the removal of the tumour, or if not, the destruction of the animal. In the great majority of cases, the removal of the cancer does not destroy the dog, but lessens its torture. The knife and the forceps must usually be resorted to, and in the hands of a skilful surgeon the life of the animal will be saved.
When the cancer is attached to the neighbouring parts by cellular substance alone, no difficulty will be experienced in detaching the whole of it. The operation will be speedily performed, and there will be an end of the matter; but, if the tumour has been neglected, and the muscular, the cellular, or even the superficial parts have been attacked, the utmost caution is requisite that every diseased portion shall be removed. Mr. Blaine adds to this that
"it must also be taken into the account, that, although in the canine cancer ulceration does not often reappear in the intermediate part, when the operation has been judiciously performed, yet, when the constitution has been long affected with this ulcerative action, it is very apt to show itself in some neighbouring part soon after."

In the month of March, 1836, a valuable pointer dog was sent to
Mr. Adam
of Beaufort, quite emaciated, with total loss of appetite and with a large fungus hæmatodes about the middle of the right side of his neck. It had begun to appear about five months before, and was not at first larger than a pea. Mr. Adam gave him a purgative of Barbadoes aloes, which caused the discharge of much fetid matter from the intestines. At the expiration of three days he removed the tumour with the knife. There was a full discharge of healthy matter from the wound. During the period of its healing the animal was well fed, and ferruginous tonics were given. In a little more than three weeks the wound had completely filled up with healthy granulations, and the dog was sent home to all appearance quite well.
At the expiration of three months another tumour made its appearance near the situation of the former one, growing fast; it had attained nearly the size of the other. Mr. Adam removed it immediately, ordering a system of nutritive feeding and tonics. It appeared at first to go on favourable; but, five days after the removal of the second one, a third made its appearance.
This was removed at the expiration of another five days; but the animal was totally unable to walk, with very laborious breathing and cold extremities. A cathartic was given and the legs bandaged; but the wounds made no progress towards healing, and at the end of three days he died. On exposing the cavity of the thorax it was almost covered with variously formed tumours, from the size of a pigeon's egg to that of a small pea. The intercostal muscles had many of these adhering to them, and a few small ones were developed on the heart. There were three on the diaphragm, in the centre of which matter was formed. The blood-vessels, kidneys, &c., were free from disease. These tumours were white, or nearly so, rather hard, and of a glandular substance. The external ones were soft, red, and almost destitute of blood-vessels, except the first, which bled considerably. There was dropsy of the abdomen.

Sore feet constitute a frequent and troublesome complaint. It consists of inflammation of the vascular substance, between the epidermis and the parts beneath. It is the result of numerous slight contusions, produced by long travelling in dry weather, or hunting over a hard and rough country, or one covered with frost and snow. The irritation with which it commences continues to increase and a certain portion of fluid is determined to the feet, and tubercles are formed, hard, hot, and tender, until the whole foot is in a diseased state, considerably enlarged. The animal sadly suffers, and is scarcely able to stand up for a minute. Sometimes the ardour of the chase will make him for a while forget all this; but on his return, and when he endeavours to repose himself, it is with difficulty that he can be got up again. The toes become enlarged, the skin red and tender, and the horny sole becomes detached and drops. Local fever, and that to a considerable extent, becomes established; it reacts on the general economy of the animal, who scarcely moves from his bed, and at length refuses all food. At other times a separation takes place between the dermis and the epidermis, which is a perfect mass of serosity.
Still, however, it is only when all this has much increased, or has been neglected, that any permanently dangerous consequences take place. When violent inflammation has set in, the feet must be carefully attended to, or the dog may be lamed for life. One or two physic-balls may be given; all salted meat should be removed, and the animal supplied with food without being compelled to move from his bed. The feet should be bathed with warm water, and a poultice of linseed meal applied to them twice in the day. If, as is too often the case, he should tear this off, the feet should be often fomented. It is bad practice in any master of dogs to suffer them to be at all neglected when there are any tokens of inflammation of the feet. The neglect of even a few days may render a dog a cripple for life. If there are evident appearances of pus collecting about the claws, or any part of the feet, the abscess should be opened, well bathed with warm water, and friar's balsam applied to the feet.
When the feet have been neglected, the nail is apt to grow very rapidly, and curve round and penetrate into the foot. The forceps should he applied, and the claws reduced to their proper size.
If there are any indications of fever, or if the dog should be continually lying down, or he should hold up his feet, and keep them apart as much as he can, scarifications or poultices, or both, should be resorted to.
When the feet of a dog become sore in travelling, the foolish habit of washing them with brine should never be permitted, although it is very commonly resorted to. Warm fomentations, or warm pot-liquor, or poultices of linseed meal should be applied, or, if matter is apparently forming, the lancet may be resorted to.
Dogs
are frequently sent to the hospital with considerable redness between the toes, and ichorous discharge, and the toes thickened round the base of the nails, as if they were inclined to drop off. The common alterative medicine should be given, and a lotion composed of
hydrarg. oxym. gr. vi., alcohol
[Symbol: ounce]
j., et aq. calcis
[Symbol: ounce]
iiij.
, should he applied to the feet three times every day. Leathern gloves should be sewn on them. These cases are often very obstinate.
Generally
speaking, the dog has five toes on the fore feet, and four on the hind feet, with a mere rudiment of a fifth metatarsal bone in some feet; but, in others, the fifth bone is long and well proportioned, and advances as far as the origin of the first phalanx of the neighbouring toe.
The editor begs leave to add a more detailed and systematic treatise of the affections generally attacking the feet and limbs of our dogs:
Contents/Detailed Contents, p. 7/Index
Inflammation of the feet, a disease somewhat analogous to founder in horses, and often attended with equally bad results, particularly in the English kennels, is comparatively rare with us, although there are few sportsmen but have met with some cases among their dogs. The feet become tender, swollen, and hot, violent inflammatory action sets in, the toes become sore, the claws diseased, and the balls very painful, and often suppurate.
The animal is thus speedily rendered useless; not being able to support his body, owing to the intense pain, he remains in his house, and employs the most of his time in temporarily assuaging his sufferings by constantly licking the diseased members.
Causes
. — Running long distances over frozen or stony grounds, hunting over a rough and ill-cleaned country, over-feeding, confinement, and lazy habits, are all conducive in some measure to this affection.
This form of disease is not uncommon among those dogs used in toling ducks on the Chesapeake bay, these animals being obliged to run incessantly to and fro over the gravel shores, in their efforts to attract the canvass-back. We have seen many dogs that have been made cripples by this arduous work, and rendered prematurely old while yet in their prime. It would certainly be wise and humane on the part of those who pursue this sport either for pleasure or gain, to provide suitable boots for these sagacious animals, who in return would repay such kindness by increased ardour and length of service. These articles might be made of leather, or some other durable substance, in such a manner that they could be laced on every morning before commencing their labours.
The claws should be allowed to project through openings in the boot, as this arrangement will give much more freedom to the feet, and the boot itself will not be destroyed so soon by the penetration of the toes through its substance. Boots thus neatly made will neither interfere with his locomotive nor swimming powers, but add greatly to the comfort of the animal, and secure his services for many years.
Treatment
. — No stimulating applications to the feet are to be used, such as salt water, ley, fish brine, or urine, but rather emollient poultices and cooling washes. These last-mentioned remedies should be carefully applied, and the dog confined to his house as much as possible: in fact, there is little difficulty in restraining him in this respect, as he has but little inclination or ability to move about.
Purging balls should be administered every night, and blood abstracted if there be much fever, as indicated in the heat, swelling, and pain of the limbs.
If the balls continue to swell, and there is a collection of pus within them, they may be opened by the lancet, and the contents evacuated, after which apply a linseed poultice. When the inflammation has subsided, simple dressings of melted butter or fresh lard will generally effect a cure.

Dogs frequently have a pustular eruption between the toes, either accompanying mange or some other skin disease, or entirely independent of any other affection.
Causes
. — Want of cleanliness, bad housing, improper food, vermin, and depraved constitution.
Treatment
. — Frequent washing with castile soap and water will correct this disease; the feet and legs after washing should be rubbed dry, particularly between the toes. When the pustules are large, they may be opened with the lancet and a poultice applied. If the disease appears complicated with mange, or dependent upon other general causes, the primary affection must be removed by the proper remedies, which generally carries off with the secondary disease.

It is not an uncommon occurrence for dogs, while running, climbing fences, or jumping ditches, to sprain themselves very severely in the knee, or more frequently in the shoulder-joint; and if not properly attended to, will remain cripples for life, owing to enlargement of the tendon and deposition of matter.
We once had a fine, large, powerful bull-dog, that sprained himself in the shoulder while running very violently in the street after another dog, and in some way, owing to the great eagerness to overtake the other, tripped up when at the top of his speed, fell on his chest, and when he arose commenced limping, and evidently suffered from considerable pain. On taking him home, we examined his feet, limbs, and chest very particularly, expecting to find a luxation or fracture of some of the bones of the leg or feet, or perhaps the presence of a piece of glass or other article deeply imbedded in the ball. None of the above accidents, however, being brought to light by our examination, or that of a medical friend who expressed a wish to see our patient, we concluded that a simple sprain of some of the tendons had taken place.
On the following day there was slight swelling and tenderness of the shoulder-joint, accompanied by great unwillingness to put the foot to the ground, owing to the pain that seemed to be produced by the extension of the leg. The limb was fomented, and the dog confined for several days, till the swelling and tenderness disappeared; but, greatly to our astonishment and that of others, he still remained lame as before.
This lameness continued for several months, when we parted with him, sending him to a relative in the country, who informed us that he never recovered the use of his limb, but that it became shrivelled and deformed for want of use.
The cause of lameness in this dog is as unaccountable as some cases of lameness we see in horses. We are convinced that there was neither fracture nor luxation, nor any other unnatural displacement of the parts, and can attribute it to nothing but enlargement of one of the tendons of the shoulder-joint resulting from inflammation. If it had been in our power, we should have liked to have examined this animal after death.
Treatment
. — Hot fomentations to the part affected, together with purging balls and bleeding, if there be great tenderness and swelling of the limb. When the inflammation and tumefaction have disappeared, rub the parts with opodeldoc, or other stimulating mixtures.

Dogs are apt to cut their feet by stepping upon sharp tools, bits of oyster-shell, old iron, &c., or by the introduction of thorns, burrs, nails, bits of glass, and other articles, into their balls.
Treatment
. — If the cut be very deep, or divides the ball, the foot must be washed in tepid water, and the edges of the wound drawn together and retained in their position by a couple of sutures or a strap or two of adhesive plaster, and the animal confined.
Where thorns or sand-burrs have pierced the foot, diligent search should be made to extract them, or the wound will suppurate, and the dog continue lame for a long time. This caution is particularly necessary when minute particles of glass have entered the foot. A poultice in such cases should be applied, after removing every particle within our reach, and the, foot be wrapped up, or, what is better, enclosed in a boot of some kind, sufficiently strong to protect it from the dirt or other small particles which otherwise would enter the wound and prevent its healing. In a case of great emergency, one of our friends hunted a setter dog three successive days in a leather boot, which we instructed a country cobbler to put on him to protect his foot from a recent and deep cut, that he had received from treading upon some farming utensils. The boot was taken off every night, the foot nicely cleaned, the leather oiled and replaced ready for the following day. The wound afterwards healed up, and no trace of the incision now remains. The boot should be made of stout, flexible leather, and extend beyond the first joint; the seam must be in front, so as not to interfere with the dog's tread. There should be openings for the claws, and the sole large enough to allow the expansion of the ball pads when in motion: a small layer of tow had better be laid on the bottom of the foot before putting on the boot.
It is often very difficult to tell the exact spot where a briar or thorn has entered the foot, owing to its penetrating so far into the substance of the ball as to be entirely concealed under the skin, or by the swelling of the parts surrounding it. In all such cases the bottom of the foot should he gently pressed by the thumb, and the point where the dog exhibits symptoms of must pain should be, particularly examined, and, if necessary, cut down upon to extract the extraneous substance, no matter what it may be.

The nails of some dogs require occasional cutting, otherwise they grow so long and fast that they turn in and penetrate the ball of the foot. If we cut them, a strong, sharp knife is necessary for the purpose; filing them off we consider far preferable.

Dogs, as well as horses, become lame from stiff joints, splints, and sprains. Stiff joints are occasioned by anchylosis, or the deposit of calcareous or osseous matter within the ligament or around the head of the bone, which latter defect is known as ring-bone in the horse.
Treatment
. — Stimulating friction to the parts, such as spirits of camphor, or camphorated liniment, mercurial ointment, tincture of iodine, opodeldoc, blistering, &c. —

These are of not unfrequent occurrence in the dog; and I once had five cases in my hospital at the same time.
In the human subject, fractures are more frequent in adults, and, perhaps, in old men, than in infants; but this is not the case with the smaller animals generally, and particularly with dogs. Five-sixths of the fractures occur between the time of weaning and the animal being six months old; not, perhaps, because of their chemical composition, that the bones are more fragile at this age; but because young dogs are more exposed to fall from the hands of the persons who carry them, and from the places to which they climb; and the extremities of the bones, then being in the state of
epiphysis
, are easily separated from the body of the bone. When the fracture takes place in the body of the bone, it is transverse or somewhat oblique, but there is scarcely any displacement.
A simple bandage will be sufficient for the reduction of these fractures, which may be removed in ten or twelve days, when the preparatory
callus
has acquired some consistence. One only out of twenty dogs that were brought to me with fractures of the extremities, in the year 1834, died. Two dogs had their jaws fractured by kicks from horses, and lost several of their teeth. In one of them the anterior part of the jaw was fractured perpendicularly; in the other, both branches were fractured. Plenty of good soup was injected into their mouths. Ten or twelve days afterwards, they were suffered to lap it; and in a little while they were dismissed cured.
It will be desirable, perhaps, to describe our usual method of reducing the greater part of the fractures which come under our notice.
