Inflammation of the Investing 3fembrane of the Lungs, and that which lines the Chest-Cavity - etc.) - On this subject I give Dalziel's treatment complete.

These two diseases are sometimes co-existent, when it is known as pleuro-pneumonia. It would be too much to expect an amateur to distinguish between them; but as the causes and treatment are much the same, I shall continue to treat them as one disease. This disease is of very common occurrence in dogs, and in many cases proves fatal. When it exists as a complication of distemper it is known as "chest distemper;" but other pf the respiratory organs may be involved.

The causes producing inflammation of the lungs are generally exposure to severe cold, allowing dogs to swim during inclement weather, clipping dogs or otherwise removing a greater part of their natural covering, or washing them and afterwards exposing them to excessive cold, especially If not thoroughly dried. In fact, any sudden transition from a high to a low temperature may produce it, especially in dogs of a delicate constitution and unused to roughing it. Again, it may occur from over-exertion through running too far, or from fractured ribs penetrating the lung-tissue.

The more notable symptoms are quick and labored breathing, the in* spirations being full, the expirations short, and the breath hot. The dog sits on his haunches, and if obliged to move does so reluctantly, and soon resumes that position, with his head pushed forward. The ribs are mora or less fixed, and the abdominal muscles brought into action, especially if pleurisy is present. The fixed position of the ribs, with the heaving of the flanks, is a most characteristic symptom of pleurisy. In affections of the lungs, the animal stands with its legs (fore legs) wide apart. If the disease progresses, the face has a haggard expression, the angle of the mouth is drawn up, and the extremities become deathly cold. If not relieved, the dog rapidly gets worse, and the breathing becomes more labored and painful.

Pleurisy, or inflammation of the investing membrane of the lungs, often exists independently, or as a complication of pneumonia. To treat this disease with any chance of success it is important that the dog should be kept where he can freely breathe fresh, cool, air; & hot. stifling; place is equally to be avoided with a damp or draughty one. Whilst cool, fresh air is insured, the patient must at the same time be kept warm by clothing: if neeessary; it is also needful that he should be as little distrubed as possible. If the legs are cold, woollen bandages should be placed on all of them. The diet should be rather low at first, but not too much so - broth, gruel, etc., are suitable under the circumstances.

In the way of medicines, it is necessary that the bowels should be kept open by castor oil or the use of clysters. The Fever Mixture - which find given under Catarrh, should be immediately and diligently administered.

Blisters to the sides, as sometimes advised, are bad, as they cause soreness and increase the pain in breathing. Hot-linseed poultices should alone be employed throughout the day and night. If the fever is high, give 1/2 to 1 drop of tincture of aconite every fifteen minutes for two hours, then hourly for eight hours.

Dogs recovering from this disease are always very weak, and require very great care to prevent a relapse, even when all danger appears to be gone. Only the most gentle exercise should be allowed at first, and fine weather selected for it. The dog will require nourishing diet, which should be plain, and consist for a time of broths, etc. a return to solid food being gradual. The dog will at this stage be greatly benefited by tonics and to build him up use either Eberhart's Tonic Pills, or Sergeant's Condition Pills.
