10« DISEASES 



Here is a case prescribed for by Dent: 



"I have an English setter dog about twenty months old that acts as 

 though he had something in his throat. It affects his breathing, and when 

 he first showed symptoms of it his eyes were red and ran matter. He 

 eats sometimes, but at others will not eat; is healthy and bright. I can put 

 my finger under his throat and press very lightly, and it almost shuts off 

 his wind. It seems as though there was a kind of bunch in his throat 

 that is not natural. (1) Would inflammation of the larynx cause it? 

 (2) Is there such a thing as a tumor of the larynx? I had him in swim- 

 ming about four weeks ago, and when he was in the water his breathing 

 sounded like the voice of a frog. Please diagnose and prescribe. Ans.— 

 (1) Yes. (2) Yes. Your dog has laryngitis; give the following: Glycrrhiza 

 two drams, muriate of ammonia one dram, tincture opium thirty minims, 

 water to make two ounces; dose one teaspoonful every four houri." 



Lungs, Inflammation of (Pneumonia; Pleurisy — Inflammation of the 

 Investing Membrane of the Lungs, and that which lines the Chest-CaYity — 

 &c.) — 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 distin- 

 guish 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 com- 

 mon 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 

 Of the respiratory organs may be involved. 



The causes producing inflammation of the lungs are generally exposure 

 to gevere 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 consti- 

 tution 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 doeg 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 dis- 

 ease 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, a!r; a hot. stiflin* place is 

 equally to be avoided with a damp or draughty one. Whilst cool, fresh air
