Describe the treatment of a case of eczema in the dog, explaining fully. 

 In the erythematous, papular, and vesicular stages zinc oxide 

 ointment or zinc oxide and starch dusting powder may he used. 

 In the weeping stage 6 per cent, solution of nitrate of silver or some 

 desiccant powder such as horic acid, lycopodium, or bismuth sub- 

 gallate is used to check the weeping. Chronic eczema is treated with 

 oil of cade, sulphuretted potash, Peruvian balsam, or creolin in suit- 

 able dilutions. Internally, Fowler's solution of arsenic is of great 

 benefit. 



In all forms dietetic measures are employed ; a laxative diet and 

 occasional doses of sodium sulphate help materially. Cleanliness 

 is important, and in this connection bathing with a non-irritating 

 soap and water is paramount.

Discuss venesection. What therapeutic measures may be used in place 

 of venesection? 

 Venesection, or blood-letting, is employed chiefly to rapidly 

 relieve conditions associated with a high arterial pressure and local 

 engorgement of some organ. It reduces temperature and relieves 

 congestion, dyspnoea, and cyanotic conditions. "Venesection is 

 employed in plethoric animals only, in acute pleurisy, pulmonary 

 congestion, acute laminitis, urticaria, acute cerebritis or meningitis, 

 parturient apoplexy in cows, etc. It is also employed in toxaemias 

 to remove the blood and its contained poison. Four to six and often 

 eight quarts are drawn from the horse. 



Circulatory depressants as veratrum viride or aconite cause a 

 general reduction of arterial tension and relieve local congestion. 

 Cathartics, diuretics, and diaphoretics abstract fluid from the blood- 

 vessels and thus lower blood-pressure. Notable among these are: 

 arecoline, potassium nitrate, and pilocarpine.
