326. Mode of giving a drench. 



A proper drenching bottle or horn should be provided. In its absence 

 a soda-water bottle will answer pretty well. The horse's head must be 

 slightly elevated, and then the fluid should be poured down the throat 

 very slowly. The head may, if necessary, be raised by means of a noose 

 in the mouth, attached at its upper end to the prong of a stable fork. 

 At the slightest sign of coughing the head must be released. Many 

 drenches, it must be remembered, are of such a nature as to cause great 

 irritation, if even a very small portion goes the wrong way. 



A practice existed some years ago, and may perhaps continue even in 

 the present day among farriers, of giving drenches through the nose. 

 It is both injurious and dangerous, and should be strictly prohibited.
