202 THE HORSE IN HEALTH AND DISEASE 



To correct this defect, shoes are apphed to increase and quicken 

 the action in the fore limb and retard it behind. The front shoe 

 is made with short heel calks which slant forward, and no toe calk. 

 The hind shoe has two lateral toe calks or clips and is set back a 

 little from the toe wall. 



Interfering is a striking of the supporting leg by the opposite 

 foot. The hair is rubbed off and in some cases a severe wound is 

 produced. The causes of interfering are fatigue from unaccus- 

 tomed or overwork; bad conformation, more especially the base- 

 wide and toe-narrow standing position ; faulty or neglected shoeing. 

 Each case must be studied and treated on its merits. A shoe with 

 a thick, heavy outer heel calk helps to correct the improper gait.
