WOUNDS 235 



Where an actual wound is to be seen, and where advice 

 is sought early, then a more favourable opinion ma,y be 

 advanced. In this case antiseptic measures, commenced 

 early and persisted in, may prevent the rise of further 

 mischief. 



It goes without saying that, should there arise any other 

 of the complications we have mentioned (viz., Arthritis, 

 Necrosis of the Extensor Pedis, Sand-crack, Quittor, and 

 False Quarter), the fact should be pointed out to the owner, 

 and the prognosis regulated thereby. 



Treatment — Preventive. — Seeing that at any rate the 

 majority of cases of coronitis result from injuries inflicted 

 by the shoes, we may look at once to that particular for a 

 means of prevention. 



Take first the case of ' treads.' There is no doubt that 

 they are most common in animals shod with heavy shoes 

 and with high and sharp calkins. This suggests at once 

 that a preventive is to be found in substituting a calkin 

 that is low and square. 



Where the injury is an overreach, and where, on account 

 of the animal's pace and manner of gait it is in risk of being 

 constantly inflicted, the shoeing should be seen to at once. 



We have already pointed out that it is the inner border 

 of the lower surface of the toe of the hind-shoe which, in 

 the act of being drawn backwards, inflicts the injury. (See 

 Fig. 110). 



In this case prevention may be brought about either by 

 shoeing with a shoe whose ground surface is wholly con- 

 cave, or by bevelling off the sharp border (see Fig. 110, a, 

 p. 236). When the tendency to overreach is not exces- 

 sive, prevention may in many cases be effected by simply 

 placing the shoe of the hind- foot a trifle further back- 

 wards than would ordinarily be correct, thus allowing the 

 horn of the toe to project beyond the shoe. This at the 

 same time does away with the annoyance of ' forging ' 

 or ' clacking,' which, as a rule, accompanies this condition. 



While recognising the value of shoeing in these cases, we 

 must not forget that a great deal may be brought about by
