The danger of these punctures are that they may start to 

 fester. This is very painful, and also very dangerous. If it 

 starts to fester, the animal holds the foot up with pain. It is 

 swollen around the top and very hot. Cut down well into 

 the hole and allow the matter to escape. Bathe with hot 

 wates and poultice to relieve the pain and draw all the matter 

 out. When a large hole is necessary and the quick bulges 

 out, burn it with butter of antimony once a day. After the 

 animal is able to walk nicely, blister the foot around the top 

 of the hoof with the same blister used in chronic founder and 

 turn him out to pasture till the soreness is all out. 



7. Pricks in the Quick. 



Causes. — These injuries are done in shoeing by driving 

 nails too close to the quick. 



Symptoms. — At the time of driving the nail the horse 

 gives a sudden jerk, showing that, the nail strikes the quick. 



Treatment. — Remove the shoe and keep the horse quiet 

 for a day or two. If he is lame poultice the foot with hot 

 linseed. If he continues to be lame, pare around the nail hole 

 and give it the same treatment that is given for punctures of 

 other nails. In any of these cases, if necessary to work him 

 when he is getting better, plug the hole with tar and cotton 

 batting and put a leather under the shoe to keep the dirt out. 



8. Quarter Crack. 



Quarter crack receives its name on account of the part of 

 the foot it affects. It generally affects the front feet, and is 

 more often found to affect the inside quarter of the foot. 



Causes. — Certain breeds of animals are more subject to 

 this than others, especially if the feet are of a brittle nature. 

 It is often met with in road horses, more especially if they 

 have high knee action and strike the ground heavily. 



Symptoms. — At first a small crack appears in the quarter 

 of the foot just below the hair. If the animal is kept at work 

 he gets lame ; the crack gets larger and longer, and sometimes 

 bleeds. If still kept working, it sometimes festers on account 

 of the irritation being kept up. 



Treatment. — Remove the shoe, pare out the bottom of 

 the affected quarter so that the shoe will not rest upon it, 

 then shoe with a bar shoe. As well as this, pare out the 

 crack all 'the way down on each side — almost to the quick —
