4. Corns. 



Corns may affect any foot or either heel. They are, 

 however, more generally found on the front feet and more 

 frequently affect the inside heel. 



Symptoms. — The horse is more or less lame in most 

 cases, and is more so just after he bruises it. When stand- 

 ing, if it is in one foot, he points that foot out; if in both feet, 

 he first points one out and then the other, changing from one 

 to the other frequently. He goes pretty well 

 on soft ground, but gets lame as soon as he 

 strikes a hard piece of road. On raising the 

 foot and tapping or pressing on the affected 

 quarter, he flinches. In taking the shoe off 

 and paring down the quarter, a red spot in 

 the corner of the sole is exposed. In case the % 

 corn becomes bruised and festers, the symp- M 

 toms will be more severe. He holds up the V4\ 

 foot and in walking he steps long, and on the 

 toe, then hops on the other foot. The affected 

 quarter is hot and tender when pressed upon, Fig. 57.— Position 

 and if he does not soon get relief it festers of a Corn ' 

 and breaks out at the top of the hoof. 



Treatment. — In many cases it is not necessary to lay him 

 off, but shoe him so that the shoe will not press on the heels 

 and apply a poultice of hot linseed and bran to the foot for a 

 few nights. A bar shoe is a very good one to put on, as it 

 throws the weight on the frog and relieves the heels and 

 quarter. If a festering corn, remove the shoe and pare down 

 into the corn until you strike the matter. Allow it to escape ; 

 this will give him relief. Then poultice as above mentioned 

 and allow the animal to rest a few days, and when you are 

 going to use him again shoe him with a bar shoe. See that 

 the shoes do not press on the heels and quarters, and if the 

 soreness continues, blister around the affected quarter with 

 the same blister that is used for chronic founder. For after 

 treatment keep the animal shod regularly and see that the 

 shoes do not press too much on the heels. 



5. Thrush. 



This is a disease that affects the frog. It is mostly met 

 with in the hind, but often affects the front feet.
