the horn carefully from about the wound, remove the offending object 

 if present, and establish drainage. Clean the wound thoroughly 

 with a strong antiseptic solution; dry it well with clean cotton and 

 apply tincture of iodine. The foot is then well bandaged and the 

 animal placed in a clean, dry stall. Repeat the dressings twice 

 daily until pus formation and lameness cease. The wound is then 

 packed with tar and oakum and the horse shod as directed in par- 

 agraph 453. 



460. Quittor. A chronic inflammation of the cartilages of the 

 foot and their surrounding structures, characterized by the presence 

 of one or more small openings (fistulas) from which there is a continu- 

 ous discharge of pus. 



Causes. Treads on the coronet, suppurating corns, and bruised 

 and punctured wounds of the sole. 



Symptoms. Heat, swelling, and tenderness in the region of the 

 coronet and heel, usually the inner one. The inflammation may 

 subside, but usually an abscess forms and discharges a bloody pus, 

 after which the swelling may disappear, leaving one or more small 

 canala (fistulas, sinuses) 1 or 2 inches in depth. There is usually 

 lameness. 



Treatment. Rest. If due to a nail wound, a tread or a suppurating 

 corn, treat accordingly. The canals may be injected twice daily 

 with tincture of iodine and a pack of a 1 to 1,000 solution of bichloride of 

 mercury applied. If this does not affect a cure, an operation will be 

 necessary. 



461. Seedy toe. A mealy condition of the horn of the wall, 

 usually in the region of the toe. 



Causes. Usually results from an attack of laminitis. Excessive 

 moisture is also said to be a cause. 



Symptoms. A crumbling and breaking away of the white line 

 between the wall and the sole, leading to the formation of a hollow 

 wall. By tapping on the wall of the diseased part a hollow sound 

 may be heard. 



Treatment. Scrape out the soft, crumbly horn and clean the 

 cavity well; apply tincture of iodine or pure creolin and pack with tar 

 and oakum. The foot is then shod with a leather pad and a bar shoe. 

 A cantharides blister should be applied to the coronet to stimulate 

 the growth of the horn. 



462. Thrush. A disease of the frog characterized by an offensive 

 odor and a softening of the horn.
