Causes. — Sprains, bruises, hard and_ fast work, and penetrating 

 wounds invohdng the periosteum; improper shoeing, such as 

 cutting the toe too short or lea\dng the heels too high, or leaving 

 one side of the hoof wall higher than the other. 



Symptoms. — Lameness, which may disappear with exercise, is 

 usually the first symptom observed. Later, there appears a hard, 

 painless swelling, over which the skin is freely moveable. 



Treatment .—Remoxe the shoe and level the foot. Use cold baths 

 and cold packs for a week, 

 then apply a hiniodide of mer- 

 cury blister. Keep the animal 

 in a level stall and gi^e per- 

 fect rest for four to six weeks. 



389. Side bone (fig. 42) — 

 Side bone is a condition in 

 which the cartilages of the 

 foot have changed to bone. 

 The disease is most frequently 

 Been in heavy draft horses and 

 in draft and pack mules. The 

 front feet are affected more 

 often than the hind ones, and 

 the outer cartilage suffers more 

 frequently than the inner one. 



Causes. — Concussion pro- 

 duced by fast work on hard 

 roads; allowing the feet to be- 

 come dry and hard; lack of 

 frog pressure; mechanical in- 

 juries, such as treads and 

 similar wounds ; and improper 

 shoeing, i. e., leaving the heel 

 too hign or the use of high 

 heel calks. 



Symjotoms. — A hard, unyielding condition of the cartilages of the 

 foot, with or without lameness. 



'Treatment. — This is necessary only when the animal is lame. In 

 such cases remove the shoe, level the foot, and stand the horse in 

 cold water for several hours a day, or apply a swab around the coronet 

 and keep it wet with cold water. As soon as -the inflammation haa 

 disappeared, apply a blister of hiniodide of mercury over the part 

 and keep the animal quiet in a level stall for three weeks.
