BREAK DOWN. 



This is where the tendons and ligaments at the back of the 

 fetlock give way and allows the fetlock to drop down almost on to 

 the ground. This is mostly seen in running or racing horses 

 where they are put to very severe exertion. 



Treatment. — You cannot restore the fetlock back to its 

 natural state, but blister once a month with the following: 



Powdered Canthardies or Spanish Flj' 2 drams. 



Vaseline or Lard 1 ounce. 



Mix and rub about half of this in along the back of the 



fetlock, allow it to stand for three days and lei the animal run out 



to pasture. Repeat the blister until you get him pretty well over 



the lameness. If he is very lame, better keep him in the stable 



for a while, and bathe with warm water and salt twice a day after 



bathing, apply the white liniment until he is pretty well over the 



lameness, then blister and turn him out. 



SPRAIN OF THE STIFFLE JOINT. 



Symptoms. — The animal cannot bring the leg forward, and it 

 is very sore when you press around the joint. 



Treatment. — Bathe twice a day with hot water and vinegar, 

 with a little salt in it, after bathing wipe dry and apply the white 

 liniment. Keep the animal quiet to give the sprained parts rest. 



DISLOCATION OF THE PETELLA OR STIFFLE OUT. 



This is where the petella or stiffle bone slips out of the pulley- 

 like process of bone in front of the stiffle joint, and as soon as this 

 slips out it locks the joint so the animal cannot move it. 



Causes. — It generally occurs in young colts or young horses 

 that are worked hard and get down thin ; it comes on by the 

 animal slipping ofif the end of a plank, or slipping while in the act 

 of getting up. 



Symptoms. — The horse will act like an animal with its foot 

 nailed to the floor ; it cannot get it forward or back. When you 

 feel around the joint it will be drawn and hard, and you can see 

 the joint bone is out too far, and when it is left out for a long 

 time the joint becomes swollen. 



Treatment. — It is very simple to treat in most cases. Have 

 an assistant to hold the animal's head and another to pull the 

 afi'ected leg \ve\l forward while you place your hand against the 

 joint and shove it in toward the animal as hard as you can, until 

 the bone goes into its place, after which the animal can move his
