KNUCKLING. 



Causes. — From hard and fast work. Horses that stand 

 •iraight on the fetlock are more apt to knuckle. 



SymptOItlS. — There will be a jerking forward of the fetlock 

 every time the animal steps, and in standing the animal stands 

 with his fetlock joint bent forward instead of back. 



Treatment. — If it is a case of long standing there can be 

 nothing done, but if it is only coming on blister him around 

 the fetlock and turn him out. Blister with 



Powdered Cantharides or Spanish Fly 2 drams. 



Vaseline or Lard 1 ounce. 



Mix and apply around the fetlock, rub the blister in well and 



allow it to stand for three days, then grease and let it go for a few 



weeks and blister again ; repeat the blistering until the joint gets 



strong. There will be enough in the above prescription to blister 



two fetlocks. 



KNUCKLING IN COLTS. 



Causes. — From being left in the stable without getting mush 

 exercise during the winter and in the spring he will be knuckled 

 in the fetlocks. 



Treatment. — Before turning him out blister around the fet- 

 locks well with the above blister, and in three days afterwards 

 grease and turn him out to pasture. 



INTERFERING, OR STRIKING THE FETLOCKS. 



This trouble is mostly met with in colts when they are 

 first shod. 



Causes. — Sometimes from shoeing with too heavy a shoe and 

 putting the horse on a long trip before he is used to it. Some 

 horses naturally travel so close behind that they brush the legs 

 together. 



Symptoms. — Soreness on tne inside or" c le t'etiock, and some- 

 times the hair and skin will be knocked off, ind in severe cases 

 will swell badly When the horse, in travelling, strikes himself he 

 will hop on three legs with pain for a little piece, then be all right 

 until he strikes again. 



Treatment. — Bathe the leg well with lukewarm water and a little 

 castile soap twice a day, if it is swoolen, after bathing rub dry and 

 apply the white lotion. Have the shoes changed and tm^de light. 

 If the animal is in poor condition, feed him well and do not work 

 him too hard until he gets strong and in good shape for his work.
