CRIB SUCKERS. This bad habit usually be- 

 gins in colt days. It may arise from a sore tooth.

 quently brings on colic. The best treatment is to 

 break up the habit. Examine the mouth first to see 



if anything is wrong with 

 the teeth. Muzzle while 

 standing in the stable. 

 The old cribbers never 

 give up the habit.

 Colic.

 the hind legs slipping
