limb slipping sideways while running in a pasture, or slipping in-

To guard against error in 

 diagnosing affections of the 

 shoulder, it must be borne in 

 mind that all muscular tissue 

 is apt to waste if it is deprived 

 of its usual amount of exercise, 

 as we frequently see in the 

 shoulder; the shoulder shrink- FlG - 829. As a horse will travel with 

 ing on one or both sides, while lame shoulder - 



the real seat of the disease is in the feet ; therefore it is very 

 necessary to be able to distinguish shoulder-lameness from many 

 other affections with which it is apt to be confounded. Many 

 horse doctors and those about horses are apt to attribute every 

 lameness they do not understand, and whose seat is not self-evi- 

 dent, to an affection of the shoulder. 



We have seldom any recognizable tumefaction, nor much heat, 

 unless it be recent and violent. When the horse has strained the 

 shoulder, the limb is brought forward with a peculiar dragging 

 motion, as shown in Fig. 829; whereas if the trouble is in the 

 foot, the limb will be raised and brought forward without much 

 difficulty, but put down tenderly to lighten the concussion. 

 While standing, the joints will be somewhat relaxed, the heel 



raised, with the toe resting upon 

 the ground. In moving, the head 

 will be carried low, the limb 

 brought forward with a good deal 

 of difficulty and pain, and with- 

 out ability to bring it in front 

 of the other.
