25. Bog Spavin. 
This is a puffy enlargement partly on the inside and 
partly on the front of the hock joint. There is an over sup- 
ply of joint oil secreted in the joint, and this bulges out the 
capsular ligament at this part of the joint. 
Causes. — Horses with round, meaty joints are mostly 
subjected to this. Keeping young colts in the stable and 
feeding them high without much exercise, fast work or strain 
of the joint will cause it. 
Symptoms. — There is a puffy enlargement on the inside 
and front of the hock joint sometimes larger than others. 
Feeling it indicates that it is full of oil. If it comes on from 
a sprain there is lameness for a few days, but this passes off 
and leaves an enlargement. 
Treatment. — If the animal is lame, bathe with lukewarm 
water and salt twice a day; in warm weather use cold water, 
and in cold weather use warm water; after bathing nib dry 
and apply the white liniment Continue this treatment for
