DISEASES AND TREATMENT OF THE HORSE 269 
months because of the probability of being allowed to stand 
for longer periods in the stable. It is met with, however, at 
any time of the year. 
Symptoms. — When taking a horse out of the stable, he 
may go off full of life for a quarter of a mile to a mile, or 
even a longer distance in some cases. He then breaks out in 
a sweat, becomes stiff in the hind quarters and unable to trot. 
He breathes heavily, his pulse is quick and weak, and he 
trembles about the flanks. The muscles of the back and hips 
are swollen and as hard as a board. Attempt to drive him 
still further and he becomes so stiff that he is not able to go, 
falls down and is unable to rise. At this stage all the symp- 
toms mentioned above are increased greatly. His urine is of 
a dark red color and scanty, due to the kidneys not acting 
properly. Obtain a portion of the urine and allow it to stand ; 
the acids come to the top. In severe cases the legs and ears 
are very cold.

Treatment. — As soon as the symptoms are noticed, stop 
driving him and take him to the nearest stable, for if the 
driving is continued he only falls down and is a great deal 
more trouble. When in the stable, cover him well with 
blankets and allow him to sweat profusely. This relieves the 
kidneys. Give him a good rubbing all over the back and hips
