296 The Diseases of Animals 



horse is made to jump quickly by a cut from a whip, or 

 after walking a short distance. 



These forms of chorea are most severe in cold weather 

 and usually gradually increase in severity as the ani- 

 mal grows older. In dogs, chorea is usually seen as an 

 irregular jerking of the muscles of the head or some 

 other part, or even the entire body. In horses, there 

 is sometimes a jerking of sets of muscles, unless the 

 disease is severe. Chorea does not seem to cause suffer- 

 ing, nor to interfere seriously with the general health 

 of the animal. 



In most cases of chorea, medicinal treatment does 

 not give great benefit, unless it is the result of other 

 disease. Good results often follow careful feeding and 

 tonics. The food should be nutritious, easily digested, 

 of good variety, and abundant. For horses, a mix- 

 ture of oats, oil-meal and bran is good. Give the 

 horse three times a week the following: Common salt, 

 four ounces; sulfur, two ounces; hard- wood ashes, 

 two ounces; — a tablespoonful of the mixture in the feed. 

 Also, give Fowler's solution (of arsenic), beginning 

 with half -ounce doses in the feed, once daily, and 

 gradually increasing by one-fourth ounce at a titne 

 until one ounce is given at a dose in the morning 

 and the same at night. The arsenic should be given 

 for two weeks and then withheld for two weeks and 

 repeated. Dogs maybe given Fowler's solution, begin- 

 ning with one -drop doses once daily and increased 

 one drop a day until five to ten drops (depending on 

 the size of the dog) are given three times daily. 

 Simple syrup of hypophosphites should be given in
