Hiccough arises from indigestion, and often annoys house pets that are given improper food, such as sweets, etc. A wineglassful of lime water in a tumbler of milk to drink, and for a 20 lb. dog 10 grains of bicarbonate of soda, and 10 drops of sal volatile in a tablespoonful of milk, will usually prove effectual. Another remedy I have used is camplior water (not spirits). Give a 20 to 40 lb. dog a teaspoonful and repeat in five minutes.
