As a rule, dogs poisoned by arsenic die, only the mildest forms making recovery.
Under any circumstances it is advisable to seek the assistance of a M.R.C.V.S., acting in accordance with his instructions.
In the absence of professional aid, provided the animal is not too much exhausted, an emetic should be given, and for this purpose there is nothing more suitable than 20 grains of white vitriol (sulphate of zinc), or the same quantity of blue vitriol (sulphate of copper), mixed with a couple of tablespoonfuls of tepid water. If neither of these agents are handy, use mustard, salt, and water.
Teaspoonful doses of brandy, mixed with the same quantity of olive or salad oil, can be given at frequent intervals.
Twenty-drop doses of chlorodyne, may be added if the pain is severe.
Hot fomentations to the belly will do good.
ANTIMONY
The compound of this element most commonly in use for medicinal purposes is that known as tartar emetic—an exceedingly active poison. Minute doses are sometimes prescribed in order to induce vomiting, and in bronchial complaints to produce expectoration.
The symptoms and treatment are practically on a par with those laid down for arsenic. Vomiting and extreme depression of the vital powers are specially significant symptoms.
Both arsenic and antimony have their special antidotes, though even these are of very doubtful efficacy.
