_Symptoms_: Convulsions; coma; heavy stertorous breathing, with pupils contracted. A great assistance in the diagnosing of these cases is the smell of the turpentine in the breath; the bladder is very irritable; the urine has the odour of violets, and is passed frequently. _Treatment_: Give an emetic as soon as possible. The best in these cases, as in many others, is the apomorphia, from two[1] to five drops of the one in fifty solution, injected under the skin, or double the quantity poured down the throat. Failing this, give from five[1] to twenty grains of sulphate of zinc, in water, or some powdered ipecacuanha. When the effect of the emetic has passed, a full dose of sulphate of soda, from one[1] drachm to one ounce, in water, should be given. The dog may be allowed to drink milk or white of egg, with water or rice water. When there is much pain about the abdomen, a morphia suppository inserted into the bowel gives relief. _Oxide of Zinc_, either in the form of lotion, ointment, or the powder, is a household remedy, and an exceedingly good one, too, for many forms of non-contagious skin disease; but like almost everything else, when applied to the dog’s skin, he makes it his business to remove it with the tongue as quickly as possible. A small quantity does no harm; but when the ointment or lotion is applied over a large surface, and the dog licks a large quantity off, serious disturbances of the system often follow. Acute cases of this kind are not so fatal, as a rule, as chronic ones—that is, as in those cases of long-standing skin trouble when the zinc has been in daily use for some time, and the animal has been systematically licking it. In these cases the ill effects of the zinc are first noticed by the dog vomiting after food. _Symptoms_: There is great thirst and loss of condition; soon the dog refuses food altogether, the sickness increases, and becomes very frequent. If the mouth is examined, the inside of the lips and tongue will be noticed extremely pale—in fact, quite blanched—and the membrane of the eyes is in a similar condition. The dog is very cold and dejected. Diarrhœa often comes on, which adds to the weakness. _Treatment_: In treating these cases, the application of the oxide zinc in any form, of course, should be immediately discontinued. A purge should be given; for this, from two[1] to fifteen grains of jalapin is as good as anything. This should be repeated in two or three days. Medicine to strengthen the system and stop the sickness should be given, as the following mixture:— _Recipe_: _The Mixture_: Dialysed Iron, 2 to 8 minims.[1] Solution of Arsenic (Fowler’s), ½ to 2 minims. Bicarbonate of Soda, 3 to 10 grains. Compound Tincture of Gentian, 5 to 20 minims. Water, from one[1] to four teaspoonfuls. Repeat three or four times a day.
