As it is a dog's license to vomit easily and almost at will, an attack may-mean much, and it may be of the least importance. Often a hearty meal will he bolted to be immediately expelled, and again more leisurely eaten, a mere case of overloading the stomach.

Vomiting is frequently associated with pulmonary disorders, caused by thick mucus lodging in the throat. It is a very common symptom in dis-eases of the stomach and intestines, oftener the former.

Matter vomited may be undigested food or mucus alone, the latter a more urgent symptom. Blood may be vomited if there is much straining, and is unimportant if the quantity is small. When it is fresh, bright red in color, and ejected in quantity, the cause may be a sharp bone lodged in the passage to the stomach, and the lining membrane lacerated.

Gastric ulcer may be suspected when a severe hemorrhage occurs, and it is more probable if a previous attack has been experienced. If a dog vomits often within a short time, bile will frequently appear mingled with the matter raised; its presence then is purely mechanical, the continued retching drawing it up into the stomach, instead of permitting it to flow down the intestines. Vomiting is symptomatic of a variety of affections exclusive of inflammation or structural diseases of the stomach.

Treatment

The cause should be studied and if possible removed. If occasioned by indigestion, worms etc., appropriate remedies are directed in the treatment of those diseases.
