This comes from a number of causes; irritants accidentally swallowed, sometimes by mineral or other poisons carelessly thrown out by those who have used them for poisoning rats. The use of areca nut of turpentine will cause inflammation. The dog may have accidentally swallowed something of an irritating nature while helping himself from the garbage barrel, as many dogs will do.

The Symptoms are excessive thirst and violent vomiting, and between these the dog will lie on his side, stretched out, whining and moaning from the pain he is suffering. When this is observed administer from 1/4 grain to 1/2 grain of hydrochlorate of cocaine.

Treatment

Keep the dog undisturbed, with a constant supply of water that has been boiled, within reach, and give him mutton broth made with barley and a little isinglass added to it. To allay the pain a very little opium may be given. Less medicine in such a case is the better plan to follow. If diarrhea should follow, which is very likely, this must be treated as directed under that head.
