Why does my dog vomit?

Vomiting is quite common in dogs. They do not necessarily underlie serious disorders, but they must force us to pay close attention to what they eat and their way of life.

In some cases, in fact, vomiting becomes much too frequent and painful, suggesting a serious enough illness requiring urgent medical care. Why does the dog vomit and what to do when it is?

Possible causes of vomiting in dogs ?

Before any choice, it is essential to distinguish between vomiting and regurgitation.

These are 2 things that should not be confused. Vomiting is a reflex action that actively removes the contents of the stomach through the mouth.

Regurgitation, on the other hand, is a rejection without active contraction of the abdomen of saliva or undigested food.

In any case, however, you will have to put your dog on the diet for several hours. Just give him water because vomiting causes, as in humans, significant dehydration.

If symptoms of vomiting persist, consult your veterinarian to determine the cause.


The causes of vomiting are multiple:

  • Food intolerance (lactose, cow’s milk protein, for example)
  • From a food allergy
  • Inflammation of the stomach
  • An ulcer
  • From poisoning by chemicals or household
  • Ingestion of a damaged
  • Ingestion of a foreign body

Diabetes mellitus, renal or hepatic insufficiency, peritonitis (inflammation of the abdominal walls) and pancreatitis are also likely to manifest themselves through vomiting.

Only the veterinarian is able to establish an accurate diagnosis to shed light on what is causing the vomiting, and therefore to implement the appropriate treatment protocol.
