The vomiting of your dog does not fade? In this case, you must consult. Previously, nothing serves to panic. That your dog is vomiting is nothing unusual in animals. Except when it becomes recurrent.


The vomiting are quite common in dogs. They do not necessarily underlie serious disorders, but they must push us to pay close attention to what they eat and their lifestyle. In some cases, in fact, the 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
Above all, it is essential to distinguish between vomiting and regurgitation . These are two different things that should not be confused. Vomiting is a reflex action that actively removes the contents of the stomach through the mouth. The regurgitation is, meanwhile, a rejection without active contraction of the abdomen saliva or food undigested .

In any case, however, you will have to put your dog on the diet for several hours. Just put it in 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 food
  • Ingestion of a foreign body (toy of small size, string ...)
  • My dog ​​is vomiting: is he sick?

Vomiting is a symptom of many diseases that are not necessarily digestive. These include parvovirus (caused by canine parvovirus type 2), distemper (contagious viral disease), Rubarth hepatitis (caused by canine adenovirus type 1), leptospirosis (caused by bacteria of the genus Leptospira) or, in females, the pyometra , which is an infection of the uterus.

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.

Internal parasites
A dog infected with an internal parasite can also start to vomit. By developing in the digestive tract of the animal, parasites irritate it and cause inflammation . This is why it is important to deworm your dog regularly and appropriately. Elimination of internal parasites is a priority, as is vaccination .

An object
Your dog may have swallowed an object . This foreign body causes a de facto blockage in the digestive tract of your dog. This can lead to vomiting. This is an emergency.

Gastritis
It can be fatal if not treated in time. Gastritis is manifested by inflammation of the inner lining of the stomach . Gastritis can be acute or chronic .

The vomit of your dog can be accompanied by blood, following a rupture of a vessel. Your dog can be emptied by the top as well as the bottom. It is urgent to consult your veterinarian who will prescribe medication.

Bilious vomiting
Your dog may be producing too much bile in his digestive system. He has bilious syndrome . This causes vomiting when the stomach is empty. They vomit bile. This phenomenon joins the gastritis described above. Indeed, bile ignites the stomach that is irritated.

The solutions are of course medicated with treatments that will reduce the acidity of your dog's stomach. They are also in the way of giving rations to your pet. Space them less, so that the stomach does not empty completely.

How to relieve and when to consult a veterinarian for a dog who vomits?
In case of vomiting, it is recommended to give nothing to feed his dog for half a day (12 hours), but without depriving him of water. He must be able to drink whenever he feels like it. If vomiting persists, it is necessary to take him to the vet.

You really need to worry and consult a veterinarian if your dog:

  • produces repeated or severe vomiting
  • has an advanced age or a puppy
  • vomits abnormally with an unusual appearance (black color or blood spots)
  • experiences other symptoms such as lack of appetite , fever , diarrhea , dehydration or swollen belly .

In any case, it is important to see the content of the rejection and give a precise description to the veterinarian (take a picture ideally), because its appearance can give valuable information on the possible underlying disease. If the dog tries to vomit but can not, it can be a potential sign of dilation or torsion of the stomach . This is an emergency and the animal must be hospitalized without delay.
