Your pet empties the ingested content from his stomach, which he cannot digest and which harms him. If vomiting is unusually frequent and severe, and is accompanied by other symptoms, caution is advised. 

If your quadruped vomits, a reflex reacts and the stomach is stimulated to empty its contents. This is a protective mechanism of the organism against incompatible substances and foreign bodies. 

To produce the emetic stimulus itself, the dog eats excessively on an empty stomach Grass. This is found in the sputum along with mucus and sometimes other things such as fur hair. 

What is the course of vomiting?

1. malaise and nausea

If your four-legged friend vomits occasionally, it is usually a normal behavior

He tries to get rid of the cause of his indisposition. If, on the other hand, the reaction occurs more frequently, various causes may be behind it and should be recognized at an early stage.

How does vomiting occur?

The vomiting center in the brain is responsible for vomiting. It is triggered due to different stimuli. 

These include disorders of the internal organs such as in the gastrointestinal tract, liver and kidney. The reactions nausea and vomiting report that something is wrong in the organism.

What exactly does a dog vomit?


If your pet vomits, you should take a close look at the sputum. There are clear signs that point to the cause and provide information about a possible disease.

If the symptoms appear once or twice, in most cases it is a harmless disorder. Information about the health condition of the four-legged friend is indicated by the dog itself. If he seems alert, cheerful, responsive and eats normally, he is doing well.

1. white foam or slime

If your pet vomits before eating and mostly in the morning, this can be an indication of an overacidification of the stomach. Normally, the gastric juice serves to break down proteins and activate enzymes. If the stomach has remained without content for a long time, the gastric acid attacks the stomach lining.

If this type of vomiting occurs frequently, a disease of the stomach may be the actual trigger. 

2. yellow foam or mucus

The yellow color indicates parts of bile in the gastric juice. The reason for this is a reflux of the contents from the small intestine into the stomach. 

3. much water

If your faithful friend vomits water, although he has not drunk anything before, a gastrointestinal inflammation may be responsible. 

4. the dog often vomits the food

This may be a feed intolerance, stomach irritation or even intestinal obstruction. 

5. there is blood in the sputum

It is possible that a blood vessel has been injured or a gastric ulcer has burst. If the blood shows a bright red color, it comes from the area of the mouth and throat or esophagus.

Injury from a foreign body, inflammation of the esophagus, or malignant disease are possible triggers. 

Likewise, a Poisoning or Incompatibilities be taken into consideration.

Is the blood dark redit almost certainly comes from the stomach. This is the so-called "Coffee grounds breaking". It can Inflammations, Ulcers and Tumors be responsible for this.

When does it become dangerous?

There are two situations in particular that can seriously harm your pet:

1. too little fluid in the body

During vomiting, a considerable amount of stomach contents can be expelled. At the same time, a great deal of fluid is lost. If your charge takes in too little fluid during this time, there is a risk of the Drying out or a Dehydration. Especially if he also suffers from diarrhea. 

If the kidneys are not able to compensate for the loss of water, this can be dangerous and even life-threatening for the four-legged friend. The body lacks the electrolytes potassium and chloride and the nerves and muscle cells are impaired in their function. 

Likewise, too much acidic gastric juice can be lost through vomiting. The pH values in the body get mixed up. Organ damage can be the result.

2. inhale the vomit

If the larynx does not function properly during vomiting, food or fluid easily enters the lungs through the trachea. You recognize the evil when your furbaby suffers from shortness of breath, coughs heavily and becomes apathetic or feverish.

Proper treatment

Treatment is based on the cause and symptoms. 

If it is a harmless reaction of the body, it is often sufficient if your quadruped does not receive any food at first. About 12 - 24 hours of abstinence should be sufficient. In this way, further nausea can be prevented and the irritated gastrointestinal tract calms down. It is important that your faithful companion has access to fresh water at all times. 

If the nausea subsides, the patient can again slowly gentle feed get. In order not to put too much strain on the stomach and intestines after the irritation, fat should be largely avoided. Recommended is a Gentle diet from rice or mashed potatoes and poultry meat. 

In addition, the portions should be small so that the stomach slowly gets used to eating again. If no problems occur and the quadruped tolerates the food well, it may receive the usual feeding again. 

If you do not see any improvement after fasting, you must go to the vet. Additional signs of illness are blood in the sputum and symptoms such as pain, fever and diarrhea.

Preparation of a soft diet of chicken and rice

In the case of acute discomfort, you can prepare a diet of chicken and unsalted rice for your protégé.

High quality chicken meat is recommended here. You can boil the chicken meat with bones. However, you need to remove the bones from the meat after cooking.

  1. After cooking, cut the chicken into bite-sized cubes. Let the chicken broth cool. Then skim the fat from the surface of the broth. 
  2. Take about 600 ml of the chicken broth and bring it to a boil.
  3. Meanwhile, you can thoroughly rinse a cup (about 230gr) of rice (white short grain or long grain). 
  4. When the broth begins to boil, add the cup of rice. 
  5. Let it boil again. Then reduce the heat. Cover the pot with a lid and let the rice simmer gently for about 20 minutes. 
  6. Let the rice cool completely afterwards. 
  7. Add the cooked chicken to the rice and mix well.

The ratio of rice and chicken should be between 2:1 or 3:1. After you have fed your darling with the gentle diet for a few days, you can slowly switch to his normal food in four to five days. 

If the gentle diet does not help or your dog's symptoms worsen, contact your veterinarian immediately.

The diagnosis at the vet

The examination depends on the severity and duration of the disease. The first thing is the general condition of the patient. The veterinarian will ask you about your suspicions regarding the symptoms, the possible history and the eating and other behavior. 

He then measures the fever, checks the eyes, palpates the organs in the abdomen and checks for pain reactions. So that the nausea and the agonizing nausea subside, your pelt nose receives soothing medication. Antibiotics against bacteria may also be necessary. 

If further findings are needed to clarify the disease, the physician may perform a Fecal Examination arrange 

If the general condition of the quadruped is poor, there is blood in the feces or fever or cough are involved, a blood sample is taken for a Blood test. This examination can show the function of e.g. liver and kidney, but also reveal diseases such as diabetes mellitus.

Other examination options include the Endoscopy. The doctor uses a mirror camera to look down the esophagus and into the stomach. There he can detect possible inflammations, ulcers, tumors and foreign bodies. Since the examination is painful, it takes place under anesthesia. 

Sometimes also an examination of the abdominal cavity by means of Ultrasound. The doctor looks at the internal organs of your four-legged friend and can detect changes, inflammations and foreign bodies.

Does the doctor make a X-ray image there is a suspicion of intestinal obstruction. The image shows the arrangement of the organs, possible deposits of gas or fluid in the digestive tract and abdominal cavity.

What you can do

As always, prevention, timely detection of disease, and if needed, timely treatment is critical to health. 

  • Pay attention to what and when your protégé eats
  • Give him Toyswhich he cannot break down into parts suitable for his mouth and swallow. 
  • Rooms at home Foreign body away that your four-legged friend can eat. 
  • Bring him through consistent and loving upbringing that he must not lick, chew or eat anything outdoors. 
  • Does your protégé belong to the so-called "Vacuum cleaners", which actually find everything tasty, a comfortable muzzle can give the necessary protection from poisoning and foreign bodies. 
  • Your darling should not have incompatible food ingest. These include very fatty, spicy and fried foods, raisins, some fruits and vegetables, spoiled and moldy food, unclean drinking water, water with additives from agriculture or with bitter or fermenting substances. Also nuts, chocolate, other sweets, milk, lactose, splinter bones and fish bones. You can find more in our big list: What dogs can not eat.
  • Consider the vomit of your protégé carefully. If it has an unusual consistency or color, or if there are solid pieces in it, be careful. 
  • Go to the vet immediately if you suspect poisoning. Depending on the type of toxins, they affect his organism differently. Some have an effect immediately after ingestion, while others become noticeable much later.

Home remedies for nausea


Treatment with natural home remedies is suitable only in case of a mild disorder of the gastrointestinal tract. It should be done only if the vomiting in your dog happens spontaneously and only once or twice. The remedies can only be supportive in case of a temporary disorder and cannot cure any diseases!


As long as it rarely happens and your dog is otherwise fine, you have nothing to worry about.

As soon as you notice that something is not right, you should observe him more closely and ask your veterinarian for advice. Never administer medications or herbal remedies to your charge without adequate knowledge. The wrong treatment may worsen the symptoms or disease instead of curing it.
