When to visit the vet?
Urgent see a veterinarian within 24 hours
RED for respiratory distress, Cough/Fever (suspected aspiration), repeated episodes with weakness/Pallor, inability to swallow, Pain in the throat/chest area, collapse, or if the dog wants to eat immediately after "Vomiting" and it comes out passively/without Gagging (regurgitation) and chokes/aspirates in the process.

Definition
Regurgitation of undigested food in dogs refers to the regurgitation of food from the stomach or esophagus before the food has been completely digested.
Can Occur with the Following Diseases:
- Stomach Inflammation in Dogs (Gastritis)
- Voice Box Paralysis in Dogs (Laryngeal Paralysis)
- Esophageal Inflammation in Dogs (Esophagitis)
- Esophageal Diverticula in Dogs (Esophageal Diverticulum)
- Persistent Right Aortic Arch in Dogs (Persistent Right Aortic Arch, PRAA)
- Foreign Object in the Stomach in Dogs (Gastric Foreign Body)
- Foreign Object in the Stomach in Dogs (Gastric Foreign Body)
- Persistent Right Aortic Arch in Dogs (Persistent Right Aortic Arch, PRAA)
- Esophageal Inflammation in Dogs (Esophagitis)
- Esophageal Diverticula in Dogs (Esophageal Diverticulum)
- Stomach Inflammation in Dogs (Gastritis)
- Voice Box Paralysis in Dogs (Laryngeal Paralysis)
Basics and possible causes
Vomiting in dogs can have many different causes, ranging from harmless to serious. The basis of vomiting is the body’s physiological reaction to an irritant in the gastrointestinal tract or esophagus. Vomiting is a complex reflex controlled by the vomiting center in the brain. When this center is activated, the stomach muscles and diaphragm muscles contract, causing the stomach contents to be regurgitated.
The causes of regurgitation of undigested food can be varied. One of the most common causes is eating too quickly, where the dog swallows large amounts of food at once. This can cause the stomach to become overloaded and the food cannot be processed quickly enough. Stress or a sudden change in feeding routine can also trigger Vomiting.
More serious causes include diseases of the esophagus such as megaesophagus, in which the esophagus is dilated and food is not properly transported to the stomach. Other possible causes include gastrointestinal infections, foreign bodies in the stomach or intestines, pancreatitis (inflammation of the pancreas), food intolerances or allergies, and poisoning.
Typical accompanying symptoms
-
Loss of appetite: Vomiting is often accompanied by a reduced food intake, which may be an indication that the dog feels unwell or is in pain.
-
Weight loss: If the Vomiting is chronic or occurs frequently, the dog may experience Weight loss because it cannot absorb enough nutrients.
-
Diarrhea: Accompanying Diarrhea may indicate a gastrointestinal disease and increase the animal’s dehydration.
-
Lethargy: Dogs that vomit often appear tired and listless because the body uses energy to cope with the problem.
-
Dehydration: Vomiting leads to a loss of fluid and electrolytes, which can lead to dangerous Dehydration if left untreated.
-
Abdominal pain: The dog may show signs of pain in the abdominal area by crouching, whimpering, or not wanting to be touched.
-
Flatulence or excessive belching: These symptoms may indicate a disorder in the digestive system.
When to see a vet?
A veterinarian should be consulted if the Vomiting is frequent or chronic, as it may indicate a serious condition that needs to be treated. A veterinary examination is also advisable if other symptoms such as lethargy, Diarrhea or Pain occur.
If the Vomiting is accompanied by blood or the dog shows signs of Dehydration, such as sunken eyes, dry gums, or decreased skin turgor, a veterinarian should be consulted immediately. These symptoms may indicate a serious illness or an acute emergency.
Vomiting should also be taken seriously in young puppies, older dogs, or animals with existing health problems and clarified by a veterinarian as soon as possible, as these animals are more susceptible to complications.
Symptom recognition for the pet owner and veterinary diagnostic procedure
It is important for the pet owner to observe the dog’s behavior closely in order to recognize symptoms early. Pay attention to the frequency and timing of vomiting, as well as other changes in the dog’s behavior or appearance.
During the veterinary visit, the veterinarian will perform a thorough medical history to narrow down the possible causes of the Vomiting. This includes asking about the feeding routine, the type of food, possible changes in the environment or stress factors, and previous illnesses.
Following the medical history, the veterinarian may perform a physical examination and, depending on the suspicion, order further diagnostic tests. Blood tests can help identify infections or organ problems. X-rays or ultrasound examinations can make foreign bodies in the digestive tract or structural abnormalities visible. In some cases, endoscopy may be necessary to directly examine the lining of the esophagus or stomach.
What the pet owner can do and professional therapy options
As a first measure, the pet owner should temporarily give the dog no food to calm the stomach. A fasting period of 12 to 24 hours can be helpful to give the digestive system a break. However, it is important that the dog has access to fresh water at all times to avoid Dehydration.
After the fasting period, the pet owner can offer the dog small, easily digestible meals. Cooked rice with chicken or special diet food recommended by the veterinarian are suitable for this purpose. This bland diet should be fed in small portions throughout the day to avoid overloading the stomach.
Stress reduction can also help reduce Vomiting. Make sure the dog eats in a calm and stress-free environment. Avoid sudden changes in the feeding routine or daily routine that could upset the dog.
In the long term, it can be helpful to adjust the dog’s feeding habits by giving smaller portions throughout the day to reduce the risk of stomach diseases. Use slow feeders or special food bowls that prevent gulping.
If the vomiting persists or other symptoms occur, the pet owner should not hesitate to consult the veterinarian again to discuss further diagnostic tests or treatments. Early intervention can prevent serious complications and protect the dog’s health in the long term.
Outlook on current research
Current research considers regurgitation of undigested food in dogs as a symptom that may indicate various underlying problems. Studies focus on understanding the mechanisms that lead to this specific Vomiting. An important aspect is the distinction between Vomiting and regurgitation, as both can have different causes but show similar symptoms. Researchers are working to develop better diagnostic criteria to help veterinarians distinguish between these two conditions and treat them accordingly.
Another area of research is investigating the role of feeding habits and the food itself. Some studies suggest that certain ingredients or additives in food may increase the risk of vomiting. It is also being investigated how feeding frequency and the amount of food affect the dog’s digestive system. Experiments with different types of food, such as hypoallergenic diets or easily digestible feeds, are being carried out to determine whether these diets can reduce vomiting.
The genetic predisposition for regurgitation of undigested food is also a research field of interest. Some dog breeds appear to be more susceptible to this symptom, suggesting that genetic factors may play a role. The identification of specific genetic markers could in the future facilitate the diagnosis and treatment of dogs prone to this symptom. Researchers are working to create genetic databases that could help to better understand risk factors.
In therapy development, new approaches are being developed to control Vomiting and improve the quality of life of affected dogs. This includes both pharmacological and non-pharmacological approaches. New medications that specifically address the causes of Vomiting are in development. At the same time, alternative therapies such as acupuncture and herbal medicine are being investigated to evaluate whether they may play a supportive role in the treatment.
Long-term studies are underway to understand the effects of chronic Vomiting on the overall health of dogs. This research aims to capture the long-term effects on the digestive system, nutrient absorption and well-being. These findings could lead to new prevention strategies and treatment approaches that address not only the symptom but also the underlying cause.
