Intractable vomiting in dogs refers to the repeated and uncontrollable expulsion of stomach contents, which lasts for an extended period and cannot be stopped by the dog.

Can Occur with the Following Diseases:

Basics and possible causes

Vomiting is a complex reflex controlled by the brain, particularly by the vomiting center in the brainstem. This reflex is triggered by various stimuli, including stomach irritation, neurological signals, or toxic substances. The goal of vomiting is to rid the stomach of harmful substances.

Intractable vomiting can be caused by a variety of factors, ranging from harmless to serious health problems. The most common causes include infectious diseases, digestive disorders, foreign objects in the gastrointestinal tract, poisonings, food intolerances, and chronic diseases such as organ failure.

A common cause is gastritis, an inflammation of the gastric mucosa that can be triggered by bacteria, viruses, fungi, or parasites. Certain medications can also irritate the gastric mucosa and cause vomiting. In younger dogs, infections with parvoviruses, which lead to severe gastroenteritis, are a known cause of intractable vomiting.

Foreign objects in the stomach or intestines, such as toy parts or bones, can also lead to intractable vomiting because they prevent the normal passage of food, thereby causing an intestinal obstruction. In such cases, surgery is often required.

In addition, systemic diseases such as kidney failure, liver disease, or diabetes mellitus can lead to intractable vomiting. These diseases affect the entire metabolism and can stimulate the vomiting center in the brain by the accumulation of toxins in the blood.

Typical accompanying symptoms

  • Dehydration: Intractable vomiting can quickly lead to fluid loss (dehydration), which is manifested by dry mucous membranes, sunken eyes, and general weakness.
  • Weight loss: With persistent vomiting, the dog may lose weight, as it cannot retain food or fluids in the body.
  • Apathy: The dog often appears lethargic and disinterested in its surroundings due to discomfort and lack of energy.
  • Abdominal pain: The dog may show signs of pain in the abdominal area, which can be manifested by a hunched posture or refusal to be touched.
  • Blood in vomit: In severe cases, the vomit may contain blood, indicating serious damage to the gastric or esophageal mucosa.
  • Frequent smacking or swallowing: These behaviors may indicate that the dog is trying to suppress the vomiting reflex.

When to visit the vet?

A veterinarian should be consulted if the vomiting persists for more than 24 hours or if it is accompanied by severe symptoms such as blood in the vomit, severe apathy, or signs of pain. Also, if the dog cannot absorb or retain fluids, this is an emergency.

In puppies, older dogs, or dogs with known pre-existing conditions, action should be taken more quickly, as they are particularly susceptible to complications from dehydration or nutrient deficiency.

If, in addition to vomiting, the dog starts vomiting after potentially ingesting toxic substances, such as certain plants, household cleaners, or medications, veterinary help should be sought immediately.

Symptom recognition for animal owners and veterinary diagnostic procedures

It is important for the pet owner to make accurate observations and report them to the veterinarian. Important information includes the frequency and appearance of the vomit, food intake in the last 48 hours, possible ingestion of foreign objects or toxins, and any other symptoms the dog is showing.

The veterinarian will perform a thorough clinical examination to assess the dog’s general condition. This includes palpating the abdomen, checking the mucous membranes for signs of fluid loss (dehydration), and measuring vital signs.

In addition, diagnostic tests such as blood tests, X-rays, or ultrasound examinations may be necessary to determine the exact cause of the vomiting. Blood tests can provide information about organ functions, while imaging studies can help identify foreign objects or abnormalities in the gastrointestinal tract.

What can pet owners do and professional therapy options

Before consulting the veterinarian, you should try to keep the dog calm and give it access to fresh water in small amounts to prevent fluid loss (dehydration). It is important not to try to force-feed the dog or give it medication without veterinary advice, as this may worsen the situation.

Avoid giving the dog food until the vomiting has subsided or a veterinarian has made an accurate diagnosis. In mild cases, a short fasting period (12-24 hours) can help calm the stomach.

Observe the dog closely to gather more information for the veterinarian. Note when the vomiting occurs, whether it is related to food intake, and whether other abnormalities in the dog’s behavior are observed.

It can be helpful to keep the dog in a quiet, darkened room to minimize stress that could promote vomiting. Make sure the dog is not left alone, as you may need to intervene if its condition worsens.

Outlook on current research

Intractable vomiting in dogs, also known as persistent or refractory vomiting, is a worrying symptom that can indicate a variety of health problems. The focus of current research is on identifying the underlying mechanisms that trigger this symptom. Researchers are investigating the role of gastrointestinal disorders, neurological triggers, and even immunological factors that can lead to intractable vomiting. Advances in imaging technology, such as the use of high-resolution ultrasound and magnetic resonance imaging, enable a more precise diagnosis of the underlying causes.

A significant area of research focuses on the microbial communities in the intestine and their influence on vomiting. The hypothesis is that an imbalance in the gut microbiota, also known as dysbiosis, can cause inflammation and trigger vomiting in dogs. Scientists are working to identify specific probiotic strains that could help restore a healthy microbiome and thus reduce vomiting.

Another promising area of research is the genetic susceptibility to intractable vomiting. Genetic studies aim to identify specific gene markers that are associated with an increased susceptibility to this symptom. This could enable personalized treatment approaches in the future that are tailored to the genetic profiles of individual dogs.

Advances in pharmacology also offer new opportunities for treatment. Researchers are investigating new drugs that specifically target the neuronal pathways that control vomiting, with the aim of developing more effective and safer therapies. These drugs could also help minimize the side effects of existing treatments.

In addition, the role of environmental factors and their contribution to intractable vomiting is being investigated. Studies suggest that certain environmental influences, including dietary changes and stressors, can play a significant role. Research in this area aims to develop strategies to minimize these risks in order to improve the well-being of dogs.

Overall, current research shows that intractable vomiting in dogs is a complex symptom with multifactorial causes. The combination of advances in diagnostic technology, genetic insights, and new therapeutic approaches promises to significantly improve the treatment and management of this symptom in the future.
