Dogs and Vomiting Undigested Food: A Guide to Causes and Treatment Options

If your dog is vomiting undigested food, it's natural to feel concerned and wonder what's going on.

This behavior can be a sign of gastrointestinal issues, such as food allergies, sensitivities, or gastrointestinal foreign bodies.

Some common causes of vomiting undigested food in dogs include eating spoiled or contaminated food, eating too quickly, or having a food allergy.

Dogs may also vomit undigested food if they have a gastrointestinal foreign body, such as a swallowed object or a blockage in the digestive tract.

In some cases, vomiting undigested food can be a symptom of a more serious underlying condition, such as pancreatitis or gastrointestinal cancer.

If your dog is vomiting undigested food, it's essential to consult with a veterinarian to determine the underlying cause and develop a treatment plan.

Some common causes of vomiting in dogs include diet change, intestinal parasites, viral infection, medication reaction, bloat, and bacterial infection. If your dog vomits after being outside in the hot sun, heatstroke is a prime suspect. If your trash can displays evidence of canine exploration, then garbage, toxins, or a foreign body are more likely.

Vomiting can also be caused by primary gastrointestinal disorders or systemic disorders. If your dog is vomiting with diarrhea or vomiting with a poor appetite, call your veterinarian immediately. Persistent vomiting, which can be a sign of a more serious health problem, may be a sudden, repeated retching and vomiting of frothy and clear fluid.

In some cases, vomiting can be caused by a foreign body, which is the general term for something a dog swallows that can't pass through the digestive system. If your dog is vomiting on an empty stomach, it could be due to empty tummy syndrome or irritation from stomach acid that collects when the stomach is empty for too long.

Diagnosis and treatment of vomiting in dogs can be a complex process, but it's essential to determine the underlying cause of the vomiting to provide effective treatment. Your vet will likely recommend a combination of diagnostic tests and treatments based on the severity of the vomiting and your dog's overall health.

If your dog is vomiting undigested food, your vet may recommend withholding food for a short period (12-24 hours) and then reintroducing a bland diet fed in small regular meals. This can help to settle the stomach and reduce vomiting. Water should not be withheld from vomiting dogs, but should be offered in small regular amounts.

Your vet may also recommend further investigations, such as blood tests, a diet trial, radiographs (X-rays), ultrasound, endoscopy, biopsies, fecal samples, or urine samples, to determine the underlying cause of the vomiting. These tests can help to identify systemic disease, food allergies, obstructions, or other conditions that may be contributing to the vomiting.

Symptomatic treatment may also involve fluid therapy, medications, or surgery to address underlying conditions and prevent dehydration, electrolyte imbalances, and acid-based disorders.

Diagnosing the cause of your dog's vomiting is a crucial step in determining the best course of treatment. Your veterinarian will ask you questions about your dog's access to garbage, poisons, and toxins, as well as any recent dietary changes. They'll also want to know if your dog is exhibiting any other symptoms.

To narrow down the cause, it's essential to provide your veterinarian with as much information as possible. If your dog has been vomiting after being outside in the hot sun, heatstroke is a prime suspect. If you've noticed your trash can has been explored, garbage, toxins, or a foreign body are more likely.

Your veterinarian will perform a physical examination and may recommend additional tests, such as blood work, ultrasounds, X-rays, endoscopic evaluations, biopsies, and urine tests. Blood tests can help investigate systemic diseases like kidney or liver disease, while a diet trial can be used to diagnose food allergies.

Here are some common diagnostic tests used to determine the cause of vomiting:

Your veterinarian will examine your dog and, depending on the information you provide and the findings of the clinical exam, may recommend treating your dog symptomatically or further investigations.

When your dog's vomiting persists, it's essential to consider fluid therapy if they're unable to keep food or water down. This is because dehydration is a significant risk, and fluid therapy in hospital may be necessary.

Symptomatic treatment can be started initially, which involves withholding food for 12-24 hours and then reintroducing a bland diet in small regular meals. Water should not be withheld, but offered in small regular amounts.

Changing the diet to a bland, highly digestible food can help settle the stomach. Royal canine gastrointestinal or sensitivity control foods are suitable options, but home-cooked diets of plain boiled chicken or white fish can also be helpful for a short time.

If vomiting continues or recurs when food is reintroduced, your pet should be seen by the vet again. This is crucial for identifying the underlying cause and preventing further complications.

Other treatment options include medications, such as anti-emetics and antacids, which can be prescribed by your vet based on the cause and your dog's condition. In some cases, surgery may be necessary to remove obstructions, such as ingested toys or masses.
