Gastroenteritis in dogs is a frequent illness characterized by inflammation of the gastrointestinal system, particularly the stomach and small intestine. This article will discuss the causes, symptoms, diagnosis, and treatment of gastroenteritis in dogs.

Gastroenteritis, or digestive system inflammation, is a frequent illness that affects dogs of all ages and breeds. While many cases of gastroenteritis in dogs are mild and self-limiting, others can be severe and necessitate medical attention. 

This article will go through the causes, symptoms, diagnosis, and treatment of gastroenteritis in dogs, as well as measures for preventing this ailment in your canine companion. 

Causes of Gastroenteritis in Dogs

Canine gastroenteritis can result from a number of causes, such as:

  • Infections: Bacterial, viral, or parasite diseases can cause gastroenteritis in dogs. Salmonella, E. coli, Campylobacter, and Parvovirus are typical offenders.

  • Dietary transgression: If dogs eat rubbish, table scraps, or other non-food things, they run the risk of developing gastroenteritis.

  • Dietary modifications: Sudden changes in diet or eating a low-quality diet might cause gastroenteritis.

  • Intestinal parasites: Intestinal parasites such as roundworms, hookworms, and giardia can cause gastroenteritis.

  • Inflammatory bowel disease: Chronic inflammation of the intestinal tract, often caused by an abnormal immune response, can lead to gastroenteritis.

  • Stress: Stressful events, such as travel or boarding, can cause digestive upset in dogs.

  • Toxins: Ingestion of toxic substances, such as certain plants, household chemicals, or medications, can cause gastroenteritis.

Dog Stomach Infection Symptoms

Various symptoms of dog gastrointestinal disorders include the following:

  • Vomiting: Dogs with gastroenteritis may regularly vomit or have trouble swallowing.

  • Gastroenteritis: Gastroenteritis can produce loose, watery feces that occasionally contain blood or mucous.

  • Appetite loss: Dogs suffering from gastroenteritis may refuse to eat or display a diminished desire for food.

  • Lethargy: Dogs may display signs of weakness, exhaustion, and decreased activity.

  • Dehydration:  Dehydration can cause dry gums, sunken eyes, and a lack of suppleness in the skin in dogs.

  • Abdominal pain: Dogs with gastroenteritis may exhibit panting or restlessness as well as other symptoms of gastrointestinal pain.

  • Fever: Dogs who have gastroenteritis may develop a fever.

  • Behavior modifications: When dogs are experiencing stress, they may act differently.


Dog gastrointestinal disorders are often diagnosed using a combination of physical examination, medical history, and diagnostic tests. The following procedures may be performed by the veterinarian:

  • Physical examination: The veterinarian will check your dog's belly for indications of pain, swelling, or discomfort.

  • The veterinarian will inquire about your dog's nutrition, immunization history, and recent exposure to parasites or other dogs with gastrointestinal issues.

  • Fecal analysis: A fecal sample can be collected and examined to see whether there are any parasites, bacteria, or viruses present.

  • Blood tests: Blood tests may be performed on your dog to examine its overall health and look for signs of dehydration, electrolyte imbalances, or inflammation.

  • Imaging: In some cases, imaging studies such as X-rays or ultrasound may be recommended to rule out other causes of gastrointestinal symptoms, such as foreign objects or intestinal obstructions.

  • Endoscopy: Endoscopy may be recommended to allow direct visualization of the digestive tract and to obtain biopsy samples for further evaluation.

Treatment for Dog Gastroenteritis

The severity of the ailment and the root cause will determine the course of treatment for canine gastroenteritis. Treatment options include:

  • Fluid treatment: Dogs with gastroenteritis may get dehydrated; thus, fluid therapy (intravenous or subcutaneous fluids) may be required to keep them hydrated and maintain a healthy electrolyte balance.

  • Anti-nausea medication: Medications such as maropitant or Metoclopramide may be recommended to alleviate nausea and vomiting.

  • Bland diet: To give the digestive system time to heal, a bland, readily digested diet may be advised.

  • Probiotics: Supplements with probiotics may help the gut's healthy bacterial balance return.

  • Antibiotics: If bacteria are the cause of the gastroenteritis, antibiotics may be recommended.

  • Medication to treat intestinal parasites: If intestinal parasites are found, medication to treat them may be administered.

  • Treatment for symptoms: Drugs like painkillers or anti-diarrheal medications can be used to control symptoms.

How to Prevent Gastroenteritis in Dogs

You may help avoid gastroenteritis in dogs by doing the following things:

  • Vaccination: Make sure your dog has had all of his or her immunizations, especially those for common viral diseases like Parvovirus and Canine Distemper.

  • Good hygiene: Good hygiene includes washing your hands frequently and keeping your dog's food and water bowls clean.

  • Parasite prevention: Make sure your dog is on a regular parasite prevention program to help avoid intestinal parasites, including roundworms, hookworms, and giardia.

  • Diet: Feed your dog a well-balanced food suited for their age and health level, and avoid drastic dietary changes.

  • Avoid hazardous items: Keep poisonous things such as home cleansers, human medications, and some plants out of your dog's reach.

  • Exercise and socializing: Exercise and sociability can assist dogs in reducing stress, which can be a trigger for gastroenteritis.

  • Regular veterinary checks: Regular checkups with your veterinarian can help identify and address any health concerns before they become serious.

Following these precautions may lessen the likelihood of your dog having gastroenteritis and other health issues. If you observe any symptoms of disease in your dog, get veterinarian treatment as soon as possible to ensure that any health concerns are handled.
