Symptoms of gastroenteritis in dogs typically include vomiting and diarrhea, and an examination of the feces or vomit can sometimes indicate the cause of the problem. If there are foreign objects like bones, grass, or bits of non-food items, your dog may have swallowed something disagreeable. If the vomit is dark, it may indicate internal bleeding. Dark, tarry feces can also indicate gastrointestinal bleeding. Watery diarrhea often means a problem with the colon. Blood in feces may mean a problem in the colorectal area. Your vet will be able to rely on samples and tests to determine the exact cause. Here are a few other symptoms that accompany gastroenteritis.

  • Dehydration (from fluid loss due to diarrhea and vomiting)
  • Nausea
  • Foamy bile in vomit
  • Dry heaving or gagging, especially after eating or drinking
  • Abdominal tenderness
  • Low-grade fever
  • Depression
  • Lethargy
  • Loss of appetite
  • Weight loss (if the condition┬ápersists)

Treatments for gastroenteritis in dogs vary widely depending on the underlying cause of the inflammation or irritation of the stomach and intestines. In the case of dietary indiscretion, your vet may recommend withholding food for 24 to 48 hours. Keeping your dog hydrated after loss of fluids due to diarrhea and vomiting is important. Depending on the severity of your dog’s dehydration, a veterinarian may recommend intravenous fluids to replenish electrolytes and hydration.

For infections, your veterinarian may prescribe medication and advise that you monitor the situation closely at home, making sure that your dog only gets small amounts of bland food and plenty of water. Some conditions, such as Addison’s disease or thyroid disorders require long-term treatment and monitoring. Cancer may require chemotherapy or surgery. Your veterinarian can recommend the correct course of treatment after forming a proper diagnosis. You should follow your veterinarian’s instructions closely.
