Diarrhea and vomiting in dogs are usually caused by the following three aspects:
- Indigestion: The first possible cause is overeating, which leads to indigestion in the gastrointestinal tract.
- Ingestion of Foreign Objects: The second possibility is the ingestion of foreign objects, such as “gloves,” “stones,” or “plastic bags.”
- Parasites or Gastrointestinal Cold: Thirdly, there may be parasites in the stomach, or the gastrointestinal tract may have been exposed to cold.

Measures to Address Diarrhea and Vomiting in Dogs
When a dog exhibits the following conditions, feeding should be stopped first to reduce the digestive burden on its gastrointestinal tract.
Management of Indigestion
If the cause is simply overeating leading to indigestion, probiotics can be administered to the dog, and the amount of food for the next two meals should be controlled. Usually, the dog will self-regulate and recover.
Supportive Treatment for Gastroenteritis
If the dog has gastroenteritis, you can provide drugs such as “gentamicin,” “montmorillonite powder,” and “KeLITai” (a specific medication) as auxiliary treatments.
Detection and Treatment of Parvovirus
If a puppy under four months old exhibits vomiting of white foam and diarrhea, with a small amount of blood in the feces, it is recommended to use a test strip to check for “parvovirus” infection. If the test result indicates a parvovirus infection, intravenous fluid therapy should be administered.
Management of Foreign Object Ingestion
If the problem is caused by the ingestion of a foreign object, in most cases, the dog will vomit or pass the object on its own, unless the object is particularly large. In such cases, it is recommended to take the dog to a veterinary hospital for an X-ray examination.
Preventive Measures
Finally, it is essential to deworm dogs regularly, regardless of their size. Whether it is a large dog or a small dog, one should not wait until the dog develops a problem before seeking treatment. This not only causes suffering to the dog but also wastes money.
