If the dog has not eaten for a long time, it will cause excessive stomach acid and cause vomiting. It is recommended to feed a small amount of easily digestible food and water, and feed it regularly and quantitatively every day. If a dog accidentally eats a foreign body, the foreign body blocks the gastrointestinal tract and causes vomiting of yellow water. It is recommended to take the dog to the hospital for a X-ray to determine the location of the foreign body and then remove it.

If your dog has been vomiting yellow water for several days in a row, it is likely to be suffering from gastroenteritis. Mild gastroenteritis will occasionally vomit yellow water. In severe cases, the dog may vomit several times a day and keep vomiting for several days, unable to eat at all. The dog should be taken to the pet hospital for examination in time.
