Generally, dogs vomiting yellow water in the middle of the night are hungry. Parents can prevent this from happening by giving the dog some food before going to bed. Some dogs may catch a cold in the middle of the night and irritate their intestines and vomit yellow water. Parents should prepare a warm nest for the dog, so that it will not catch a cold in the middle of the night and vomit yellow water.

Tip:

Viral infection can also cause dogs to vomit yellow water in the middle of the night. Parents are best to get tested for infectious diseases to rule out viral infection. If your dog is found to be infected with the virus, it should be treated as soon as possible.
