Dogs often vomiting yellow water with foam may be caused by gastrointestinal diseases. It is best to go to the hospital for examination in time. Frequent vomiting of yellow water indicates that the condition is serious. If not treated in time, the condition will be delayed and worsened. Pay more attention when feeding your dog. Do not feed your dog hard, irritating, or spicy food that is difficult to digest. Do not feed your dog raw meat. Feed probiotics or gastrointestinal supplements regularly to promote digestion.
