If a dog is vomiting white foam, Pet Health & Care recommends keeping the dog off food for 12-16 hours to allow his stomach to settle. If the dog is vomiting the substance in the morning, it's possible he is suffering from bilious vomiting syndrome, or the presence of an excessive amount of bile in the stomach. If this is suspected, the dog should be taken to the vet for a diagnosis.
According to Vetinfo, other possible causes of white foamy vomit include inflammatory bowel disease, bloat or kennel cough. Vomiting due to kennel cough is typically accompanied by a dry cough, runny eyes or nose and lethargy.
