why is dog vomiting white foam
Yet another reason dogs vomit white foam is because of kennel cough, which is an upper respiratory infection that is contracted from other dogs. Dogs suffering from kennel cough have a dry cough and experience flu-like symptoms, such as nasal discharge, sneezing and fever. Finally, vomiting white foam is a sign of rabies as well. The foaming around the mouth is caused by nerve damage around the mouth and throat, which prevents the dog from swallowing. However, dogs do not begin exhibiting this symptom until the later stages of the disease.
One of the most common reasons that dogs vomit white foam is because of an upset stomach. According to VetInfo, this often occurs if the dog drinks water too quickly, eats grass or ingests something inedible that upsets its stomach.
What does it mean if a dog is vomiting white foam? Another reason dogs vomit white foam is because of bilious vomiting syndrome, which usually occurs right after dogs wake up. Veterinarians believe that the syndrome is caused by too much stomach acid or other secretions that collect in the stomach and cause irritation.
