A dog that suddenly vomits thick foam may be caused by improper diet, indigestion, gastroenteritis, pancreatitis, viral infection, or poisoning. It is best to take the dog to the pet hospital for examination and treatment immediately. Avoid delaying the condition and risking life.
Tips:
You need to pay more attention to your dog's diet and do not feed your dog randomly to avoid indigestion. And don’t give your dog random human food to avoid poisoning.
