Dogs with regurgitation are also called parvotrophies. During the onset period, they will have symptoms such as vomiting, diarrhea, and difficulty breathing. They should be sent to the pet hospital for examination and treatment immediately to avoid aggravation of the condition and life-threatening consequences. During the treatment period, be careful not to go out for the dog. Give the dog anything to eat. When the condition gradually improves, you can feed the dog nutritional cream and goat milk powder to help relieve the condition. Regularly prevent and deworm the dog to enhance the body's immunity.
