Parvo is an infectious disease caused by viral infection. Clinically, the main reason why dogs are infected with parvo is exposure to items contaminated with parvovirus. Improper daily diet of dogs is also the main cause of common small diseases.

After dogs are infected with parvovirus, the early symptoms are mainly symptoms such as loss of appetite and soft stools, which can easily be confused with ordinary gastroenteritis. When the disease develops 1-2 days later, severe vomiting and diarrhea will occur, accompanied by varying degrees of bloody stools. It is recommended to consult a professional pet doctor in time.
