After a dog is infected with parvovirus and develops diarrhea, the prognosis depends on many factors, including the dog's overall health, the severity of the disease, and timely treatment.

Parvovirus is a serious infectious disease, but even if a dog has symptoms of diarrhea, Rescue is still possible. The veterinarian will usually develop a treatment plan based on the dog's specific situation, which may include infusions to replenish fluids and electrolytes, use of antiviral medications, and control of vomiting and diarrhea.

The key to treatment is early intervention and supportive care. Timely treatment can improve a dog's survival rate, but it does not guarantee a cure. During treatment, your dog's body needs time to fight off the virus and recover.
