Parvovirus, commonly known as parvo, is a highly contagious viral infection that primarily affects dogs. The survival rate for dogs with parvo greatly depends on several factors, including the dog's age, overall health, and how quickly treatment is sought.

1. **Age**: Puppies are particularly vulnerable to parvo, especially those between 6 weeks and 6 months old. They have immature immune systems, making it harder for them to fight off infections. Adult dogs, especially those that are fully vaccinated, have a higher chance of survival.

2. **Vaccination Status**: Vaccinated dogs have a significantly lower risk of contracting parvo and, if they do, often experience milder symptoms. Vaccination is crucial, and it's recommended that puppies receive their vaccinations on schedule, typically starting at 6-8 weeks of age.

3. **Prompt Treatment**: The sooner a dog receives veterinary care after showing symptoms of parvo (such as vomiting, diarrhea, lethargy, and loss of appetite), the better their chances of survival. Treatment usually involves aggressive supportive care, including intravenous fluids, medications to control vomiting and diarrhea, and sometimes antibiotics to prevent secondary infections.

4. **Overall Health**: Dogs with pre-existing health conditions or weakened immune systems may have a harder time fighting off the virus. A healthy dog with no underlying health issues will have a better chance of survival.

In summary, while not all dogs will survive parvo, many can recover with timely and appropriate veterinary care. The key is prevention through vaccination and early intervention if symptoms arise.

Always consult your veterinarian for personalized advice and to keep your dog healthy and safe from parvo.
