What is Parvo Virus in Dogs?
Canine Parvovirus (CPV), commonly known as Parvo, is one of the most dangerous and contagious viral diseases affecting dogs, especially puppies. The virus attacks rapidly dividing cells in the intestines and bone marrow, leading to severe gastrointestinal illness, dehydration, and a weakened immune system. Puppies and unvaccinated dogs are at the highest risk.
Without prompt veterinary treatment, Parvo can become life-threatening within a short period.
How Does Parvo Spread?
Parvovirus spreads primarily through contact with infected feces. However, direct contact with feces is not necessary for infection. The virus can survive on contaminated surfaces, food bowls, water bowls, shoes, clothing, kennels, and outdoor environments for extended periods.
A dog can become infected by:
- •Sniffing contaminated ground
- •Contact with infected dogs
- •Sharing bowls, toys, or bedding
- •Visiting contaminated parks or public areas
- •Contact with contaminated human clothing or footwear
Dogs Most at Risk
- ⚠️Puppies between 6 weeks and 6 months of age
- ⚠️Unvaccinated dogs
- ⚠️Partially vaccinated puppies
- ⚠️Dogs living in shelters, kennels, or crowded environments
- ⚠️Dogs with weakened immune systems
