Pocket VetParvovirus in dogs
Parvovirus ('parvo') is a highly contagious, often fatal virus, especially in unvaccinated puppies. It needs urgent veterinary care.
What it is
Parvo attacks the gut lining and immune system, causing severe vomiting and bloody diarrhea that lead to dehydration and sepsis. It spreads through infected feces and contaminated environments and is largely preventable with vaccination.
Symptoms
- ●Severe, often bloody diarrhea
- ●Repeated vomiting
- ●Lethargy and weakness
- ●Loss of appetite
- ●Fever or low temperature
🔴 When to act now
- ●Suspected parvo is an emergency — go to a vet immediately
- ●Puppies can deteriorate within hours from dehydration
Treatment & management
There's no direct cure; treatment is intensive supportive care — IV fluids, anti-nausea drugs, and infection control, usually hospitalised. Survival improves greatly with early treatment. Vaccination is highly effective prevention.
