My Puppy Has Parvo: What Should I Do?

Recognize the warning signs early

• Severe lethargy and weakness
• Repeated vomiting (often with bile or blood)
• Profuse foul-smelling diarrhea, frequently bloody
• Loss of appetite for more than 24 hours
• Fever or unusually low body temperature
• Rapid dehydration — gums look dry or pale

Step 1 — Call your vet immediately

Do not wait to 'see if they get better.' Call your veterinarian or the nearest emergency animal hospital and explain the symptoms. Tell them you suspect parvo so they can prepare an isolation room — parvo is extremely contagious to other dogs.

Step 2 — Isolate your puppy from other dogs

Keep your puppy away from any other dogs in your home and yard. Wash hands thoroughly after every interaction and change clothes before touching healthy dogs. Parvo can survive on surfaces for months and is resistant to most household cleaners — only diluted bleach (1:30 ratio) reliably kills it.

Step 3 — Hospitalization and supportive care

There is no specific cure for parvo. Treatment focuses on supportive care: IV fluids to combat dehydration, anti-nausea medication, antibiotics to prevent secondary infections, and close monitoring of blood sugar and electrolytes. Most puppies need 3 to 7 days in the hospital.

Step 4 — Recovery and disinfection at home

Once your puppy comes home, continue to isolate them from other dogs for at least two weeks. Disinfect bowls, toys, crates, bedding and floors with diluted bleach. Avoid public dog areas, parks and pet stores until your puppy has completed their full vaccination series and your vet gives the all-clear.

Prevention — the best medicine

Parvo is largely preventable through vaccination. The standard puppy series begins at 6 to 8 weeks and continues every 3 to 4 weeks until 16 weeks of age, with a booster at one year. Until your puppy is fully vaccinated, avoid dog parks, pet stores, sidewalks where many dogs walk, and any contact with unvaccinated dogs.
