In a press statement issued on December 11, 2025, RSPCA NSW, the not-for-profit animal welfare organisation operating across New South Wales, called on the Illawarra community to help stop the spread of Parvovirus and keep pets safe following several confirmed cases in the area. Here is everything dog owners need to know about Canine parvovirus outbreak in Illawarra and how to save their dogs from it, as guided by the RSPCA.
What is parvovirus?
Parvo is a serious and often fatal viral disease affecting dogs and puppies of any age. It spreads through direct or indirect contact with faecal matter from infected dogs, including contaminated ground, shoes, or surfaces. Because the virus is invisible and long-lasting, dogs can be exposed even after an infected animal has left an area.
How to know if your dog is sick from parvovirus
Symptoms usually appear 4–6 days after exposure and may include:
- Vomiting (often with blood)
- Diarrhoea (often with blood)
- Loss of appetite
- Lethargy or weakness
- Dehydration
Without treatment, up to 91% of infected dogs may die, the not-for-profit animal welfare organisation noted.
What to do if you suspect parvo
- Seek veterinary care immediately — early treatment greatly improves survival chances.
- Call the vet before arriving to alert them to possible Parvo symptoms.
- Do not enter the clinic with a suspected case; wait in your car and follow staff instructions to prevent spread.
How to protect your dog
- Ensure your dog is up to date with C3 vaccinations.
- Puppies should receive a full primary vaccination course.
- Avoid parks and public grassy areas if your dog is unvaccinated.
- Keep unvaccinated dogs away from other dogs for at least 10 days after vaccination.
Cleaning and disinfection
Parvo can survive on surfaces, clothing, and objects for months or years.
- Dispose of contaminated bedding and toys
- Clean surfaces thoroughly, then disinfect using bleach diluted in water (1 cup bleach to one bucket of water)
- Wear gloves and wash hands well after cleaning
- Consult your vet for alternative disinfectants if bleach can’t be used
