Parvo in Puppies: Signs, Treatment and Prevention

Why parvo is so dangerous

Parvovirus attacks a puppy’s gut and immune system, and in unvaccinated puppies it is frequently fatal without fast, intensive treatment. It’s extremely contagious, survives a long time in the environment, and spreads through infected faeces — a puppy can catch it from ground an infected dog walked on weeks earlier.

This is one of the real reasons the puppy vaccination schedule matters so much, and why you keep an unvaccinated puppy away from public ground.

The warning signs

Watch for severe vomiting, bloody or foul-smelling diarrhoea, sudden lethargy, refusing food, and a distended or painful belly, usually in a puppy under six months. Parvo moves fast — a bright puppy in the morning can be gravely ill by evening. If you see these signs in an unvaccinated or partly-vaccinated puppy, treat it as an emergency and phone your vet immediately.

Early veterinary treatment dramatically improves survival, so hours matter.

Prevention is almost everything

Parvo is largely preventable with the standard puppy vaccination course — a series of shots finishing at around 16 weeks, with boosters after. Until the course is complete, keep your puppy off public ground and away from unknown dogs. Disinfect properly if you’ve had a parvo case, as the virus is stubborn.

The vaccine is cheap. Treating parvo — if the puppy survives — is not.
