What is Canine Gastroenteritis?

The most dangerous cause is Canine Parvovirus (CPV) — a highly contagious viral disease that kills rapidly, especially in unvaccinated puppies.

⚠️ Parvovirus survives in soil for up to 1 year. A puppy does not need to meet an infected dog to catch it — contaminated shoes, hands or grass are enough.

Signs of Parvovirus

  • Severe, bloody diarrhoea — often the first visible sign
  • Profuse vomiting — cannot keep water down
  • Extreme lethargy — puppy cannot stand or lift head
  • Complete loss of appetite

Vaccination Protocol

  • 6 weeks: DHPPi — Distemper, Hepatitis, Parvovirus, Parainfluenza
  • 9 weeks: DHPPi + Leptospirosis booster
  • 12 weeks: DHPPi + Rabies
  • 16 weeks: Final puppy booster + Kennel Cough
  • Annual: Booster + Rabies
⚠️ Do not take your unvaccinated puppy to dog parks, pet shops or public areas. Until the 12-week vaccine is complete, carry your puppy — do not let it walk on public ground.

Treatment if Infected

Intensive supportive care — IV fluids, anti-nausea medication, antibiotics. Survival with early treatment: 80–95%. Without treatment: less than 10%.
