Dog got a parvo shot last year, but seems sick like it's parvo symptoms now—could they still get infected?

My dog was vaccinated against parvo last year, but I've noticed they're displaying symptoms similar to parvo today, like lethargy and a lack of appetite. I thought the vaccine would protect them, but now I'm worried they might be infected. Is it possible for a vaccinated dog to still contract parvo, and should I take them to see a vet right away?

Answer

While vaccinations greatly reduce the risk of contracting parvovirus, they do not guarantee complete immunity. A dog displaying symptoms such as lethargy and a lack of appetite should be evaluated by a veterinarian.

  • Vaccines significantly lower the risk but don't provide 100% protection.
  • Symptoms like lethargy should be taken seriously.
  • Prompt veterinary evaluation is recommended for concerning symptoms.

Parvovirus vaccination is crucial in protecting your dog, yet no vaccine can provide complete immunity. Sometimes, a vaccinated dog may still show symptoms due to different factors such as an incomplete immune response or a particularly strong strain of the virus. It is important to consult a veterinarian to assess your dog's condition and determine the best course of action.

If this is an emergency, please seek immediate veterinary care.
