Parvovirus in dogs is a nasty and life-threatening infectious disease. It’s particularly dangerous for puppies and unvaccinated dogs. 80% of unprotected dogs will not survive without intensive veterinary care. 10-30% will still not survive despite treatment. Vet-approved vaccines are the only safe and effective way to protect your dog against parvovirus.

Parvovirus is spread via the poo of infected dogs. The virus is extremely hard to kill and hangs around in the environment for years. You can even carry it into the house on your own feet or hands. Symptoms begin when the virus attacks your dog’s intestine and immune system. The main symptom is severe and bloody diarrhoea. The condition gets worse very quickly. Early identification and intensive treatment offer the best chance of survival.
