Canine parvovirus is a highly contagious viral disease that can affect all ages but causes a serious life-threatening disease in young puppies. This virus attacks the replicating cells in the intestine causing severe bloody diarrhoea, uncontrollable vomiting, loss of appetite, and a fever. Dogs can die from severe malnutrition and dehydration despite intensive veterinary care. It is not necessary to have direct contact with other dogs for the disease to be spread. The virus is highly resistant and can persist in the environment for many years. This is why we recommend that your puppy stays away from public areas until they are fully vaccinated.
