Also called canine parvovirus or parvo, parvovirus is a highly infectious virus that affects dogs. It was first noticed in 1978 in Europe. It mainly affects a dog’s small intestines but in young puppies, it can also affect the heart. The disease attacks the small intestine lining, causing it to stop replicating effectively.
