Kennel cough (Bordetella) is usually transmitted though the air or through fomites of infected animals cough or sneeze, or through contact direct. Usually manifests as a disease of the upper respiratory tract, however, if it gets too difficult one may develop a secondary chest infection. Most dogs do not need treatment and is usually self-limiting, but infected dogs should be quarentined of others to avoid spreading the infection. Parvovirus You can hire different ways … can live in soil for years (picked up by a dog sniffing the ground), clothing, etc., but not usually through the air. The organs that are infected with the intestinal tract vili, that becomes very badly damaged and inflamed which leads to very bloody, mucous diarrhea and severe dehydration. The puppies that survive this virus may have some stomach problems in the future and tend to be more "sensitive" stomachs. Adults who contract, which is not as common as the puppies who get it, they tend to do a little better (the prognosis is good) and rarely have lasting effects. Hope this helps
