Is canine stomach flu contagious to humans?
There are many studies showing there is a chance that humans and dogs can give each other noroviruses, otherwise commonly known as the stomach virus. Noroviruses can be caused by contaminated food or water, an infected person, or touching contaminated surfaces. It has not been proven yet that canines can give stomach flu to humans. Although, it is very likely, as there have been many cases when canines and their owners have had stomach flu at the same time.
