To the best of my knowledge, no - I can't think of a viral respiratory illness in which the same virus infects both humans and dogs. Both humans and dogs can become sick with influenza, but the viruses are different (humans tend to get H1 and H2 versions while dogs currently have an H3N9 version running around).
The dogs do it to make them sick to get the virus out of there stomach just leave them too it it wont do them any harm
Yes, well water can sometimes make you sick. All well water should be lab tested before consumption by humans.
