Coal tar is one of the first known human carcinogens. As a general rule, anything that causes cancer in one species of mammals will also cause it in other species of mammals.
However, coal tar shampoos can be an effective treatment for some skin diseases. I wouldn't use it on a dog that doesn't have a diagnosed skin disease that's responsive to coal tar. And if the dog does have a skin disease, I'd try the other medicated shampoos first, and resort to coal tar only when all else fails. And I'd be sure to wear gloves when using it.
