ONE GOOD DOG tells the story of Adam March and the dog who helps him regain his humanity. Adam is by any measure a success--high level job, a beautiful wife, expensive cars, exclusive home, spoiled daughter. But Adam has a secret. Far from being of the privileged class that he now moves in, Adam comes from a boyhood spent in foster care; a father who has given him up, and runaway sister. He has scars that he bears to no one.

When a mistake by his administrative assistant threatens to expose his past, in trying to save his present, Adam loses everything.

Divorced, jobless, and doing community service in a homeless shelter, Adam acquires a street dog, a pit bull mix who has a difficult background of his own.

This pair learn about trust--and the true meaning of what it means to be human.
