PORTLAND (NEWS CENTER Maine) -- Many of us understand the effects a family dog can have on us; they're here for only a short time, but they change us.

Chris Morin, a Maine author, captures the love and influence of animals through his book "Three Labs A Lifetime," a memoir of his family dogs.

He wrote it for his mother, who was struggling with the loss of their third family dog, but realized it could be something other families would read and relate to.
