Is this the cutest boy and his dog?
Little Buddy has formed such a strong bond with his dog Reagan that his foster family is producing a book of their photographs together.
From having a bath to enjoying a swing, Buddy and his furry friend do everything together and have attracted more than 100,000 followers on Facebook.
The little boy's foster grandmother, Sandi Swiridoff, is selling the book to raise money for a charity that works with foster families.
As she said: 'The touching, true story of Reagan and little Buddy needed to be told. I couldn't keep all the adorableness to myself.'
Sandi and her husband Eric adopted Reagan when he was eight weeks old as a way to cope when their daughter had to give up her first two foster children.
Buddy has been with their daughter for nearly two years since he was 11months.
As Sandi says: 'Adopting Reagan was one of the best decisions we've ever made. He has added so much joy to our lives, and to the lives of many other people.'
