It was based on a newly married couple. Then they have a little girl and how Enzo the dog bonds with each one of them in different ways.
The story is told by Enzo the dog's point of few. It showed the perpective of how the family is viewed from a dog's point of view.
Enzo tried to comfort and help each member of the family. He wanted to be there to support them and help any way he could. He wanted everyone to be happy. I loved reading about how a dog might actually think about what humans do.
I did not enjoy the details of the racing. Some parts were really enjoyable while other drug on forever. I hated reading about the custody battle between the Denny and the grand parents.
Denny was a race car driver. He married the love of his life and was so thrilled to have a new baby daughter. He dog, Enzo, went thru each faze of his life and grew to love each member of the family. Enzo loved to racing with Denny and enjoyed being on the race track and going fast.
