I bought a used paperback version of the book, and I thoroughly enjoyed reading it. However, as often happens, the movie version is "enhanced" so that the story has a few extra twists and turns. I'd say, read the book first. Then be sure to see the movie, too. One reviewer said that My Dog Skip should be on the same shelf with The Adventures of Tom Sawyer. I tend to agree, and that's high praise. Whether you love dogs or not, you'll enjoy this heart-warming story.
The book is available on Amazon.com.
So is the DVD.
My Dog Skip (Keepcase)
If you live near me, I'll lend you my copy of the book.
