Beautifully written movie of the love of dogs and humans I've been waiting for over a year for the opening of this movie. After reading the book, which was fantastic, I heard the movie was being made. The movie had all I expected, and more. I laughed, I cried, I remembered past pets. As the title mentions, a dog's purpose, I had never really thought of that before. Each of our dogs has had a purpose. Our first rescue, he made my husband LOVE dogs. We will always be at least a "one dog household". The casting was spot on. Young Ethan, teen Ethan and Dennis Quaid, grown Ethan were all wonderful. The dogs used were entertaining, and loving on the screen. Josh Gadd's wonderful voice was the true voice of all the dog's. Thanks to the author, W. Bruce Cameron for writing such a wonderful book, and to his wife, and the woman the book was written for, for writing the screenplay! If you love dogs, animals of any kind, you would be missing out by not seeing this film. I'll be back again and again to see it!
