I saw part of a movie the other day. Older british men talking together in the evening. One man is telling stories of when he was a dog. When he was a dog his name was wags. He talked about being bathed and how it changed how he smelled so he was different to his dog friends. The talked about one day he had an adventure with his dog friend and chased a horse and a flock of sheep. They had a great day and on returning home in the evening wags was shot. The movie was based on a book. Does anyone know the name of this movie?
