Also this asian film called quill I cried very hard on, because I love dogs and have had dogs involved with me since I can remember. here is the summary:
As a labrador puppy, Quill is sent to live with a couple, Isamu (Teruyuki Kagawa) and Mitsuko Nii (Shinobu Terajima), who work as volunteers, training guide dogs (seeing eye dogs). When he grows to an adult dog, he is taken to a guide dog school, by a friendly, yet firm trainer Satoru Tawada.
Although Quill is a little slower than the other dogs at the school, he seems to have an unusual 'empathy' and remarkable patience with his trainers. Tawade decides that Quill would be the ideal guide dog for Mitsuru Watanabe (Kaoru Kobayashi), but Wanatabe, a lonely and ill-tempered middle aged man, isn't as enthusiastic - he would "would rather sleep than be dragged around by a dog.".
From here, the story is narrated by Wanatabe's daughter, Mitsuko (Yukika Sakuratani), and slowly, Wantanbe is rehabilitated, venturing into the outside world, and learning, not only to trust other humans, but the animal at his side who guides him.
