Touching Japanese Movie

I was able to watch a Japanese movie the other night about a young girl who wants to have a dog. When her parents approved to grant her request, her mother ask her to make 10 promises for her dog named socks. It was so touching and moving. I cried when the dog died due to old age and when the 2 of them were able to fulfill their promises though they sometimes forget them. The dog which is a golden retriever became very loyal to her upto the last moment.
