My Partner, My Dog, My Do-do

Do-do was born in my home. His mother delivered three puppies in the evening. He was the smallest one in his brothers and sisters. After they were three months old, we sent other puppies to my relations except Do-do. Do-do was very mischievous and active. When I spoke to him, he always looked at me with his big cute eyes and wagged his tail. He always accompanied me, no matter I was happy or depressed. Two years ago, he was very sick. He died after I came home. I really miss him until now.
