Is there a story between you and your pet?or any interesting things?

I think most of people have stories with their pets. Normally pets are so cute and bring a lot of happiness to us. I recalled when I was 8 years ago, my dog 'Feihu' disappeared from this world! oh! my, my heart is almost broken! I searched for him many days and called his name aloud, but he never came back. I didn't know why my 'Feihu' left me without a word? what happened to him? That made me so so sad.
