I have a dog. My dog is small. She is two years. She is very fluffy.
This is a lap dog. Her name is Charlie. I love hanging out with her on
the street. My dog is very cheerful, kind and flexible. She loves to
run around on the grass. I love to feed his dog. I buy her food. My dog
sleeps on a mat near the door. Dog man's best friend. Everybody knows
it.
