Colourful Dog

You’re soft as a newborn lamb with warm wool,
A non-living object that is fun to play with,
Big like an old computer and a plant falling down to the ground,
You make me happy when I’m sad,
Black like an old coin,
White like a glue stick and brown like a dead leaf that has fallen off a tree,
It shakes as a rattlesnake slithering across the land,
If you were alive it would be like a wolf howling at the moon all night,
You’re so special to me.
