A white dog with light brown markings has a stick in his mouth and his paws in the snow.
A black dog lays in the dirt on a hot day
The white dog is playing in the snow, whilst the black dog lays in the dirt to escape the heat.  Also the white dog has a stick, and light brown markings, so it is not a black dog.
