We know the subject is a man and we know he went for a walk. Let’s add a few details without changing the idea of the sentence.
The old man put on his heavy coat, leashed his black dog, grabbed a flashlight and a poop bag, and went out into the cold for a walk.
The main idea remains the same, but now we know the age of the man, that his pet is a black dog, it’s cold and dark outside and he thinks the dog has to go to the bathroom.
It’s all in the DETAILS! We can now visualize the man and his dog on a walk in the cold night.
