Status Updates From Shiloh (Shiloh, #1)

I am reading it in school and so far it is going good.

A boy went on a walk with his gun shooting still stuff not alive. While he was on his walk a dog showed up and walked at a distance from him and every time the boy stopped the dog stopped. So he sat on a log to see if the dog would come but unfortunately the dog didn't come. So he started to walk again and the dog started too. Then he thought of an idea he patted his thigh and the dog came to lick his fingers.
