I think that the orientation is the first paragraph,the author introduces the main character,this is the who,he brings in the setting,him leaving his house,this is the where,he also tells us what he is doing,taking out his dog,and why,because if he does not,the dog would pee at his doorstep.
“I breathed in the frigid air and smelled smoke.” this is when the action starts to rise.
“The smoke was coming from a burning building, and that psychotic pug thought it would be a good idea to run toward the fire. Smart guy.” When we read this, we will have that sense of danger as we understand that there’s a building on fire.
After that, the dog ran into the burning building, and the author chases it. This is the event that leads to the climax.
“I ignored the rude child and began yanking on the door. It was wedged shut for whatever reason and not budging.”
“I wrestled the dog free from the terrified kid’s pants and picked him up. That lousy little pipsqueak took that moment as an opportunity to finally relieve himself”
The author yanked the door save his dog,in doing so,he saved the class and the teachers. The author wrestled the dog ,saving the little boy that was rude to him before, all in a school on fire.
The author ends off the story by giving a “funny/ humorous” ending by saying it from the dog’s point of view. One example is “Good boys don’t pee on Daddy’s jacket.”
