I really like your use of description words. I felt like I could picture the scene very well. I also liked the indecision the narrator expressed when wondering should he open the door and get the leash. It was a familiar backdrop to show indecision which I enjoyed. It also helped that the poem was told from the first person point of view as that made an even more immersive choice.
Overall, I think this poem did a very good job both setting the scene and conveying the narrators emotion all within a compressed structure, and because of all of that plus the lightheartedness of it all, I really enjoyed it!
