This Kid is a Golden Retriever

I was speaking with one of my classmates yesterday and she mentioned that she thought the student presenting his project was really cute. We talked about how he wasn't really either of our types but that he was someone that you wanted to like just because of his bubbly bouncy personality and classic preppy looks. And then it hit me. This kid is a golden retriever in human skin. He practically had his tongue lolling out of his mouth when he smiled. So now I wonder: What Kind of Dog am I?
