Family Quotes in A Dog's Purpose

How we cite our quotes: (Chapter.Paragraph)

Quote #1

One day it occurred to me that the warm, squeaky, smelly things squirming around next to me were my brothers and sister. I was very disappointed. (1.1)

Our narrator doesn't identify with members of his own species. Instead, he bonds more closely with humans, who become his real family. Do you think this is an accurate depiction of how dogs behave?

Quote #2

Though my vision had resolved itself only to the point where I could distinguish fuzzy forms in the light, I knew that the large and beautiful shape with the long wonderful tongue was my mother. (1.2)

Okay, perhaps our narrator does care for his dog mother. And what's a better description for a mom than "large" and "beautiful," with a "long wonderful tongue"? Put that in your mom's next Mother's Day card.

Quote #3

I couldn't see that my brothers and sister had any purpose whatsoever. (1.2)

We're back to seeing our narrator not care one iota about his doggy siblings. What's with his lack of regard for them? If the dog were a human, how would you feel about his attitude toward his siblings? Or is this a normal attitude for a young person or young pup?
