A beautifully done, honest animation.
It wasn't chronological, and it didn't make sense all the time, but the honesty that radiated from this animation could never be denied, and that's what makes it truly beautiful. Simply being able to experience life is a wonder and you portray that perfectly. You've created something that truly shows that Newgrounds can be a vehicle for more than just comedy, but for also the truer things in life.
As for the whole "puppy controversy," don't get too worked up about what other people have to say about you or your grandfather. Western society has a strange effect that spoils the majority of people and prevents them from seeing things in a different perspective. These people are ignorant and certainly not worth your time.
