Japanese Spitz puppy - so cute you'd want to CRUSH IT!

I never knew Japanese spitz look THIS adorable as pups.

This is Cotton, a month old (I think) Japanese Spitz pup. It can't eat solid foods yet, it only drinks milk. Unfortunately, it's a curious little thing -- it went scavenging for food under the table and ended up swallowing a half eating shrimp. It choked on it. Its puke was, aside from the small bits of recognizable pink matter, white and not-so-yucky because of its milk diet.

I know it makes you "awwww" but it makes me go "AAAGGHH!!!"

As sweet as this guy (...gal? I'm not sure) they're said to grow into mean, jealous pets that would kill its competition (your cat, or your bird, or your other dog if it's small enough). Is that true?
