7. Pomeranian
Pomeranians view themselves as royalty and react with swift, vocal indignation if you fail to treat them accordingly. Descended from large sled dogs, they retain a massive ego and a startlingly loud bark packed into a fluffy, diminutive frame. They demand constant mental engagement and spin frantically in circles to manifest their impatience. If you dare to stop scratching them prematurely, a Pomeranian will escalate from a soft grumble to a demanding yap until you correct your unacceptable behavior.
