My gf knits them for her. Small dogs can benefit from the additional warmth clothes can provide during colder months.
A 2 pound puppy doesn't retain a lot of body heat on it's own.

My gf treats her like she's a little doll. She spoils it rotten and this sweet little puppy is still surprisingly well behaved. Quite a different animal from my 70 lbs Border Collie mix that passed 18 months ago.
