I think a lot depends on the dog. Mine gets cold pretty easy like in the summer unless she is outside she has to have a shirt on or the ac is to cold for her and in the winter its sweaters whether she is outside or inside. Fall is kinda tricky it goes from cold in the morning to kinda nice back to cold at night so sometimes I leave her fleece night gown on until it starts warming up put a kinda heavy shirt or light sweater on during the day and have to put something a little thicker on in the evening with the temps start dropping and she sleeps in her fleece nightie at night. Callie is 16 pounds so I'm not sure it necessarily has to do with weight. My moms yorkie Sammy doesn't get very cold and when Callie has to have a sweater on he normally does great in just tshirt and he too is about 16 pounds.
