SZAT PRO Striped Teacup Pet Dog T-Shirts, 100% Cotton Tank Vest for Small Dogs and Cats, Sleeveless Puppy Clothes for Chihuahua Yorkie Red, 2X-Small

We have two very small Pomeranian puppies and neither of them like putting any clothes or anything on. However, once this is on they seem to be ok with it and will wear it for a good while before we decide it's time to take it off. It seems very cute looking but most importantly warm for them.
