Well now Jasper will not wear clothes, he gets all spazzy and just stands still and will not move. Cookie is a tomboy and only wears them for pics and cold outside walks. Emma wears clothes all the time because she is under 2 pounds full grown and cannot maintain her body heat so she wears a sweater. I do change it to a tshirt when she it is warmer out. Clothes are terrible if you keep them in long coats though so my furkids keep puppy cuts so they can play dress up...
