There are patterns that you can either knit or crochet, that are good, but the tube sock would work fine, my youngest daughter always used socks as sweaters for her babies.
Now my older daughter was finally talked into taking chihuahua for a pet, now they have her spoiled rotten, they dress her up for Halloween (as a bat or an angel) and here is a picture she took of some kind of sweater she put on hers. Her chihuahua is a long haired chihuahua, she is very beautiful, of course her mother is my Buffy.
