Here is one of Bella's sock sweaters. It was a children's sock from Walmart originally. It's a silly pattern, but keeps her pretty toasty.
Bella is a little over two pounds, so the kids' size sock fits well. For bigger
Chis you can use a large adult sock, or even a man's sock. And if anyone
has medium sized dogs, for my 21 pound Basenji boys I used hockey socks.
Well the neck part does not fray because I did not have to cut it, I left it as is.
The leg holes and back part of the sweater do fray, so I either wash the sock in
the machine after I've cut it into a sweater, or I sew by hand the edges so they
don't fray, depends on the sock.
