That's a lot of my problem. She's built kind of like a little sight hound only a bit less extreme. Her back is sloped some (incorrect for the breed but oh well), she's very narrow, deep chest but a big tuck up. Everything long enough is way too big around, even the adjustables. I need like half the width. She's 12 inches long, and 15 inches around her widest part. Here's a good shot to show how she's built: And here's the only sweater that I can find that fits her. I swear, she lives in it these days. She actually begs for it to be put on, lol. It's not even that cold yet!
