I knit it out of Cascade Fixation yarn, so it's cotton and stretchy. The best I could come up with. The design ties across her back, with one little support band across her chest. Best I could come up with. Hmmmm....I never thought to search in Ravelry. You never know....... there seems to be everything else in Ravelry.
Edited: I just checked Ravelry, and yes, there are doggie shrugs, plus leg warmers. The shrugs give too much coverage though, and the leg warmers - well there's nothing to keep them from being removed. Sooo..... I am happy with my design. It does the job, with minimal coverage, so she can stay cool. BUT - leave it to Ravelry! LOL
