I bought Paisley a Lupine collar for her birthday back in December and put it on her only once.. and that was the night I gave it to her. So I put it to use finally when I got Matlock on Jan.16th. It's purple, green, w/ some black outlining.. it looked girly on Paisley and now looks boy-ish on Matlock. So the pattern I chose was fine for both females and males. The pattern is called Splash. I bought the collar at a local pet store, it was about $12, and like someone previously mentioned, they're guarenteed, even if chewed! I'm pleased with it.
