Just curious, one of my dogs is a mix from a shelter, so we have no idea what he is except a little bit border collie. I don't think I would ever do it but I was wondering if anyone else has, it seems interesting to me that you could find out that kind of thing.
I posted pics, I wasn't going to but why not I guess.

And I did check around, it's like 0 and I don't care so like I said I wouldn't do it. Just wondering if anyone else has, geeeeez.
