It's the morning after, and naturally she wants to freshen up before we both head out for the day. Since I have quite a bit of extra toiletries, like the disposable ones from traveling, I tell her to help herself to whatever she needs while I get ready.

All's well and I hear the sink running, so I assume she's found what she need. Until a few minutes later when I hear

"This is such a cool brush. I never seen anything like this before"

And in her mouth, scrubbing away was my dog's brush. Now there isn't any markings or anything that would indicate that the brush was for a dog; just a metal shaft with the brush head. However the brush head looks nothing like a normal brush, it's two pronged with the bristles facing inward. 

At this moment I'm not really sure how to bring it up. I don't want to embarrass her. She keeps gushing on about it, looking so proud with herself. And the deed's already done. So I don't. Just nudged her back to the bathroom and tell her to wash up because breakfast is ready.

Should I have said something?
