Eye Help

These two sweeties need some help with buttons or some other idea for eyes.  The two pugs together have very small eyes and the one pug that will be sitting on a blanket has one eye that is almost covered.  I thought of adding some beads, but I worry that they will get chewed up and swallowed.  I had also thought that a hand embroidery stitch might work.  I don't do handwork, but if you know of a stitch that would work, let me know.

Thanks!
