Rose slugs?

Thank you Lisa and Patty. Is it too late for me to do anything so that we can get the healthy leaves back?

Nope, those leaves's holes can't be fixed. But it's not a big deal. :) Every time I go outside, I look for holes such as that, turn the leaves over and squish any slugs by folding the leaf back over it until the larva is squished. If you check every day, then they'll only get one or two leaves, before you've dispatched them. If you keep the slugs at bay by doing this, then the plant will grow new unblemished leaves.

Usually after a couple weeks, the good predator bugs come along and gobble up the slugs and you won't see any more until next year around this time. The next set of leaves that emerge will be whole and healthy, but if the current leaves are too bad looking, just pluck off the worst ones so that the bush will look better until the new leaves emerge. (But don't pluck off all or most of the leaves, or your poor rose will have trouble manufacturing energy for growing and blooming.)
