If I knew there was a bear around, and I saw someone with a dog (leash or not) I'd let them know. I have in the past. They can do with that information whatever they wish.
As for what would I do if there was a hunter in the area, depends on where I saw the bear. Heading way off away from any trail? I'd probably tell them where I saw it. Heading toward a trailhead, then I'd just trade a few pleasantries.
