What to do if there’s a bear living behind my house?

I’m not 100% sure but I’m pretty sure there’s a bear living in the woods behind my fence. I hear it back there at night when I let my dogs out. They lose their shit jumping at the fence- a 6ft privacy fence - and ive heard something behind there big af walking around and grunting. I know they can climb so I’m genuinely afraid for my dogs and myself. I let them out at night for their last pee and I hear it back there every night now. I just heard what sounded like it trying to climb my neighbour’s metal fence.

However I don’t know for sure if it’s a bear. I live in North Georgia in a big neighborhood but it’s pretty much built on a small montano so a bear wouldn’t be a ridiculous guess.

What can I do about this? Do I just have to live in fear? Or can I even call animal control if I don’t know for sure?

I’ve seen deer but whatever this is sounds big and makes grunting noises.
