We had 3 "escape artist" Newfies, so instead of having to respond to various calls that the dogs had gotten out again, I decided to install an electric fence around their dog run. They all watched with great interest as I installed insulators on the fence posts and strung the wires--very curious dogs.
Then here was the proof that in spite of their sort of dopey expressions, they are very, very smart. After I put power to the fence, the "leader" pup, the one who always led the escapes, started at one end, and tested each segment with his nose. He would let out a little yelp, then go on to the next segment, wash, rinse, repeat. At first I thought, "You dummy!" But then I realized that he was just making sure that all segments were hot, because if one was cold, that was the escape route. Of course, he didn't understand that the whole thing was either hot or cold. After his testing, he went over to where the other two dogs (his Momma and his brother) and somehow "told" them. We had no more escapes.
At first, when the battery ran down, I replaced it. But the next time it ran down, I just left it. I took the chance that they'd been convinced, and I was right. As I said, no more escapes.
How all that translates to keeping out bears, I haven't any idea.

Grizzly bears aren't quite that smart, but polar bears will go along the fence, testing it with a paw, looking for a weak spot.
