A couple years ago, in Yosemite, I met the woman who invented bear repellent. (I forget her name; sorry.) She was working on an experimental program of using "Karelian bear dogs" in the national parks to deter "habituated" bears from scavenging in campgrounds. She was currently working on this project at the Tuolumne Meadows campground. I got to see her use these dogs to tree a bear. It sounds absurd, because these bears are probably five to ten times larger than the dogs, but the bear did seem to be afraid of a couple dogs. The dogs were about 30-40 pounds each.
She said that the progam seemed to be working well. She also noted that she was only doing this experiment with black bears.
