I'm glad the guy survived, crappy news about the dog though.
Out of all my years in the bush hunting and fishing etc, nothing ever scared me as much as getting rushed by an aggressive female bear. Seriously I don't think my heartrate returned to normal for at least 4 hours after the experience. That was just a few blocks from my house too, and I was with my kids. Thankfully it ended well and nobody was hurt/dead. Because I was unprepared for an incident, the only weapon I had was a lousy fillet knife, lol.
When a bear comes from 100 yards to 5 feet away in just a few seconds, it's quite the experience. Even with a gun, I'm not that confident I could shoot anything other then the head, anyhow.
Where I live in NW Ontario, the bears are becoming more aggressive and it just seems to come with the shift in nature. We now have an explosion of deer in the area, as well as rabbits. With them came cougars. My whole life I never saw a cougar in the wild, now in the last 7 years I've seen 3. The last one being two years ago, again, just by my house, actually almost the exact same spot the bear rushed me at, lol. Wolves as well, just seems like an explosion in the population lately, and all the animals mentioned are pushing more and more into populated areas.
