I mean, it’s Colorado, we are spoiled for choice (sigh). There was a reported mountain lion attack near Canon City last month, and a lethal bear attack this month in Lake City. I’ll add my +1 to trusting the dogs, and keeping a close eye on them and your surroundings. Maybe Parks and Wildlife has an update for your area?
Otherwise, yeah, bear spray as we both talked about in the recent thread:
And any other precautions you can reasonable take, which, well, you in the high country are probably more familiar with than I!
