I've only seen bears on TV, they look like fat dogs.
But I have no natural fear of them as we don't have any here.
Guess the lions ate them.
You are right, in the fall they do look fat (because they are) but that's what they gotta do to make it through winter ~ But ~ an adult Brown Bear can outrun a quarter horse in a sprint & believe it or not they seem even faster going up super steep hills.
