This isn't to anyone, just a statement. I know what to do about black bears and taking my dog into those areas doesn't concern me. So far she has responded well to any exposure to black bears and listens to my commands. But I am certainly not using her as a defence against them. However, grizzly and wolf territory she is not familiar with and I am not willing to put her at risk of getting killed. Having her there could also exacerbate the situation when what we need is to be cool.
Besides that, there was one night where a bear ran by our camp and she was so tired she just slept through it all. For that matter, the wife and kids slept through it all as well.
