Starving a dog in order to make it hungry enough to eat bear meat doesn't really fall in line with good animal care IMO.
Sometimes it's edible, sometimes it's not. I would no more expect that a grizzly be eaten - though it can be possible- than I'd expect fox or wolverine carcasses be salvaged for edible meat. It makes a lot more sense to require the salvage of prairie dogs and ground squirrels for human consumption than any of the above anyway.
