Dwarves aren't cool anymore

But your premise was



And I know Redwall at least also doesn't have any elves or dwarves.

The more accurate summary of my premise is that fantasy races tend to be based on tropes that are more easily recognizable at a glance, while sci-fi races tend to be more alien (literally.)

So yes, while I only spelled out elves and dwarves, the same line of reasoning applies to anthropomorphic rabbits and wolves - we've had stories featuring all four for far, far longer than stories about Krogans and Twi'leks.
