Nope, not because of realism.
I have this thing where true anthropomorphs that are on 2 legs can talk. If they are on all fours I don't like talkers.
Are there others that feel the same.
I might be for a Eragon like mind link.
That would make for some nice inside jokes where BC THINKS Stuff and He-man summarizes differently.
BUT IN THE END I prefer that all fours don't speak
