Why do you keep saying about wolf tails "thrashing back and forth" when they are anxious or irritated? It's feline body language! An anxious canine would pace around the room, slouch, lower their ears and possibly wag the tip of their tail if asks for something.
The "people like you" part of your reply already says enough. As for your insightful revelation about the people of Adastra not being "1:1 animal-like" - them being not like the animals of Earth doesn't cancel their species heritage, and the body language of people whose ancestors were felines looks out of place on canines.
