She does a big roundhouse kick and the dog follows her foot
If you remove it it just looks like she's doing a roundhouse kick, same with the uppercut swipe thing in her WA
Go look at her throw animation, the dog does literally nothing during the attack part and doesn't even touch the opponent, if you watch it extremely closely there's a tiny bit at the end where she lands on it before returning to neutral but it's barely noticeable, I've seen her throw dozens of times and never noticed that until right now when I went through it frame by frame. So I guess not literally "literally" nothing, it does actually touch one of the two characters on screen for a couple of frames, but basically nothing.
And this barely looks worse than her normal 2D's nonsensical dust hitbox, if that's the most significant impact the dog has on her entire moveset I think it's pretty inarguable that it does "basically" nothing. If you remove Goldlewis's coffin, all his Typhoons would look weird as shit, if you removed Ky's sword or Faust's scalpel none of the attacks that use those would make any sense at all. Removing Rei results in, at worst, a couple of slightly awkward animations liker her 2D. For such a large element of her design visually that's an absurd waste.
