Should survivors be able to pry off the dog?

Caiman

It's already difficult to land the grab, the grabbed survivor can already use a pallet to free themselves, the dog lets go if they fall off a ledge, and the dog lets go after roughly 10 or so seconds anyway. Is survivors pulling the dog off teammates really a necessary restriction on top of everything else? It looks ridiculous when they do it, the dog can't injure except outside of certain and narrow circumstances, and it will be rare for the Houndmaster to sic her dog on a survivor and not immediately follow up with an attack. I just don't see a reason this needs to be a part of the kit.
