I am not sure giving her different foods - if different from what she has been eating - at this point is a good idea. Is the Primal venison the same as the Primal freeze dried food (sorry, not sure)? If not, it sounds like she was doing OK with the Primal venison. Whatever it is, I agree - don't think it is related to a tooth issue.Actually gave her different foods, most of which she ate with no problem.
