Have you seen the reports on Consumer Affairs about hundreds of sicknesses and some deaths in dogs who eat Nutro?

The itching could be caused by food, but there are so many possibilities.
The NB is a good one to try and you may hve to just wait it out.
That's not normally my favorite approach, but if she does this iwth most foods, you may have to. One downside to this method is sometimes when dogs don't eat, they throw up bile. Too much throwing up can be dangerous to a Yorkie and not eating can cause hypoglycemia, so I think I'd find a way to make her eat. You can mix something more appetizing in with the kibble, but they will start to expect it.
