Thank you for your query,
As you have washed the area with running water and soap after bite, your dog has been vaccinated, and your dog is still alive even after 28 days after the bite, nothing to worry.
There are no chances of getting Rabies
in this situation.
But consult your Physician once as he will advise you and reassure you in a proper way.
Take your pet dog to her regular Veternary doctor for the evaluation of decreased appetite.
Hope i have answered your query.
