What would be Tetley's cup of tea?

Tetley, our beloved six-year-old German Shepherd cross is soon to arrive from the USA. There was lots of bureaucracy so I have got here before him! So, despite having records since birth and regular everything, we still had to act like she had never had a single shot in her life and she actually had to have two rabies shots within a month of each other as things must be done in a certain order or it's no dice.
In the States he was fed on Nutro after having some skin issues but you don't seem to have it here. What would be the nearest food to it?
She could do with losing a few pounds, but she should soon do that as there's some lovely walks around here.
