We have had Suzie for 18 months and she has settled in reasonably well. When she first arrived she wasn't interested in food and although she now eats regularly she really only likes human food - probably what she was able to get when a stray. We have tried all different types of dog food but she still prefers chicken or the like. Would it be ok to feed her this kind of diet all the time? She obviously enjoys it and eats quickly. She is five years old. Many thanks.
