Do you want to feed kibble, canned or raw? Many of us would immediately suggest you feed raw, but you didn't pose this question in the raw forum, so I'm guessing you aren't thinking in that realm?
If canned, then I would suggest going with any grain free canned food. I wouldn't suggest feeding kibble, although many, many people do feed it, mainly because it's easy. (I, myself, fed it for too many years than I can count)
I see you are in Great Britain, so I cannot really offer brand names, because I don't know what is available over there, but hopefully some members from that side of the world will respond to you soon.
