My darling Puss lived to be 19 on tinned/dried food - the only problem I had with her was her teeth. I choose to feed my dogs raw as I think its natural for them and its not necessarily about longevity of life but more health. I dont think there'll be concrete proof anywhere that one is better than the other - as always its personal choice and I feel my dogs are better on raw diet - the improvement in Bensons coat condition alone would swing it for me
