As Kay said above.
I've never few raw solely before, but did with my now 8 month old pup and he's flying.
He gets lamb breast, lamb or beef mice, chicken wings and carcasses, beef or whatever is reduced in Tescos.
The best bit is the nice hard little turds he does, dead easy to pick up, none of that stinking sloppy mess you get from dry food.
I thought it was going to be a load of hassle, but it isn't, dead easy once you get the routine.
