Riley is on eden holistic dog food, it has no cereal, fillers , beet pulp etc.
At first his poo went soft but when he adapted to it, he is fine.
We usually have 2 per day , not messy either , lol
He was on JWB as a pup but didnt do as well on the adult one so I searched for a new food and found eden, which is very similar to the likes of orijen etc,
Its really economical too as you dont need to feed large amounts , there is no waste, its 80% meat fish, and 20% fruit , veg and herbs etc.
Hope you finds something that suits.
