A number said the system needs to change, while others said the food is so bad it's not suitable for dogs.
"That's an omelette? It looks horrific. And where are the vegetables? One can only recover properly on a balanced healthy diet," one wrote.

Another added: "Omg you wouldn't feed that to the dogs. My brother's in hospital at the moment and he was given a burnt shell pie and equally burnt beans the other day. Equally unsuitable for the dogs."
"That's not an omelette. That looks like a burnt Yorkshire pudding sandwich with an even more badly burnt salamander as filling."
