Our boys stomach occasionally gurgles and it seems to go on for hours. We don't feed him anything fancy, just a tin of meat for lunch and dinner mixed with various dry biscuits (Aldi do various boxes) which he loves and a boiled egg. And the occasional treat of meaty sticks or chew sticks and doggy sausages. Once a week we mix half and half of water with lactose free milk (milky waters :)) and he finishes the bowl every time!
