I split Bob's recommended allowance into breakfast and evening meals. He doesn't always eat the breakfast one right away but most times it's all gone by the afternoon. Same with the evening one but his bowl is normally empty by somewhere around 8pm. He also gets a 'bedtime biscuit', heaven help me if I forget that!

p.s. he's always ready for people food and if leftovers are added to any meal it gets wolfed down right away!
