I worry about this too but Ollie does not always ask for food so I can't be giving too little... maybe I'm giving too much! LOL
I give him a little bit of puppy porridge in the morning (can't tell you the measurement I just fill up the bowl to about 1/4 of the way)
1/2 a cup of kibble for lunch usually mixed with yogurt or egg or fruit or vegetables.
Every other day I give him a chicken neck for lunch, is this too much for one whole meal?
And at dinner he gets another 1/2 cup of kibble mixed with yogurt and vegetables.
Through the day he gets dried liver for doing tricks and pieces of fruit as snacks
