feeding mini pins

Question
i have this 3 month old mini pinscher and its my 1st time to hande a small breed of dog so im not quite sure on the amount of food i should feed him. could you give me an exact measuring guide i could use? (ex. 1 cup per meal,  etc.)

Answer
Anywere between half a cup,and a cup and a half per meal would be enough,sometimes you have to fool around with it for a bit before you get it it right,too much may make the dog vomit and or gain weight,too little and he will be hungrey all the time and lose weight

I would sart off with a cup per meal
