If he grows to be 10 lbs that is not your choice. But you should feed him 3 times a day, and I would say a 1/4 of a cup. But you can read the package, it should tell you how much for his weight and age. Also why are you feeding him nutical three times a day?? That has a lot of calories in it.. Is he sickly??
And by the way, I'm sorry but there is no such ting as a teacup.. My boy is only 2.5lbs and 6 months old and he isn't a teacup. He is a small yorkie that will not make standard.
