Emily gets 3/4 of a cup per day. 1/4 in the morning and 1/2 in the evening.

Clipse gets 1 cup per day. 1/2 in the morning and 1/2 in the evening.

one cup! Wow! Major gets 2 and a half! I guess the food isn't probably as good, meaning he needs more, but...wow!
You have to remember that Major is a growing pup and will be bigger than Ashley's shelties when he's done growing. So of course he will be eating more food than them.
