Okay. My 25 pound fairly active female sheltie gets 3/4 cup per day, no wet. My 26 pound very very active male sheltie gets 1 cup per day.

I would cut her food back to 1 cup per day and see if that helps. If she is not losing weight after about a month then cut it back to 3/4. If she is still acting hungry you can mix in some green beans or canned pumpkin to act as a filler.

Good luck with getting the weight off her
