Also take into account the possibility she gained some muscle mass on a higher protein food. My dogs are heavier than others of the same size or larger. My 22 lb pug looks like an 18 lb foster. My personal dogs gained weight on an increased protein diet. Another thing, the NB Ultra foods only have 350-400 calories per cup versus 478 per cup of Orijen so if you’re feeding the same amount of Orijen as you were with NB, then you’re feeding more calories. Look up “Body Condition Score” and see where she fits on the scale.
