Hi, it’s cause the Kcals per cup are lower so you need to feed more, Kcalls per cup in TOTW Pine Forest is 337Kcals per cup & I feed TOTW Sierra Mountain, Roasted Lamb-338 Kcals Per Cup, I need to feed around 2 heaped cups of the TOTW kibble so the weight doesn’t fall off Patch, then I rotate & feed Canidae Pure Wild Boar 454Kcals per cup I feed 1 & 1/2 cup a day…..
Here’s a calculator & will give you an idea how many calories a day your dog needs but I also feed less so Patch is lean & all muscle, lean dogs live longer then fat dogs.
