Gracie is a big girl to start off. Her Dad was a large English so she's always been a bit bigger but within the last year she went from 73 to 80 lbs. Same amount of exercise and food intake (Natural Balance Reduced Formula). The vet checked her thyroid -NORMAL!!! I am bummed she only gets 2 cups a day already and she got big. The vet suggested 1 cup in the morning and 3/4 at night and supplement with green beans. I give her beans once in a while anyway but I don't know how to get her with a healthy range. Help!
