She sure as heck didn't take it off exercising.. LOL She gained 2.5# and her vet suggested that we take it off. We cut her back to 3/4 cup, twice a day from 1 cup each time. BUT, we think the big improvement came from switching from a junk treat to Blue Buffalo fish and sweet potato health bars broken into quarters. She could still 'count' her treats but was getting hardly anything in comparison.
