My Standard is about 7 months old and weighs 43 lbs. We had her coat taken down pretty close the other day and she looks like she is starving to death. I feed her California natural twice a day 1 cup each time. The bags recommends 1 3/4 - 2 1/4 cups per day. My family thinks she looks toooooo skinny but I try to tell them that she is a puppy and I am feeding her what is recommended. She is very intergetic and doesn't seem to be deprived in any other way. Are Standards suppose to be a lightweight dog?
