Hi, our guys are 21 months old, they both weigh 45 lbs. My vet says she would like to see them more around 40 lbs, I don't think they look overweight, but she says it's better for their joints to be on the lighter side. We feed them the same as you, 1 cup of kibble in the morning, and 1 cup of kibble in the evening. They get 1 Tbsp. of plain unsweetened yogurt on their morning kibble, and we give them cooked vegetables, on their evening meal. We give them whatever we are eating for dinner, such as cooked broccoli, cauliflower, carrots, or green beans. We feed them Fromm's Beef Frittata. Our vet suggested we feed 1 cup in the morning, and reduce the amount to 3/4 of a cup in the evening. How much does weigh? Ozzy looks good to me.
Heres some pictures of my two guys.
