Hi Roseann, most members including me, switch our puppies to an adult dog food formula around 6 or 7 months old, and at the same time reduce the feedings from 3 times a day to 2 times a day. I feed my guys 1 cup of Fromm's Lamb and Lentil kibble twice a day, once in the morning, and once in the evening. At a year old, Henry should be eating a adult dog food formula. Puppy food has extra calories, vitamins and minerals that a rapidly growing puppy needs, but now that he is older, his growth will be slowing down. You mentioned that he looks like he's getting chubby around his ribs, which is an indication you can probably reduce his food intake to 2 cups a day. He rule of thumb is when you look at him from above, you should be able to see a well defined waist, and when you feel his ribs area, you should be able to feel his ribs, but not see them. His pictures look great, he doesn't look like he's over weight, what does his vet say? My guys are 2 and 1/2 years old, and they weigh 45 lbs each, they don't look over weight to me, but my vet says she would like them to be more around 40 lbs. they tend to gain 2 to 3 lbs in the winter months, when they aren't as active or outside as much, but then in the Spring and Summer, they are running around more, and they go on lots of walks, so they lose it again. My vet says its it's better for them to be the lower weight, because it's better for their joints and hips as they get older.
