At what age do you typically start paying attention to a pups body composition? My pup is almost 8 months and he doesn't over eat at all and doesn't get any "extras", but he's still a little soft and at 72lbs. He's not what I'd call overweight, the vet says he's perfect and he will fill out with muscle as he matures. But comparing him side by side with some of the other younger dogs at training days and what not, he definitely has a little more jiggle than a lot of them.
Currently he's getting 3 cups of TOTW per day (1.5 cups in the am, 1.5 cups in the pm), which is the minimum suggested daily amount on the back of the bag. He gets tons of exercise and has no shortage of energy or endurance. But if at all possible I'd like to stay on top of his weight rather than have to slim him down later, but not at the risk of possibly impacting his nutritional needs at this point in his growth.
So I'm not sure if it's anything I should even be concerned with at this point, should cut his food down, exercise him more, or something else?
