Keep the dog active, a 1 hour or at least a 20 minute brisk walk every day will do wonders to keep a dog fit.
Choose a quality kibble, check the calories, Orijen is a good food but is higher in calories, so you would feed less and maybe add a topper (a spoonful of cooked ground turkey or something lean).
Nutrisca is a decent food and is a little lower in calories. Feed measured amounts twice a day and add a splash of water….especially if the dog is not a water drinker.
Do not free feed.
