when to feed?

I feed about 20 mins after a workout. Nothing extreme as far as workouts cause he's just a house dog... Workout about 15 mins, walk about 15 mins, come home, make a meal (a smaller portion than I usually feed of kibble and mix with a meat like chicken, fish or beef) wait about 20 mins and feed. I also feed him again later that evening. I like feeding him smaller meals about 3 times a day. Depends on the day though, if no workouts at all than its a morning and evening meal of dry kibble. I could definitely be wrong but that's what I've been trying =)
