That's a long time between dinner and breakfast the next morning...currently the pup is going 16 hours without food.
It's not a huge deal, but sometimes when a dogs stomach is empty for a long time, they can spit up some pale, clear, foamy bile. It's just nature's way of saying "feed me!" So if you notice that, there you go.
My dogs also eat an early dinner because that works best for my schedule--so I compensate by giving a bedtime snack.
Just reserve a mouthful of his dinner and feed it as a bedtime snack. Or provide something else then. My dogs get a bedtime snack of a few spoonsful of yogurt. Just a little something so they don't go all night on an empty stomach.
At some point in the future (maybe at age 5 months or so) you can reduce the feedings to twice a day and space them out at 12 hours apart, or as close as you can manage.
I agree with Tracy. That is a long time that the pup is going without food-16 hours. I know it all does depend on the pup. Are you giving him anything in between the meals? I think a bed time snack would do him good, it doesn't have to be alot, just enough to get some food in his stomach.
