I agree, somewhat, I give my dogs a bite of chicken (not a meal) when they come in from their bedtime bathroom break, it’s a reward, they expect it now.

I think the trick may be not to go more than 4 hours without having something in their tummy.

Also, if they are not water drinkers, add at least a splash or more to their 2 main meals per day.
I would not free feed, leave food out all day or use an automatic feeder. They will binge and get sick.
