Lola is 2 1/2 years. And she is small - 10.5 lbs. She is very active on her daily walk in the afternoon. I had never heard of stomach flip! Yuck. I think I would feed her at night, at least a half hour after her walk. Then she can lie around all evening digesting and sleeping, and poop it all out in the morning! At least that is my thinking.
Size has nothing to do with it - just age and maturity/development level.
Morridon, here's the answer to your question, and Redorr, to your question as well...
If you feed at night, I would say 1/2 hour after her walk is a great time. However, you are going to run into the issue of needing to go out in the middle of the night. Yes, that is why you're being woken at 3:00 or 4:00 in the morning.
I don't know what your schedule is, but if at all possible, I would feed by about 7:00 or 7:30, and make sure there is plenty of opportunity to potty before bed!
My dogs have a doggie door, so they can set their own schedule. Not because it's better for them....because I'm lazy that way and it's more convenient for me! haha
Having the stomach flip is much more common in large dogs, but it can happen in smaller dogs. The stomach literally moves around inside of them (flips) and causes a kink in the digestive tract. I know that's gross, but it's true.
