Feeding from your hand isn't bad. I know many many people, and I would do the same if I fed kibble, that make the dogs work for every piece of their kibble. Throughout the day, using their kibble as treats in small training sessions. Or feeding half the allotted amount and using the other half for training sessions.

Don't worry, there are lots of ways to deal with things and someone will always find something wrong. But then that means someone will always find what you're doing right. :-D Lol
