I don't know what Jazzie went thru before you got her, but I do know that Chloe does this and trust me, she has never been hungry a day in her life. She takes her food a kibble or two at a time and tries to bury it some place. While dusting the floor or running the sweeper, I am always finding pieces of kibble laying around. I had a dog some years back that did this and I free fed her! I believe some dogs have an instinct to bury food "for later" but really have no need to go back for it. If Willow discovers what Chloe is doing, she will follow Chloe and eat what Chloe leaves. They are funny to watch. They are both hard at their jobs. lol I can't free feed now because Willow is already over-weight and I know she would eat all the time if it were down.
Just another perspective.
