I have several apple trees in my back yard, and ever since we've lived here, Lightning has loved apples. He'll bring a fallen apple into the house, present it to me, we have a little give and take that involves me exclaiming what an exceptional apple he found, then he settles down to eat it. I don't know if he eats any apples outside, but he'll bring four or five into the house a night sometimes. Stomps never once ate an apple (he was more of a traditional dog than Lightning is). Last year we had an ice storm very late in the winter that must have affected the apple trees, because I had no apples. So I would buy them at the store and throw them in the yard for Lightning. He ate them, but even he could tell it wasn't the same.
