Does Your Dog Like Apples?

We used to give our dogs chestnuts, apples and grapes during Christmas season (that's the only time we have those treats). But when I learned that grapes is not good for dogs, we stopped giving them fruits just to be safe. With roasted chestnuts, our dogs like it but with apples, I remember that only 1 of our dogs sampled it. Now it's only chestnut that we give our dogs. I didn't know that apple has healthy properties for dogs.
