When I was a child, we had a toy poodle who would ignore the apples that had fallen off the tree, instead he'd stand on his hind legs and walk under the tree, inspecting every hanging apple until he found one suitable. Then he'd pick it and eat it.
I would check with the vet about the fruit, just to be safe. I know dogs can't have grapes, and I'm wondering if grapes are related to prunes - they're both pitted fruit, sort of. Lol.
