chocolate, grapes- That is the first answer someone gave. I don't think those are actually undigestible, but they are poisonous to dogs. Among other POISONS are garlic and xylitol. As for undigestible, dogs cannot digest rawhide, and I'm 99% sure they can't digest bones.

Spicy foods and grains are difficult to digest.
