Ben tries to always grab a toy and take it outside with him. He sneaks so many out, I have to pick up toys before I can ever mow. I think he has this last desparate thought that he does not want to get parted from his toys. My sister has one of his progeny and she takes a toy with her when they take walks! She said it is a funny site, but her little one is not happy unless she has a little toy with her. Maybe the kibble is sort of the same for your pup. Just doesn't want to get caught with an empty stomach.
