Now listen people - Spotted Dick is NOT made from blood or sausages or noses or kneecaps or anything else. ND you are thinking of Black Pudding, which is a sausage of dried blood, usually served with a "fry up" (ie. a fried breakfast). These misconceptions are precisely the reason that some Americans visit Britain on holiday with 2 weeks food in their suitcase, because they think that all we eat are squirrels and goat testicles etc.
FYI, Spotted Dick picture and recipe

As an amusing aside, Spotted Dick was renamed a few years ago by the "Politically Correct" lobby to Spotted Richard (Dick being a standard shortening of the name Richard) as the word Dick is interchangeable with the word penis etc. and they thought people might find it offensive to have to ask for the original dish. Thankfully though, this nonsense has now been dropped!
However sausage rolls and pies may contain
offal, although this is much more carefully controlled after the BSE crisis.
