Do you think it is the right thing to change the name of the dog in the remake of Dam Busters?

This has me very torn indeed. Here is the article about the new Dam Busters movies.

The dog is being renamed Digger because the name of the real dog that this is based on is now (quite rightly) an offensive term (replace the D with an N).

I am not questioning whether the N-word is offensive but seeing as this is based on truth and the dog (who’s grave you can apparently visit) was called Nigger because, apparently it means black in Latin (didn’t know that!) and the dog was a black Labrador.

Now, if this was a completely made up story then, of course, I wouldn’t agree with a character being called something so offensive but the fact that this is a part of history makes me wonder if it is right/necessary to change the name. I’m sure it won’t make any difference to the film, especially for the people that weren’t already aware of the story behind it and Hollywood changes historical fact all the time but I would like to know what others thoughts are.
