During the First World War the RSPCA provided support for the Army Veterinary Corps in treating animals such as donkeys, horses, dogs and birds that were co-opted into military service as beasts of burden, messengers and so forth.  The RSPCA's centenary in 1924 and its one hundred and fiftieth anniversary in 1974 were accompanied by books telling the society's story.  Since the end of the Second World War the development of intense agricultural farming practices has raised many questions for public debate concerning animal welfare legislation and the role of the RSPCA. This has included debates both inside the RSPCA (. the RSPCA Reform Group ) as well as among ethicists, social activists and supporters of claims for animal rights outside of it concerning the society's role in ethical and legal issues involving the use of animals.
