232 dogs died in 1902 as a result of medical experiments.
Wikipedia gives: "In 1875 there were around 300 experiments on animals in the UK, a figure that had risen to 19,084 in 1903 when the brown dog was vivisected, and 4.11 million in 2012, 4,643 of them on dogs." The ethics of using animals for medical research are still being debated. One would like to think that the proper use of anaesthetics now ensures that animals do not suffer, though the continued existence of the National Anti-Vivisection Society suggests not.
