The Brown Dog affair was a political controversy about vivisection that raged in Edwardian England from 1903 until 1910. It involved the infiltration of University of London medical lectures by Swedish women anti-vivisection activists, pitched battles between medical students and the police, police protection for the statue of a dog, a libel trial at the Royal Courts of Justice, and the establishment of a Royal Commission to investigate the use of animals in experiments. The affair became a cause célèbre that reportedly divided the country.
The controversy was triggered by allegations that, in February 1903, William Bayliss of the Department of Physiology at University College London had performed an illegal dissection before an audience of 60 medical students on a brown terrier dog – adequately anaesthetized, according to Bayliss and his team; conscious and struggling, according to the Swedish activists. The procedure was condemned as cruel and unlawful by the National Anti-Vivisection Society. Bayliss, whose research on dogs led to the discovery of hormones, was outraged by the assault on his reputation. He sued for libel and won.
Anti-vivisectionists commissioned a bronze statue of the dog as a memorial, unveiled in Battersea in 1906, but medical students were angered by its provocative plaque – "Men and women of England, how long shall these Things be?" – leading to frequent vandalism of the memorial and the need for a 24-hour police guard against the so-called "anti-doggers". One doctor complained that the medical students' failure to overcome the police was a sign of the "utter degeneration" of junior doctors and the Anglo-Saxon race. On 10 December 1907, 1,000 anti-doggers marched through central London waving effigies of the brown dog on sticks, clashing with suffragettes, trade unionists, and 400 police officers, one of a series of battles known as the Brown Dog riots.
In March 1910, tired of the constant controversy, Battersea Council sent four workers accompanied by 120 police officers to remove the statue under cover of darkness, after which it was reportedly melted down by the council's blacksmith, despite a 20,000-strong petition in its favour. A new statue of the brown dog was commissioned by anti-vivisection groups over 70 years later, and was erected in Battersea Park in 1985. Peter Mason writes that all that is left of the old statue is a hump in the pavement, the sign on a nearby fence reading, "No Dogs".
